Software Usage Instructions

Set generation parameters: Enter the generation quantity in “Parameter Settings”; you can choose 1 to 10000 entries. If you need to specify a device type, enter an 8-digit TAC prefix.
Select device brands: Check the brand TAC ranges you want to use. Multiple brands are supported, including Apple, Samsung, Xiaomi, Huawei, OPPO, and Vivo, with quick buttons for select all, deselect all, invert selection, and common brands.
Configure advanced options:
- Generate only unique IMEIs: Automatically filters duplicate numbers.
- Use a valid Luhn check digit: Calculates the 15th check digit according to IMEI rules.
- Include brand when copying text: Adds the brand after each IMEI when copying or exporting to TXT.
- Display format: Supports plain digits, TAC/serial number/check digit, hyphen-separated segments, and space-separated segments.
- Download format: Supports three result file types: TXT, CSV, and JSON.
Start batch generation: Go to the “Generate & Export” page and click “Start Batch Generation”. The system will display the generated quantity, unique quantity, valid check quantity, brand count, and time taken.
View and export results: Search by IMEI or TAC, filter by brand, and copy all results, copy filtered results, or download the file.
Batch verify IMEIs: Paste IMEI text in “Batch Verification”, or select TXT, CSV, or JSON files for verification. After multi-file processing, the results will be packaged as a ZIP download.
Save settings and view history: Save the current parameters for reuse next time. Generation history records the quantity, time taken, brand, and sample IMEI.

FAQ

A: They are not recommended for use as real device identities. The tool generates simulated data for development testing, data population, format demonstrations, and system debugging. Do not use it to forge device identities or for any other prohibited purposes.

A: TAC is the first 8 digits of an IMEI and is used to identify device brand, model, and other type information. After you enter a custom TAC, the tool will prioritize using that prefix to generate IMEIs.

A: Luhn validation is used to calculate the 15th check digit of an IMEI and can help detect length errors, digit entry errors, or check digit mismatches.

A: After enabling “Generate only unique IMEIs,” the tool filters out duplicate results. If the brand range is small, the TAC is fixed, or the quantity is large, there may not be enough available combinations. You can increase the brand range or adjust the TAC settings.

A: TXT, CSV, and JSON are supported. TXT is suitable for quick copying and text processing, CSV is suitable for spreadsheet analysis, and JSON is suitable for programmatic reading and API testing.
