Concept Comparisons
IMEI vs MEID: Which Code Should You Use?
IMEI (GSM/LTE/5G) differs from MEID (CDMA) in format and purpose — Apple checks prefer the serial.
Comparison table
| IMEI | MEID | |
|---|---|---|
| Network | GSM / LTE / 5G | CDMA |
| Format | 15 digits | 14 hex |
| Check digit | Luhn | Different standard |
| Modern devices | Common | Rare |
| Apple Coverage | Not primary | No |
When do you still see a MEID?
Older US / CDMA-market iPhones may show both a MEID and an IMEI in About. Modern units mostly emphasize the IMEI.
Practical recommendation
- Apple warranty check → serial.
- Box / Settings cross-check → IMEI (and IMEI 2 if present).
- Use the MEID only when the counterparty asks for it.
How to store it in Excel
For modern lots, the important columns are serial and IMEI. Keep a MEID column only if your warehouse still takes legacy CDMA units.
Quick decision checklist
- Decide whether you need an IMEI or a serial.
- Pick the right lookup (Apple Coverage vs carrier vs Find My).
- Match model/box before concluding.
- For lots: export Excel and bulk-check.
When pricing used devices: Coverage shows remaining warranty days; Activation Lock decides whether the unit is usable after erase; blacklist (if your market uses one) decides cellular attach. These layers do not replace each other.
Summary
These two concepts are often mixed up in deals. Keep the definitions straight and you will pick the right code and read results correctly.
