IMEI check

Client

IMEI check is the head term for validating a handset modem identifier before paperwork, QA, or resale intake. Paste digits below for local Luhn, length guards, and TAC/serial readout—no live carrier or GSMA database query.

Typical IMEI check workflow

Copy IMEI from device settings or label → paste here → read Luhn and TAC → copy validated digits into your ticket or CSV. Pair with bulk IMEI check when reviewing manifests.

Why local checking matters

IMEIs can identify specific handsets in support logs. Browser-only validation keeps digits on the device instead of unknown cloud lookup services.

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

  • Confirm a pasted IMEI matches the About screen before opening a support ticket.
  • Batch-check IMEI columns in RMA or trade-in CSVs before ERP import.
  • Train counter staff to spot transposed digits on activation forms.

Common mistakes to avoid

  • Expecting IMEI check to prove carrier lock status

    Format validation only—lock and activation state require carrier tools.

  • Pasting MEID or serial where IMEI is required

    CDMA MEID and IMEI use different layouts—confirm the field label.

  • Treating Luhn pass as proof the device is not stolen

    No stolen-device registry lookup runs on this page.
