What is an IMEI?
IMEI (International Mobile Equipment Identity) is a unique 15-digit number assigned to every mobile device. It's used by carriers to identify valid devices and can be used to block stolen phones.
The structure:
- TAC (Type Allocation Code) — first 8 digits, identifies the device model
- Serial Number — next 6 digits, unique to each device
- Check Digit — last digit, calculated using the Luhn algorithm
Why Generate Random IMEIs?
If you're building:
- Mobile device management (MDM) software
- Telecom billing systems
- Phone tracking applications
- IMEI validation libraries
- QA test suites for mobile apps
You need valid IMEI numbers that:
- Pass Luhn algorithm validation
- Have realistic TAC codes
- Don't belong to real devices
The Tool
randomimei.com generates valid test IMEI numbers instantly:
- ✅ Luhn-valid check digits
- ✅ Real TAC codes from actual device manufacturers
- ✅ Brand-specific generation (Apple, Samsung, Xiaomi, Huawei, etc.)
- ✅ Bulk generation for database seeding
- ✅ Free, no signup
How the Luhn Algorithm Works for IMEI
IMEI: 3 5 2 0 9 9 0 0 1 7 6 1 4 8 ?
Step 1: Double every other digit (from right, excluding check digit)
3 10 2 0 9 18 0 0 1 14 6 2 4 16
Step 2: Sum digits (10→1+0=1, 18→1+8=9, etc.)
3+1+2+0+9+9+0+0+1+5+6+2+4+7 = 49
Step 3: Check digit = (10 - (49 mod 10)) mod 10 = 1
