Verify IMEI number

Client

Verify IMEI number searches usually mean checksum validation before retyping into portals—not live entitlement lookup. Paste below for Luhn, segment readout, and suggested check digit on failure.

What verification covers here

Verification means length guards, decimal cleanup, Luhn mod-10 on standard IMEI, and TAC/serial segment hints. It does not contact carriers, OEM warranty APIs, or lost/stolen lists.

Typical verify workflow

Copy IMEI from About screen or label → paste here → quarantine Luhn-fail rows → re-scan labels before carrier or resale steps.

Privacy: digits are parsed only in your browser—no carrier or GSMA lookup, no upload. Treat device identifiers like any sensitive paste on shared machines.

A 15-digit IMEI is commonly described as eight-digit TAC + six-digit serial + Luhn check digit; the trailing digit should satisfy ISO/IEC 7812 mod 10 on the full string—same arithmetic as debit/credit PAN checks. A 16-digit IMEISVappends two software version digits instead of exposing the standalone check position; carriers may still relate it to IMEI numbering but this page stops at segmentation and does not certify assignment.

Result

Passes Luhn mod 10 on the 15-digit string.

  • TAC (8): 35693803
  • Serial (6): 564380
  • Check (1): 9

Common use cases

  • Verify IMEI numbers in CSV columns before bulk ERP import.
  • Confirm OCR scans from device labels before opening support tickets.
  • Replace spreadsheet macros on laptops that block external add-ins.

Common mistakes to avoid

  • Treating verify as carrier activation proof

    Passing Luhn does not mean the line is active or unlocked.

  • Pasting MEID hex where decimal IMEI is required

    Confirm the form label—CDMA MEID uses a different layout.

  • Expecting verify to query a stolen-device registry

    No blacklist or GSMA database call runs on this page.
