Bulk IMEI checker
Paste a list of IMEIs from a spreadsheet, invoice or stock sheet. We validate every number, flag typos and duplicates, identify each model and let you export a clean CSV.
How it works
- 01Paste up to 1,000 IMEIs, one per line or separated by commas.
- 02Click Validate all — each number is checked instantly in your browser.
- 03Filter to problems, then export the results as CSV.
Built for shops and resellers
Repair shops, refurbishers and wholesalers receive phones in batches. A single typo on an invoice can mean shipping the wrong device or failing a carrier check. Checking the whole batch at once catches those errors before they cost money.
What the bulk check covers
Every IMEI gets a length and Luhn check, duplicate detection and a model lookup from its TAC. It does not check blacklist status: for that, run a phone check on the devices you're unsure about.
Anatomy of an IMEI
Every IMEI has the same 15-digit structure. Each part tells you something different.
Type Allocation Code. Identifies the manufacturer and exact model. The first two digits are the reporting body.
Unique number the manufacturer assigns to this single device.
Calculated from the other 14 with the Luhn formula. Catches typos.
Frequently asked questions
How many IMEIs can I check at once?
Up to 1,000 per batch. Split larger lists into several batches.
Are my IMEIs uploaded?
Validation runs in your browser. Only the first 8 digits (TAC) are sent to look up the model.
Does it check if phones are blacklisted?
No, the bulk checker validates the numbers and identifies models. Blacklist status is a paid check per device.
