Device Testing Tool

IMEI Generator

Generate Luhn-valid 15-digit test IMEI numbers for device forms, QA fixtures, mock inventories, and development. The output is synthetic and is not linked to real hardware.

IMEI Generator

Generate Luhn-valid 15-digit test IMEI numbers for device forms, QA fixtures, mock inventories, and development. The output is synthetic and is not linked to real hardware.

How to Generate a Test IMEI

  • Choose how many identifiers you need.
  • Select a labeled device profile, or provide an 8-digit TAC from your own test specification.
  • Generate the batch and copy individual values or export the full result.
  • Keep the seed when a bug report or automated fixture must reproduce the same identifiers.

What Makes an IMEI Valid in Format?

An IMEI contains 15 digits: an 8-digit Type Allocation Code, a 6-digit serial section, and a final Luhn check digit. This tool calculates that checksum correctly.

Passing a checksum only confirms the number's structure. It does not mean the identifier was assigned by the GSMA, belongs to a phone, or can be used on a mobile network.

Useful IMEI Testing Scenarios

  • Validate input length, numeric-only rules, and checksum handling.
  • Populate device-management screenshots and staging inventories without copying real identifiers.
  • Exercise CSV imports, API payloads, deduplication, and error states with repeatable batches.
  • Document device onboarding flows with clearly synthetic sample data.

Frequently Asked Questions

Are these real device IMEI numbers?
No. BestRandom creates synthetic test identifiers. A generated IMEI may pass the Luhn checksum, but it is not proof of a real device or network registration.
Do generated IMEIs pass the Luhn check?
Yes. Each result contains a 14-digit payload followed by a calculated Luhn check digit.
Can I use my own TAC prefix?
Yes. Enter an 8-digit TAC from your own test specification. BestRandom adds a random serial section and a valid check digit.
What are device profiles used for?
Profiles make test batches easier to label. Their included TAC values are synthetic placeholders and are not claimed as GSMA allocations.
Can I reproduce an IMEI batch?
Yes. Keep the same seed and options to generate the same deterministic test batch.
How do I get the best results from IMEI Generator?
Start with the default settings, then adjust Number of IMEIs, Device profile, Custom TAC (optional) based on your use case.
Can I reproduce the same IMEI Generator output later?
Yes. Keep the same seed and options, then run it again.
Is IMEI Generator suitable for team or classroom use?
Yes. Share the URL with seed and options so everyone sees the same setup.
How many times should I run IMEI Generator?
For quick tasks, one run is often enough. For exploration, compare multiple runs.
