IMEI Generator for Testing and Development
Generate valid 15-digit International Mobile Equipment Identity numbers directly in your browser without any external dependencies. This workspace combines five essential utilities: a precision generator with manufacturer filtering, a batch-ready Luhn validator, a deep-dive TAC decoder, a bulk engine for large datasets, and an educational checksum calculator. By using authentic Type Allocation Code prefixes from brands like Apple and Samsung, your generated numbers maintain structural integrity for realistic testing. Since everything processes locally on your machine, your data stays private and secure.
IMEI Generator
Generates valid 15-digit IMEIs with real TAC prefixes and correct Luhn check digits. Supports manufacturer filtering.
IMEI Validator
Validates single or batch IMEI numbers using the Luhn algorithm. Supports file upload for bulk checking.
IMEI Info Decoder
Decodes IMEI structure showing TAC, serial number, reporting body, and manufacturer identification.
Bulk Generator
Creates up to 1,000 valid IMEIs in one batch with CSV export and optional manufacturer filtering.
Checksum Calculator
Computes Luhn check digits with a step-by-step breakdown of the algorithm for educational reference.
How the Online IMEI Generator Works
Think of an IMEI as a digital fingerprint for mobile devices. This 15-digit identifier is split into three main parts: the 8-digit Type Allocation Code (TAC) for manufacturer info, a 6-digit serial number, and a final Luhn check digit. The system pulls from public GSMA records to provide you with authentic TAC prefixes, ensuring the numbers you generate are perfect for database prototyping, QA cycles, or learning about mobile network protocols.
Real TAC Prefixes from Known Manufacturers
Start your generation with confidence by selecting specific manufacturer prefixes that match your test requirements. Whether you need identifiers for an iPhone, a Pixel, or a Galaxy device, you can filter by major brands or let the tool pick a random valid prefix for you. All manufacturer data is cross-referenced with GSMA allocations to keep your test data as accurate as possible.
Luhn Algorithm Verification Built In
Accuracy is baked into every number through the Luhn (mod 10) algorithm. The 15th digit is a calculated checksum that validates the preceding 14 digits by doubling even positions and summing the results. If you want to see exactly how this math works, the built-in checksum explorer provides a clear, step-by-step visualization of the entire calculation.
Validate, Decode, and Generate IMEI Numbers in Bulk
Manage all your mobile identifier tasks in one place. You can quickly verify any IMEI to ensure its checksum is correct or drop in a file for high-speed batch validation. When you need to know more about a specific number, the decoder strips away the mystery by revealing the manufacturer, the device model, and the reporting body that authorized it.
File Upload for Batch Processing
Streamline your workflow by uploading .txt or .csv files for immediate processing. The validator scans your documents, isolates every 15-digit sequence, and runs a full battery of checks to confirm validity. Once the scan is done, you can explore the results in a sortable table and export everything back to a clean CSV for your reports.
Bulk Generation up to 1,000 Numbers
Need a large set of data fast? The bulk engine can spin up to 1,000 unique, valid IMEIs in seconds. You have full control over the manufacturer mix, allowing you to target specific brands or create a diverse dataset. Your new batch comes ready for export as a detailed CSV, making it easy to populate databases or fuel automated testing scripts.
Free IMEI Generator for Developers and QA Engineers
Building and testing mobile applications often requires a steady supply of valid identifiers. This tool gives you structurally perfect IMEIs without the hassle of sourcing real hardware or worrying about privacy. Since everything runs locally in your browser, there are no accounts, API keys, or usage caps; just get the data you need and get back to coding.
Client-Side Processing for Complete Privacy
Your privacy is a priority, which is why every calculation stays inside your browser window. No data ever crosses the network or touches any server, ensuring your work remains confidential. This local-only approach makes the tool a safe choice for corporate environments or sensitive projects where data security is a top requirement.
Disclaimer and Intended Use
These generated numbers are for testing, development, and educational use only. Attempting to use these identifiers for fraud, bypassing carrier locks, or impersonating real hardware is strictly prohibited and illegal in many regions. The TAC prefix data is provided as a reference based on public records. No data is stored or transmitted by this tool.
