# Add External IDs

TMDB allows editors to **link titles with external databases** such as IMDb, TVDB, and Wikidata ensuring proper synchronization and data accuracy across multiple services like SIMKL.

These external links (called **Connected IDs**) are essential for metadata exchange and for keeping related movie and TV entries correctly associated across platforms.

### For TV Shows

When editing a **TV show**, an additional field appears under “Other Databases” for:\
**TVDB ID:** connects TMDB entries with TheTVDB’s corresponding listing.

This field is especially important for synchronization tools (like SIMKL, Plex) that use both databases to match TV episodes.
