# Highly Individualised Device Registration Identifier (HIDRI) (`hidri`)

> **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.

GS1 identification key for the registration of highly individualised medical devices. It is a GS1 Company Prefix, a reference and two check characters, up to 25 characters of GS1 character set 82 with at least one character that is not a digit; the check pair is computed as for the Global Model Number. Application Identifier (8014), data title MUDI, carries it next to a GTIN in AI (01); the element string is the pattern gs1_ai_8014.

- Personal data (PII): no
- Categories: GS1 standards (gs1), Objects identifiers (objectids), Medical/pharma identifiers (medical)
- Countries: global
- Languages: Common to most languages (common)
- Classification: identifier
- Patterns: `gs1_ai_8014`

## Detection

Regular expression (Python `re`):

```
^(?=.*[^0-9])\d{4}[!%-?A-Z_a-z\x22]{0,19}[2-9A-HJ-NP-Z]{2}$
```

Check digit algorithm: `gs1_checkpair`

## Examples

- `9528765LENS-0042F6` — Synthetic value with the GS1 demonstration prefix 952 and a valid check character pair
- `9528765SPEC-L71ER` — Synthetic value with the GS1 demonstration prefix 952 and a valid check character pair
- `9528765LENS-004222` (invalid example) — Check characters changed: fails the check pair
