IMEI vs MEID: What’s the Difference?
When checking phone identifiers, you may encounter two different numbers: IMEI and MEID.
Both are used to identify mobile devices, but they come from different network technologies.
Understanding the difference between IMEI and MEID can help you verify a phone before buying or selling it.
What Is an IMEI Number?
IMEI stands for International Mobile Equipment Identity.
It is a unique 15-digit number assigned to most mobile phones around the world.
IMEI numbers are mainly used by GSM networks, which include many major carriers globally.
IMEI numbers are used for:
- Identifying phones on mobile networks
- Checking blacklist status
- Detecting stolen devices
- Verifying phone information
What Is a MEID Number?
MEID stands for Mobile Equipment Identifier.
It is similar to an IMEI but was originally created for CDMA networks.
CDMA networks were commonly used by carriers such as Verizon and Sprint in the United States.
Unlike IMEI numbers, MEID codes are usually 14 hexadecimal characters instead of 15 digits.
