Competition Law and Verification Service Monopolies

Introduction

Verification services are services that establish, authenticate, certify, or validate the identity, credentials, status, quality, safety, compliance, or authenticity of a person, product, transaction, or business. Examples include:

• digital identity and KYC verification;
• credit and trust verification;
• professional-licence verification;
• product authenticity and certification;
• payment and transaction verification;
• age verification;
• cybersecurity and security certification;
• background checks;
• domain and certificate-authority services;
• platform “verified” badges and business verification.

A verification service monopoly arises where one undertaking, network, database, certification body, or platform becomes the only—or overwhelmingly dominant—source of verification that customers need in order to participate in another market.

Competition law does not prohibit monopoly itself. The central issue is whether the undertaking possesses substantial market power and uses that power to exclude competitors, exploit customers, restrict interoperability, discriminate between users, or extend its dominance into adjacent markets.

1. Meaning of Verification Service Monopoly

A verification provider can acquire market power because its verification is:

1. legally required;
2. required by a major platform or industry standard;
3. widely accepted by customers;
4. supported by an exclusive database;
5. difficult to replicate;
6. associated with strong network effects;
7. necessary for access to another market.

For example, suppose a dominant digital marketplace requires sellers to obtain verification exclusively from its own verification subsidiary. If competing verification companies could perform the same technical function but are denied access to the marketplace, the arrangement may raise competition concerns.

2. Relevant Market

The first competition-law question is defining the relevant market.

A. Product market

Possible markets include:

• identity-verification services;
• business-verification services;
• credit-information services;
• professional-certification services;
• cybersecurity certification;
• payment authentication;
• digital identity infrastructure;
• product-authentication services.

The market may be narrower where customers cannot realistically substitute one verification mechanism for another.

B. Geographic market

The geographic market can be:

• local;
• national;
• regional;
• global.

Regulation, recognition requirements, data-localisation rules, and licensing can make a verification market substantially national.

3. Why Verification Markets Can Become Concentrated

Verification services have several characteristics that can produce substantial market power.

3.1 Network effects

The value of a verification system increases when more:

• merchants;
• banks;
• platforms;
• employers;
• consumers;
• government agencies

accept its verification.

3.2 Data advantages

A verification provider may accumulate:

• identity records;
• transaction histories;
• fraud information;
• reputation scores;
• authentication histories;
• professional credentials.

Competitors may therefore face a data-access barrier.

3.3 Reputation effects

Customers may prefer the verification provider whose certificate is already recognized throughout the market.

3.4 Switching costs

Changing verification providers may require:

• re-verification;
• technical integration;
• regulatory approval;
• database migration;
• customer notification;
• contractual renegotiation.

3.5 Regulatory barriers

A certification or identity provider may need governmental authorization. Such requirements can legitimately protect consumers but can also make market entry difficult if unnecessarily restrictive.

4. Competition Concerns

A. Refusal to deal

A dominant verification provider may refuse access to its:

• verification database;
• authentication infrastructure;
• certification network;
• API;
• technical interface.

Where the facility is genuinely indispensable, refusal may raise concerns under the essential-facilities doctrine or comparable refusal-to-deal principles.

However, mere usefulness is generally insufficient. Competition authorities and courts normally examine whether the input is genuinely indispensable and whether refusal has exclusionary effects.

5. Discriminatory Access

A dominant provider may offer verification access to:

• itself on favourable terms;
• affiliated companies on favourable terms;
• established customers on favourable terms;

while charging competing verification providers substantially more or imposing discriminatory technical conditions.

This can create a vertical foreclosure problem.

For example:

Verification Provider A controls the industry-standard identity database. It provides its own downstream verification subsidiary instant access but delays or restricts access for competing verification firms.

The competitive concern is not simply unequal treatment. The relevant question is whether the discriminatory conduct disadvantages effective competitors and protects or extends market power.

6. Self-Preferencing

Self-preferencing can occur when a dominant verification platform gives its own downstream services preferential treatment.

Examples include:

• ranking its own verification service first;
• automatically selecting its own verification system;
• requiring customers to use its verification subsidiary;
• giving its own service superior API functionality;
• displaying its own verification badge more prominently.

This becomes particularly significant when the platform controls both the verification infrastructure and a downstream market.

7. Tying and Bundling

A verification monopoly may be leveraged into another market through tying.

Example

A dominant professional-verification provider tells customers:

“You may obtain access to our certification database only if you also purchase our background-check service.”

The competition questions include:

1. Is the verification database dominant?
2. Are the two services distinct products?
3. Is the verification service indispensable?
4. Does the undertaking impose coercive conditions?
5. Does the conduct foreclose competitors?
6. Is there an objective justification?

8. Excessive Pricing

A monopolistic verification provider may charge excessively high prices where:

• customers have no practical alternatives;
• entry barriers are substantial;
• the service is indispensable;
• prices are disconnected from economic value;
• customers cannot switch.

Excessive-pricing analysis is particularly relevant where the verification service is essential for access to regulated or network industries.

However, high prices alone do not automatically constitute an antitrust violation.

9. Margin Squeeze

A verification provider can also create a margin squeeze where it:

• supplies verification infrastructure to competitors at a high wholesale price; while
• offering its own downstream verification service at a price that competitors cannot profitably match.

The classic structure is:

upstream verification monopoly → downstream verification competition → discriminatory wholesale conditions.

10. Interoperability and API Access

Modern verification markets increasingly depend on APIs.

A dominant provider may restrict:

• API access;
• authentication protocols;
• data portability;
• interoperability;
• machine-readable certificates;
• verification tokens.

Competition concerns arise where technical restrictions are not objectively necessary but make it difficult for customers to use competing services.

Interoperability remedies can therefore become important.

11. Data Portability

Verification services often create proprietary data ecosystems.

A customer might accumulate:

• identity verification records;
• compliance histories;
• transaction verification data;
• trust scores.

If customers cannot transfer these records to another provider, switching costs increase.

Competition authorities may therefore examine whether the dominant provider:

• prevents portability;
• imposes unreasonable export fees;
• supplies incomplete data;
• uses incompatible formats;
• deletes verification histories when customers switch.

12. Exclusive Dealing

A verification monopoly can strengthen its position through exclusivity.

For example:

A dominant verification company requires banks, marketplaces, or employers to use its verification service exclusively.

Exclusive contracts can foreclose competing verification providers when they cover a substantial portion of demand and last for significant periods.

The analysis normally considers:

• duration;
• market coverage;
• entry barriers;
• availability of alternatives;
• foreclosure effects;
• legitimate business justification.

13. Predatory Pricing

A dominant verification company could temporarily charge below-cost prices to eliminate competing providers and subsequently raise prices.

For example:

1. entrant enters the market;
2. dominant firm substantially reduces verification fees;
3. entrant exits;
4. dominant firm raises prices.

Predatory-pricing analysis requires careful examination of pricing measures, costs, duration, recoupment where relevant, and exclusionary effects.

14. Verification as an Essential Facility

The essential-facility question is especially important.

A verification database or infrastructure is more likely to raise essential-facility concerns where:

1. access is indispensable;
2. duplication is technically or economically impracticable;
3. access is necessary for downstream competition;
4. refusal prevents effective competition;
5. access can technically be provided;
6. there is no adequate objective justification for refusal.

A competition authority should distinguish between a genuinely indispensable verification infrastructure and a merely convenient or commercially attractive service.

15. Major Case Laws

The following cases provide important principles applicable to verification-service monopolies, even where the underlying industry was not identity verification itself.

1. United States v. Terminal Railroad Association, 224 U.S. 383 (1912)

The Terminal Railroad Association controlled essential railroad-terminal facilities at St. Louis.

The Supreme Court found that control over an indispensable facility could create serious competition problems where competitors were effectively prevented from accessing it.

Principle

Where infrastructure is indispensable for competing in a downstream market, discriminatory or exclusionary access can attract antitrust scrutiny.

Application to verification

A dominant verification database that competitors genuinely cannot replicate could raise analogous concerns if access is denied selectively.

2. MCI Communications Corp. v. AT&T, 708 F.2d 1081 (7th Cir. 1983)

The case is a leading American authority concerning refusal to provide access to infrastructure.

The Seventh Circuit articulated criteria associated with essential-facility analysis, including practical impossibility of duplication and the absence of legitimate business justification.

Principle

A refusal to provide access becomes particularly significant when the facility is indispensable and competitors cannot realistically reproduce it.

Application

A unique national verification infrastructure could potentially be examined using similar reasoning.

3. Aspen Skiing Co. v. Aspen Highlands Skiing Corp., 472 U.S. 585 (1985)

A dominant ski operator discontinued cooperation with a competing operator despite previously engaging in a successful joint ticketing arrangement.

The Supreme Court treated the withdrawal of cooperation as potentially exclusionary because of the circumstances surrounding the refusal.

Principle

A dominant undertaking's termination of an established cooperative relationship may raise monopolization concerns where the conduct lacks a legitimate competitive explanation.

Verification application

If a dominant verification network historically interoperated with rival verification providers but abruptly terminates access specifically to exclude them, the factual circumstances could become important.

4. European Commission — Commercial Solvents v. Commission, Case 6/73 and 7/73 (1974)

Commercial Solvents involved a dominant supplier of an essential input that sought to restrict supplies to downstream competitors.

The European Court of Justice recognized that a dominant undertaking controlling an important upstream input can violate competition law by restricting supplies to downstream competitors.

Principle

Dominance at one level of a supply chain cannot legitimately be used simply to eliminate competition at another level.

Verification application

A dominant verification-data provider could face analogous concerns if it controls an indispensable upstream verification input and selectively restricts downstream rivals.

5. Bronner v. Mediaprint, Case C-7/97 (1998)

The European Court of Justice considered whether a dominant newspaper distributor was required to provide access to its distribution system.

The Court adopted a demanding standard for compulsory access.

Principle

A facility is not an essential facility merely because access would make competition easier. The input must generally be indispensable and lack a realistic substitute.

Verification application

This principle is particularly important for verification databases. A competitor should not automatically obtain access merely because the database would improve its commercial position.

6. IMS Health GmbH & Co. KG v. Commission, Case C-418/01 P (2004)

IMS Health concerned access to a commercially important database structure.

The European Court of Justice considered when refusal to license intellectual-property-protected infrastructure could constitute abuse.

Principle

Compulsory access to protected infrastructure requires exceptional circumstances, including indispensability and potential elimination of effective competition.

Verification application

A proprietary verification database should not automatically be opened to competitors. The analysis must establish the necessary exceptional circumstances.

7. Microsoft Corp. v. Commission, Case T-201/04 (2007)

Microsoft concerned interoperability information and Microsoft's control over important technological interfaces.

The European Union courts upheld competition-law concerns relating to Microsoft's refusal to provide interoperability information.

Principle

Control over interoperability information can become an important source of market power where competitors require it to compete effectively.

Verification application

A dominant verification platform that withholds technical interoperability information necessary for rival services may face comparable concerns.

8. Slovak Telekom a.s. v. Commission, Joined Cases C-165/19 P and C-165/19 P-related proceedings (2021)

The European Court of Justice considered exclusionary conduct involving access to telecommunications infrastructure.

The case is important to the modern treatment of infrastructure access and foreclosure.

Principle

A dominant vertically integrated undertaking controlling infrastructure can face Article 102 TFEU scrutiny when its conduct restricts downstream competition.

Verification application

The reasoning is relevant where a verification infrastructure provider competes downstream with firms that require access to the infrastructure.

16. Indian Competition-Law Perspective

Under the Competition Act, 2002, verification-service monopolies can potentially raise issues under:

• Section 4 — abuse of dominant position;
• Section 3 — anti-competitive agreements;
• Section 5 — combinations where verification infrastructure is involved in mergers;
• Section 19 — inquiry into combinations of conduct and dominance;
• Section 26 — investigation procedure;
• Section 27 — orders against abuse of dominant position.

Potential Section 4 theories include:

Section 4(2)(a)

Unfair or discriminatory:

• conditions; or
• prices.

Section 4(2)(b)

Limiting or restricting:

• production;
• technical or scientific development;
• access to markets.

Section 4(2)(c)

Denial of market access.

Section 4(2)(d)

Imposing supplementary obligations unrelated to the subject matter of the contract.

Section 4(2)(e)

Using dominance in one relevant market to enter into or protect another relevant market.

That last provision can be particularly important for verification-service monopolies.

17. Indian Case Law Relevant to Verification Monopolies

9. CCI v. Fast Way Transmission Pvt. Ltd. & Others

The Competition Commission of India examined allegations concerning market access and restrictive conduct involving cable television infrastructure.

Principle

Control over an important infrastructure layer can affect competition in downstream markets.

Verification application

Where a verification infrastructure provider controls access necessary for competing downstream services, market-access concerns may arise.

10. Shamsher Kataria v. Honda Siel Cars India Ltd. & Others

The CCI examined restrictions involving automobile spare parts and repair information.

Principle

Control over important technical information and after-sales infrastructure can affect independent competitors.

Verification application

A verification provider controlling essential technical information or certification data could similarly affect downstream competition.

18. Verification Monopolies and Digital Platforms

Digital platforms present particularly difficult cases because verification can be combined with:

• identity;
• reputation;
• payment;
• advertising;
• search ranking;
• recommendation systems;
• fraud detection.

A platform may therefore operate a chain such as:

Identity data → Verification → Trust score → Ranking → Transactions → Payments

If one undertaking controls multiple layers, competition authorities may examine whether dominance at one layer is being leveraged into adjacent markets.

19. Verification Badges and Platform Power

A platform's verification badge can become commercially important.

For example, if:

• verified sellers receive greater visibility;
• verification is available only through the platform;
• external verification is not recognized;
• verification affects search ranking;

the verification system can become an important competitive input.

The analysis should distinguish between legitimate fraud-prevention objectives and conduct that unnecessarily excludes competing verification providers.

20. Verification Standards and Interoperability

Industry standards can have both pro-competitive and anti-competitive effects.

Pro-competitive effects

Standards can:

• improve trust;
• reduce fraud;
• facilitate transactions;
• increase interoperability;
• reduce consumer search costs.

Competition risks

Standards may become problematic if dominant firms use them to:

• exclude competing technologies;
• prevent alternative certification;
• impose discriminatory technical requirements;
• control access to standards;
• manipulate standards-setting processes.

21. Legitimate Business Justifications

Verification providers can have legitimate reasons for restricting access.

These include:

• cybersecurity;
• fraud prevention;
• privacy;
• regulatory compliance;
• authentication integrity;
• protection against identity theft;
• data-security concerns;
• intellectual-property protection.

Competition law should therefore distinguish between:

genuine security restrictions

and

restrictions designed primarily to exclude competing providers.

The existence of security concerns does not automatically establish an antitrust violation, but neither does invoking security automatically justify exclusion.

22. Remedies

Where competition authorities establish unlawful exclusion, potential remedies can include:

Structural remedies

• divestiture;
• separation of infrastructure and downstream operations;
• limits on ownership concentration.

Behavioural remedies

• non-discriminatory access;
• reasonable access pricing;
• interoperability obligations;
• API access;
• data portability;
• prohibition of exclusive dealing;
• prohibition of discriminatory verification.

Technical remedies

• interoperable APIs;
• standardized verification formats;
• portability mechanisms;
• open authentication protocols.

23. Compliance Framework for Verification Providers

A dominant verification provider should establish:

1. objective access criteria;
2. transparent pricing;
3. non-discriminatory API policies;
4. documented security requirements;
5. independent review of refusals;
6. data-portability mechanisms;
7. clear interoperability standards;
8. separation of infrastructure and downstream commercial decisions;
9. competition-law review of exclusivity clauses;
10. monitoring of self-preferencing.

24. Analytical Framework

A competition authority can analyse a verification-service monopoly through the following sequence:

Step 1 — Identify the verification service

↓

Step 2 — Define the relevant product and geographic markets

↓

Step 3 — Assess dominance

Consider:

• market share;
• barriers to entry;
• network effects;
• data advantages;
• switching costs;
• regulatory requirements.

↓

Step 4 — Identify the conduct

• refusal to deal;
• discriminatory access;
• tying;
• bundling;
• exclusivity;
• excessive pricing;
• margin squeeze;
• self-preferencing;
• interoperability restrictions.

↓

Step 5 — Determine competitive effects

Examine:

• foreclosure;
• entry deterrence;
• reduced innovation;
• higher prices;
• reduced quality;
• reduced consumer choice.

↓

Step 6 — Examine objective justification

Consider:

• privacy;
• security;
• technical necessity;
• regulatory obligations;
• legitimate efficiency.

↓

Step 7 — Consider remedies

• access;
• interoperability;
• portability;
• non-discrimination;
• behavioural or structural remedies.

25. Key Legal Principles from the Cases

Conclusion

Verification-service monopolies occupy an important intersection between competition law, data governance, digital infrastructure, and regulation. The mere existence of a single verification provider is not necessarily unlawful. The critical question is whether the provider possesses dominance and uses control over verification infrastructure, data, certification, or interoperability to exclude competitors, deny market access, discriminate against rivals, or leverage dominance into adjacent markets.

The most important legal concepts are abuse of dominance, refusal to deal, essential facilities, discriminatory access, tying and bundling, exclusive dealing, margin squeeze, self-preferencing, interoperability, and data portability.

For modern digital markets, the central competition-law question can be expressed as:

When verification becomes an indispensable gateway to another market, control over the verification gateway can itself become a source of market power—and competition law may intervene where that power is used to foreclose effective competition.
