The IMEI Debate: Can Governments Protect the Market Without Creating New Cybersecurity Risks?

Every smartphone carries a unique digital fingerprint. That identifier can help block stolen devices, fight smuggling, and enforce customs rules. But when that identifier is connected to people, SIM cards, import records, travel information, and operator data, a market-control tool can become a cybersecurity target.

What Is an IMEI and Why Does It Matter?

An IMEI is the 15-digit number assigned to a mobile device. Operators use it to recognize equipment and block phones reported lost or stolen. The real debate is how widely those identifiers should be registered, linked, and used.

Many European operators rely on shared blocklists, including the GSMA Device Registry, to stop lost or stolen phones from reconnecting. This narrower approach does not generally require every lawful phone to be registered to a named user. It helps deter theft, but does little to address undeclared imports or tax evasion.

Broader systems in Turkey, Azerbaijan, Pakistan, Indonesia, and Nepal connect network access to import status, registration, customs compliance, and sometimes identity documents. They can combat smuggling, cloned IMEIs, and counterfeit devices, but they concentrate more information and control.

Armenia is now considering this broader model. On 25 June 2026, its Government approved draft amendments introducing mandatory IMEI registration. The stated goals include reducing undeclared imports, counterfeit devices, tax losses, and unfair competition. Phones that cannot be confirmed as legally imported or properly registered could be denied access to networks. The Cabinet-approved proposal must still complete the legislative process.

International experience shows both sides. Azerbaijan reported blocking more than 73,000 cloned IMEI codes in June 2026. Nepal offers a governance warning. In March 2025, two former telecom-regulator chiefs, a foreign national, and three companies were convicted over corruption in the procurement of its Mobile Device Management System. This was not a cyberattack, but it showed that weak oversight can undermine a system before technical security is tested.

What Data Protection Risks Do IMEI Registries Create?

The Armenian Government has said its system will retain only a device’s IMEI and will not collect personal data. The published draft, however, describes information relating to IMEIs, their users, active SIM or eSIM numbers, and the lawful circulation of phones. It also permits links with operator, customs, state, and border-management systems.

The draft does not confirm that names or passport copies will be stored centrally. Nor does it support the simpler claim that only IMEI numbers will be involved. Exact data fields, retention periods, access rights, and exchange procedures are left to later regulation.

Who Operates and Controls an IMEI Registry?

The state would formally manage the registry, while technical administration could be delegated to an organization created jointly by Armenia’s mobile operators. That non-governmental administrator could handle architecture, data processing, maintenance, security, and database connections. The draft also allows registry data to support additional digital services.

This does not prove misuse. It does increase the need for strict purpose limits, transparent contracts, independent audits, and clear accountability.

Cybersecurity Risks of a Centralized IMEI Registry

A single IMEI reveals little. Its value changes when linked to a user, SIM or eSIM, import records, border checks, and operator information.

The threat is not limited to an external hacker. It includes insiders with excessive privileges, contractors accessing unnecessary information, unauthorized searches, manipulated records, wrongful device blocking, secondary uses, and attacks that make the registry unavailable. Because network access may depend on the system, corrupted records could affect legitimate users too. For ordinary users, an incorrect, manipulated, or unavailable registry record could mean that a legally owned phone is suddenly unable to connect to the mobile network.Local cybersecurity and data-protection experts have also warned about unauthorized access, leaks, misuse, and increased traceability.

Questions that must be answered

What information will be stored? Who can access linked records? How long will it be retained? Will privileged actions be logged and reviewed? Who investigates insider misuse or a breach? What appeal process protects a lawful user whose phone is blocked?

The success of any national IMEI registry depends not only on its objectives but also on how it is designed, governed, secured, and independently audited.

This approach may help reduce illegal imports and protect legitimate businesses. The broader lesson applies far beyond one country: a system built to protect the market should not become a new source of risk for the people, data, and networks it is meant to serve.
