MEID vs IMEI

Client

MEID vs IMEI compares 3GPP2 CDMA equipment identifiers with 3GPP cellular modem IDs. Multimode handsets often carry both. They use different lengths and Luhn radices—validate each with the matching tool.

Checksum comparison

MEID hex: 14 characters, Luhn mod-16. MEID decimal: 18 digits, Luhn mod-10. IMEI: 15 digits, Luhn mod-10, TAC prefix. Validate each with the matching Toolcore page.

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

  • Clarify identifier columns in MDM plus fleet CSV imports.
  • Train warehouse staff on two checksum families on one device label.

Common mistakes to avoid

  • Pasting IMEI into a MEID validation column

    IMEI is 15 decimal digits mod-10; MEID is 14–15 hex or 18–19 decimal.

FAQ

Is MEID the same as IMEI?

No—MEID identifies CDMA equipment per 3GPP2; IMEI identifies the cellular modem per 3GPP.
