# International Standard Audiovisual Number (ISAN) (`isan`)

> **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.

ISO 15706 identifier of audiovisual works, such as films and episodes. It is hexadecimal: a 12-digit root and a 4-digit episode or part, an optional check character, then optionally an 8-digit version and a second check character. The check characters use ISO 7064 mod 37,36. Wikidata sometimes stores only the 12-digit root, such as 0000-0005-9DBA; the regexp does not accept it.

```
^(?:ISAN )?[0-9A-F]{4}-?[0-9A-F]{4}-?[0-9A-F]{4}-?[0-9A-F]{4}(?:-?[0-9A-Z])?(?:-?[0-9A-F]{4}-?[0-9A-F]{4}(?:-?[0-9A-Z])?)?$
```

## Examples

- `0000-0000-9E64-0000-9-AA55-2C14-M` — Synthetic number with a valid check digit
- `0000-0000-2279-0000-M-B381-1B6A-3` — Synthetic number with a valid check digit
- `0000-0000-2435-0000-2-0000-0000-V` — Toy Story
