What Is MEID? Difference Between MEID and IMEI
MEID is the core identifier for CDMA devices. Learn what MEID is, how it works, and the key differences from IMEI so you can make the right decisions when verifying a device.
MEID Definition and Meaning
MEID (Mobile Equipment Identifier) is a device identification code used in CDMA (Code Division Multiple Access) network environments. It consists of 14 hexadecimal characters (digits 0-9 and letters A-F), defined by the TIA (Telecommunications Industry Association) standard, and uniquely identifies mobile devices on CDMA networks.
MEID was created during the CDMA era and was primarily used on devices from US carriers such as Verizon and Sprint. Its function is similar to IMEI in GSM networks — both serve as a device's "digital ID" — but the format and governing body differ due to the different network technologies.
MEID 14-Digit Hex Structure
The 14-character hexadecimal MEID has a structured format:
- First 8 digits (manufacturer code + serial segment): Licensed by TIA, identifies the device manufacturer and product model category.
- Last 6 digits (device serial segment): Assigned by the manufacturer to uniquely identify each unit within the same model.
- Check mechanism: MEID includes a validation check, though simpler than the Luhn algorithm used by IMEI.
MEID can also be represented as an 18-digit decimal form (called pMEID). However, the 14-digit hex format is the most widely used in everyday scenarios.
MEID vs IMEI: Key Differences
| Dimension | MEID | IMEI |
|---|---|---|
| Length | 14 digits (hex) | 15 digits (numeric) |
| Network | CDMA | GSM / UMTS / LTE / 5G |
| Governing Body | TIA | GSMA |
| Global Coverage | Limited (primarily US) | Global |
| Current Trend | Phasing out | Ongoing |
As mobile networks transition from CDMA to LTE and 5G, MEID usage is declining. Modern smartphones typically have both MEID and IMEI, but IMEI remains the more universal and reliable identifier for global queries.
Frequently Asked Questions
Q1: What does MEID stand for?
MEID stands for Mobile Equipment Identifier. It is a 14-character hex code used to identify devices on CDMA networks.
Q2: Is MEID the same as IMEI?
No. MEID is 14-digit hex (CDMA networks), IMEI is 15-digit numeric (GSM/global). Modern smartphones have both.
Q3: Which devices use MEID?
Primarily CDMA devices from US carriers like Verizon and Sprint. MEID usage is declining as CDMA networks retire.
Q4: Can I check MEID online?
Yes, IMEICheck supports MEID queries for device model and blacklist status checks.
Q5: How to find MEID on iPhone?
Settings → General → About → MEID. Also on the SIM tray and original packaging.
