IMEI batch CSV validator

Client

IMEI batch CSV validator is for spreadsheet and ERP exports pasted as plain text. Copy the IMEI column—one modem ID per line—and scan pass/fail before upload to activation or WMS systems.

Batch CSV workflow

Export IMEI column → paste one per line here → quarantine Luhn-fail rows → fix or re-scan labels → proceed to carrier or inventory systems.

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

  • IMEI batch CSV validator before overnight ERP import jobs.
  • Clean supplier manifest columns at receiving dock.
  • QA sample from marketplace bulk seller uploads.

Common mistakes to avoid

  • Pasting comma-separated rows as one line

    Use one IMEI per line for per-row results.

  • Uploading CSV to unknown cloud validators

    Paste locally—manifests may list customer assets.

  • Assuming batch pass means no duplicate IMEIs

    Luhn validates format—dedupe separately in your spreadsheet.

FAQ

How many IMEIs can I batch paste?

Practical limit is browser memory—paste reasonable column sizes; split very large files.

Does batch CSV validator upload files?

No—copy/paste text only; processing stays local.

Excel scientific notation in CSV?

Fix upstream or paste from source of truth—truncated digits fail Luhn.
