Device models supported
IMEIs generated to date
Luhn-algorithm validated
No registration required
Our IMEI number generator produces format-valid, Luhn-verified results in under one second — no account, no captcha, no waiting.
Choose from Apple, Samsung, Google, Xiaomi, Motorola, and 40+ other brands. Leave it blank for a fully random IMEI from any registered TAC prefix. You can also specify the exact model for brand-accurate TAC codes. Each brand in our free IMEI generator is mapped to its correct GSMA-registered Type Allocation Code, so every result reflects a real device family.
Enter how many IMEI numbers you need, from 1 to 10,000, and click Generate. Each number is built using a real registered TAC prefix combined with a randomised serial segment, then validated with the Luhn algorithm. Results are automatically deduplicated so you never receive the same number twice in a single batch.
Click any IMEI to copy it individually, use Copy All for the full set, or download a CSV for direct import into your test suite, mock database, or inventory system. If you need to convert between formats, our IMEI to serial number converter and serial number to IMEI converter are also available for free.
Every brand uses its own registered TAC (Type Allocation Code) prefix. Our database maps 50,000+ TAC codes to the correct brand and model so your generated IMEI reflects the real device family.
iPhone 14 through iPhone 16 Pro Max. Apple IMEI numbers use TAC prefixes registered by Foxconn and Pegatron. Our tool supports all current and legacy iPhone models from iPhone 5 onwards. Once you have finished generating test IMEIs for iPhone, you can also check a real device using our iPhone IMEI check tool.
Galaxy S24 Ultra through Galaxy A and M series. Samsung registers TAC codes by production region, so a Korean and a US Galaxy S24 carry different prefixes. Our free IMEI generator accounts for both regional variants. If you are working with a locked Samsung device, visit our Samsung unlock page for carrier-specific unlock options.
Pixel 6 through Pixel 9 Pro. Google self-designs and contract-manufactures its Pixel range. TAC codes are registered to Google LLC directly and are distinct from the Android reference hardware set. For unlocking a carrier-locked Pixel, see our Google Pixel AT&T unlock service.
Xiaomi 14 series, Redmi Note 13 series, and POCO X6. Xiaomi products ship under multiple brand registrations. Our database includes Xiaomi Inc., Redmi, and POCO TAC entries separately. For factory unlock services on Xiaomi devices, see our Xiaomi unlock page.
Every feature is designed for professionals who need reliable, accurate IMEI data — not just a random 15-digit string.
Every IMEI starts with a genuine, GSMA-registered Type Allocation Code. This means the brand and model section of the IMEI is accurate, which is critical for any test that parses the TAC to identify device type. You can verify detailed specs for any IMEI using our IMEI full device specification lookup.
The 15th check digit is always calculated using the Luhn algorithm (ISO/IEC 7812), so every IMEI passes format validation. Apps that verify IMEI structure before processing will accept every number we generate. For a deeper look at how IMEI validation works, see our IMEI calculator details page.
Generate up to 10,000 unique random IMEI numbers in a single click. Results are deduplicated — you never receive the same number twice in a batch, which matters for realistic simulation datasets.
Download your full batch as a .csv file, ready to import directly into your test framework, mock API, app configuration, or inventory management system — no reformatting required.
All IMEI generation happens in your browser. We do not store, log, or transmit the numbers we generate. Your test data stays private.
From the latest iPhone 16 Pro Max to legacy Android handsets, our TAC database covers 50,000+ device models across 45+ brands — updated quarterly against the GSMA's official registry.
A random IMEI number is a synthetic 15-digit identifier that follows the same structural rules as a real device IMEI but is not registered to any physical handset. It looks like a real IMEI, passes format checks, and carries a legitimate brand TAC — but it exists only in software.
The reason validity matters is simple: most software that processes IMEI numbers runs a format check before doing anything else. A system that receives a string of 15 random digits will reject it immediately if the Luhn check fails. By generating valid random IMEI numbers, you ensure your tests actually reach the code paths you're trying to exercise.
Developers use random IMEI numbers to populate test databases, simulate multi-device environments, and test device-specific API responses, all without tying tests to the IMEI of a physical device they may not have on hand. For a full explanation of what IMEI unlocking means in the real world, read our blog post on what is IMEI unlock.
The IMEI standard is defined by the GSMA (Global System for Mobile Communications Association) and standardised under ITU-T E.212. Every legitimate IMEI contains: an 8-digit Type Allocation Code (TAC), a 6-digit serial number, and a 1-digit Luhn check digit.
TAC, serial, and the final check digit combine to create a format-valid 15-digit IMEI.
Identifies the registered device family and allocation block.
Creates variation inside the same device family range.
Completes Luhn validation so the IMEI passes format checks.
Double every second digit from the right. Starting from the rightmost digit (excluding the check digit), double every alternate digit.
Subtract 9 from any doubled value above 9. If doubling produces a two-digit number (e.g. 7 × 2 = 14), subtract 9 to get a single digit (14 − 9 = 5).
Sum all resulting digits. Add the untouched digits and all the doubled (and adjusted) digits together.
The check digit makes the total divisible by 10. Choose the digit (0–9) that brings the grand total to the next multiple of 10 — this is the 15th digit of every valid IMEI.
Our free random IMEI generator is built for professionals who need accurate, realistic device identifiers for legitimate technical work.
Test device-specific code paths including push notification delivery, device analytics events, or hardware feature detection, without relying on a real device's IMEI. Generate brand-specific IMEIs to simulate iOS versus Android behaviour, or Pixel versus Galaxy differences, in your CI environment. Once development is complete, use our unlock eligibility check to verify real test devices are carrier-free before deploying.
Verify that your device management software, point-of-sale system, or repair-tracking platform correctly parses and stores IMEI input before going live with customer devices. Also useful for training staff on IMEI identification without exposing real customer data. When you do handle real locked devices in your shop, our network unlock apps page covers the full range of carrier unlock options available.
Populate mock device registration databases with thousands of realistic IMEIs to load-test device management platforms, mobile MDM systems, or carrier provisioning APIs. Brand-specific generation means your test data reflects real-world TAC distribution, not a homogeneous synthetic set.
Teaching network architecture, mobile standards, or cybersecurity? Generated IMEIs let students explore device identification concepts, practise IMEI validation implementations, and run exercises involving the Luhn algorithm, all with safe, synthetic data. Our blog post on how to find an IMEI number on any phone is a useful companion resource for teaching the basics.
These three sections are designed to fit naturally into the IMEI Generator flow, combining real-device verification guidance, development use cases, and lawful usage notes in the same visual language as the rest of the page.
Generated IMEIs are intended exclusively for testing and simulation. If you are working with a real device and need to verify its status, EasySimUnlocker provides a full suite of free IMEI check tools. Use the iPhone IMEI carrier lock check to confirm whether a device is still locked to a carrier, or the iPhone IMEI blacklist check to confirm it has not been reported lost or stolen. For warranty verification, the Apple warranty check tool returns current warranty status instantly using the device IMEI.
For devices that turn out to be carrier-locked, our free SIM unlock online service removes the lock permanently at the carrier database level. The process takes under three minutes and requires no payment. You can also run a full device history report using our iPhone GSX report tool, which returns activation history, Find My status, and warranty information in a single lookup.
Understanding the difference between a generated test IMEI and a real device IMEI is also worth reading about. Our blog post on what is the difference between SIM unlock and carrier unlock explains the underlying concepts clearly for both technical and non-technical readers.
Our bulk IMEI generator handles up to 10,000 numbers in a single export. For larger volumes or programmatic access, our API delivers IMEI generation at scale — with webhook support, format options, and rate limiting built in.

Building an analytics demo or training a device-classification model? Use our bulk IMEI generator to create a statistically realistic device dataset — with brand TAC distribution weighted to match real-world market share if needed.
One of the most common professional use cases for a free IMEI generator is mobile app development. Apps that collect device fingerprints, run device-specific logic, or integrate with carrier APIs need realistic test data to function properly during development and staging. A hardcoded real IMEI creates privacy and compliance risks. A purely random 15-digit number fails format validation before it reaches the code being tested.
Our free IMEI generator solves both problems. Every generated IMEI carries a legitimate TAC prefix that identifies a real device family, combined with a randomised serial segment that is unique within your batch. This means device-classification logic, analytics tagging, and hardware-feature detection all behave as they would with real device data, without any compliance risk..
For developers building apps that also interact with carrier lock status, our mobile IMEI status checker app provides a live status lookup that can be tested alongside your generated IMEI datasets. The EasySimUnlocker safe check tool is also available for verifying that any IMEI you plan to use in production checks is clean and not flagged.
Generated IMEI numbers are synthetic identifiers produced for lawful purposes only. Acceptable uses include software testing, QA simulation, mobile app development, repair technician training, academic education, and internal inventory seeding.
You must not use a generated IMEI to misrepresent a device's identity to a carrier, bypass network authentication, register a device under false pretences, or commit fraud of any kind. EasySimUnlocker does not store generated numbers and takes no responsibility for misuse.
