# Mobile Equipment Identifier (MEID) (`meid`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

56-bit identifier of CDMA mobile devices that replaced the 32-bit ESN (esn). It is written as 14 hexadecimal characters or as an 18-digit decimal number, either of them optionally followed by a check character.

- Personal data (PII): yes
- Categories: Telecommunications (telecom), Personally identifiable information (pii)
- Countries: global
- Languages: Common to most languages (common)
- Classification: identifier

## Detection

Regular expression (Python `re`):

```
^(?:[0-9A-F]{14}[0-9A-F]?|\d{18}\d?)$
```

## Examples

- `AF0123450ABCDE` — Hexadecimal form (python-stdnum documentation)
- `AF0123450ABCDEC` — The same MEID with its check character C
- `293608736500703710` — The same MEID in decimal form
- `2936087365007037100` — Decimal form with its check digit 0
- `AF0123450ABCD` (invalid example) — One character too few
