What Is an IMEI Number

Updated May 2026

An IMEI, or International Mobile Equipment Identity, is a 15-digit identifier used to distinguish a mobile device on supported networks and support systems.

In practical workflows, IMEI values appear in mobile support tools, setup screens, inventory systems, warranty checks, enterprise management systems, and QA environments.

What the IMEI identifies

The IMEI identifies the device hardware profile rather than a phone number or user account.

It is commonly used in support records, diagnostics, compliance workflows, and device registration systems.

Where people see IMEI numbers

Users usually see IMEI references in phone settings, device packaging, support portals, carrier tools, and onboarding forms.

Product teams also use sample IMEI values when building or testing interfaces that require a realistic device identifier field.

Why sample IMEIs are useful

Sample IMEIs help teams test forms, screenshots, admin dashboards, and QA scenarios without exposing real device identifiers.
