# Track By Number

> Fetch a track's catalog record by its tape and position.

Resolves a track by position: give it a tape and a track number, get the same catalog record that [track metadata](/apis/gateway/tracks/track-metadata) returns by address.

Track numbers are positions in the tape's Merkle tree, assigned in write order and never reused. That makes them a stable way to walk a tape from front to back: start at zero, count up, and every number below the tape's track count resolves to exactly one record. It's the natural endpoint for indexers and backup tools that process a tape in order and don't want to collect addresses first.

The response arrives in the SDK's binary encoding, so use an SDK method rather than `curl` ([conventions](/apis/gateway)).

From Rust, `get_track_by_number` resolves the same record from chain state ([Rust SDK](/sdks/rust#the-modules)).
