IMEI and MEID are device identifiers used in mobile networks, but they come from different technical histories and are formatted differently.
What IMEI identifies
IMEI stands for International Mobile Equipment Identity and normally appears as a 15-digit identifier for cellular equipment.
What MEID identifies
MEID stands for Mobile Equipment Identifier and is associated historically with CDMA-based equipment identification.
Why both may appear
Some devices, repair records and carrier databases may display more than one equipment identifier because devices support multiple network technologies.
Where to find them
Check Settings, the retail box, the invoice, operator records and the dial code *#06# where supported.
Do not copy a SIM ICCID or serial number by mistake.
Why this matters when buying used
A buyer should compare all available identifiers and investigate mismatches before payment.
Keep an ownership record
Save identifiers with the invoice, serial number, purchase date and seller details. Use IMEI Alert owner registration where appropriate.
Frequently asked questions
Is MEID the same as IMEI?
No. They are different equipment identifiers with different formats and histories.
Do modern phones still use MEID?
Some devices and records may still show MEID, especially in legacy CDMA contexts.
Which identifier should I record?
Record every identifier shown by the device and trusted purchase documents.
Can one phone show both?
Yes, depending on hardware and network support.
Is either one a password?
No. They identify equipment and should still be handled carefully.
