# IMDb ID (`imdb_id`)

> **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.

Identifier of a page in the Internet Movie Database: a two-letter prefix and seven or eight digits. tt is a title (film, series, episode or game), nm a person or group, co a company, ev an event, ch a character and ni a news item. An event edition adds the year, as in ev0000003/2015. Some datasets store title IDs without the tt prefix, as the digits only (MovieLens writes 0114709 for tt0114709); the regexp does not accept that form.
