TAC - Identifies device model and manufacturer
SNR - Unique serial number
CD - Luhn algorithm check digit

Generate valid 15-digit IMEI numbers for device testing. Uses official Luhn algorithm verification. For development use only - illegal for real device tampering.

IMEI Generator: Valid Testing Numbers for Developers

What is this Tool?

The IMEI Generator creates valid 15-digit International Mobile Equipment Identity numbers using proper industry standards. These testing numbers follow the official Luhn algorithm verification and real-world IMEI structure. Perfect for app development, QA testing, and telecom system validation.

Key Formula: Luhn Algorithm

IMEIs use this verification system:

  1. Starting from right, double every 2nd digit
  2. If doubling results in >9, add digits together
  3. Sum all digits
  4. Valid if total modulo 10 equals 0

Example for 12345678901234?:

Original: 1 2 3 4 5 6 7 8 9 0 1 2 3 4
Doubled:  2 2 6 4 10 6 14 8 18 0 2 2 6 4
Sum: 2+2+6+4+(1+0)+6+(1+4)+8+(1+8)+0+2+2+6+4 = 59
Check digit = (10 - (59 % 10)) % 10 = 1
Final IMEI: 123456789012341 ✅

Formula Source

The Luhn algorithm (ISO/IEC 7812-1) was created by IBM scientist Hans Peter Luhn in 1954. This industry-standard formula is used globally for:

  • Credit card numbers (PAN)
  • National ID numbers
  • SIM card identifiers
  • IMEI validation systems

FAQs

Q: Can I use these for real devices?
A: No - generated numbers aren’t registered with GSMA. Real IMEIs require manufacturer certification.

Q: Why do some IMEIs fail validation?
A: Our tool ensures 100% valid numbers. If failure occurs, check for:

  • Extra spaces
  • Missing digits
  • Non-numeric characters

Q: Is this legal?
A: Yes for testing/development. Illegal if used for:

  • Device cloning
  • Fraudulent activation
  • Bypassing carrier blocks

Q: Why 15 digits?
A: Standard IMEIs contain:

  • 8-digit TAC
  • 6-digit SNR
  • 1-digit CD = 15 total digits

Critical Warnings

  1. Legal Compliance:

    • US federal law (18 U.S. Code § 1029) prohibits IMEI tampering
    • FCC regulations ban unauthorized device modifications
  2. Proper Usage:

    • Only for software testing
    • Never deploy to production devices
    • Avoid numbers from real phones
  3. Security:

    • Generated IMEIs may conflict with real devices
    • Cellular networks may flag test numbers
    • Use only in isolated test environments
  4. Ethical Guidelines:

    • Disclose test device status
    • Respect carrier policies
    • Delete after testing
