# Permanent Equipment Identifier (PEI) of a 5G network (`pei`)

> **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.

Permanent identifier of the device that accesses a 5G core network (3GPP TS 23.003). The service APIs of the 5G core (3GPP TS 29.571) write it as imei- followed by an IMEI, imeisv- followed by an IMEISV, or, for devices on wireline access, mac- or eui- followed by a MAC address or an EUI-64 in hyphen-separated octets.

- 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`):

```
^(?:imei-\d{15}|imeisv-\d{16}|mac(?:-[0-9a-fA-F]{2}){6}(?:-untrusted)?|eui(?:-[0-9a-fA-F]{2}){8})$
```

## Examples

- `imei-490154203237518` — PEI of type IMEI
- `imeisv-3520990017614823` — PEI of type IMEISV
- `mac-00-1b-44-11-3a-b7` — PEI of type MAC address
- `490154203237518` (invalid example) — A bare IMEI without the type prefix

## Translations

- ru: Постоянный идентификатор оборудования (PEI) в сети 5G: Постоянный идентификатор устройства, подключающегося к ядру сети 5G (3GPP TS 23.003). В сервисных API ядра 5G записывается как imei- и IMEI, imeisv- и IMEISV, а для проводного доступа — mac- или eui- и MAC-адрес или EUI-64 по октетам через дефис.
