MEID checksum checker

Client

CDMA and legacy dual-mode inventories often list MEIDs beside GSM IMEIs on the same asset row. This page accepts hexadecimal or decimal MEID forms, splits reporting body and serial fields, and recomputes the Luhn check digit—pair with IMEI checker when the label shows a 15-digit decimal identifier instead.

About MEID checker (CDMA)

14–15 hex or 18–19 decimal Mobile Equipment Identifier—Luhn mod‑10/16 check digit; RR/manufacturer/serial split—no TIA lookup; browser-only. The interactive transform on this page runs in your browser tab—Toolcore does not need your paste for the core operation described above.

How to use this page

Paste or type in the main workspace, run the primary action from the toolbar, then copy or download the result. Use Load example when the page offers it, or URL prefill (?q= / ?qb=) so agents and tickets open the same input.

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.

  • IMEI & IMEISV checker — 15-digit GSM IMEI: TAC/SNR split and Luhn verification; 14-digit check hint or 16-digit IMEISV segmentation—no carrier lookup; browser-only. when headers, identifiers, or reference tables need a sibling check.
  • ICCID checker (SIM) — 18–22 digit ICCID: telecom MII hint (89), E. when headers, identifiers, or reference tables need a sibling check.
  • Luhn checksum (mod 10) — Paste a digit string (spaces ignored)—pass or fail Luhn for PANs, IMEI-style IDs, and test vectors; browser-only. when headers, identifiers, or reference tables need a sibling check.
  • E.164 phone normalize — Strip formatting, normalize + / 00 / 011, validate ITU-style length; NANP +1 hint for 10-digit US/CA style—local only. when headers, identifiers, or reference tables need a sibling check.

Common use cases

  • Sanity-check a MEID copied from a handset sticker before loading it into a mobile device management CSV.
  • Explain why a hex MEID fails Luhn mod‑16 while a related IMEI on the same row still passes decimal Luhn.
  • Compute the trailing check digit when only a 14-digit hex body is available from a barcode scan.
  • Convert decimal MEID grouping to hex compact form for comparison against CDMA provisioning tools.

Common mistakes to avoid

  • Applying GSM IMEI rules to CDMA MEID hex values

    MEIDs with A–F use Luhn mod‑16 on the hex alphabet; all-decimal hex bodies use mod‑10—different from a 15-digit IMEI layout.

  • Expecting the check digit on the air interface

    The MEID check digit is for manual entry integrity—it is not transmitted over the radio link.

  • Treating a passing check as proof of carrier activation or blacklist status

    Checksum validation confirms format math only—not network registration, ESN/MEID allow lists, or stolen-device databases.

FAQ

Does Toolcore query TIA or carrier MEID databases?

No—the check digit and layout rules run entirely in your browser tab.

Hex or decimal—which should I paste?

Use whichever form appears on the label or export—this tool accepts 14–15 hex characters or 18–19 decimal digits after cleanup.

How does MEID relate to IMEI?

IMEI is the GSM/3GPP identifier (15 decimal digits with Luhn); MEID is the 3GPP2 CDMA identifier—multimode devices may expose both.
