What is an IMEI?
The International Mobile Station Equipment Identity (IMEI) is a unique 15-digit serial number used to identify every mobile device on a cellular network. It acts as a digital fingerprint for your phone.
- Identifies valid devices to networks
- Helps blacklist stolen phones
- Required for unlocking network carriers
IMEI Structure Breakdown
A standard 15-digit IMEI number is composed of three distinct parts that provide information about the device's origin and model.
Format: TAC - SERIAL - CHECK
TAC (8 digits): Type Allocation Code (Brand/Model)
Serial (6 digits): Individual device number
Check (1 digit): Luhn checksum digit
How to find your IMEI?
Finding your device's unique identity is easy. Use the universal code on any phone or check your device settings.
Frequently Asked Questions
What does it mean if an IMEI is valid?
A "Valid" result means the number passes the Luhn algorithm test. It doesn't necessarily mean the device is not blacklisted; it only confirms the number is mathematically correct.
Can an IMEI be changed?
In most jurisdictions, changing or tampering with an IMEI number is illegal. It is hardcoded into the device's hardware to prevent theft and fraud.
What is the TAC code?
The first 8 digits (TAC) identify the device model and manufacturer. For example, specific TAC ranges are assigned to iPhones, Samsung Galaxy models, etc.
Are generated IMEIs real?
Our generator creates mathematically valid numbers based on real TAC prefixes. These are intended for software testing and development only.
