MEID decimal format

Client

MEID decimal format uses 18 digits: ten for manufacturer encoding and eight for serial, plus optional mod-10 check digit. Equivalent hex can be derived when values fit 32+24 bit limits.

Decimal to hex mapping

When within bit limits, decimal manufacturer and serial convert to eight and six hex characters respectively for field display alongside checksum validation.

Privacy: checksum math runs locally in your tab. Toolcore does not query carrier or TIA MEID databases—format and Luhn check only.
?

CDMA MEIDs appear as 14 hexadecimal digits plus an optional check digit (15 total), or as an 18-digit decimal form with its own check digit. Hex values containing A–F use Luhn mod‑16; all‑ decimal hex uses Luhn mod‑10—same family as IMEI on GSM handsets.

Result

GSM devices use IMEI instead—open IMEI checker when the label shows a 15-digit decimal identifier.

Common use cases

  • Explain decimal labels on legacy CDMA intake forms.
  • Cross-check decimal paste against hex sticker photos.

Common mistakes to avoid

  • Assuming any 18-digit string is a valid MEID

    Manufacturer and serial fields must fit MEID bit limits when converted to hex.
