ISRC and IPI checker
Paste an ISRC or an IPI number to check it is shaped correctly. This checks the format only, not whether the code is registered, so a well-formed code can still be unassigned.
Pattern
CC-XXX-YY-NNNNN
Pattern
9 or 11 digits
The format check runs entirely in your browser. The optional ISRC lookup sends just that code to MusicBrainz to find the recording. IPI stays in your browser. To confirm a registration elsewhere, check with the issuing body, your PRO, or your distributor.
ISRC, in one line
Identifies a recording. Assigned per track, it follows the audio across every platform so plays are counted and paid to the right rights holder.
IPI, in one line
Identifies a person or company. Assigned by your PRO, it routes publishing royalties to songwriters, composers, and publishers worldwide.
Common questions
- What is an ISRC?
- An ISRC (International Standard Recording Code) is a unique ID for a specific sound recording or music video. It travels with the recording across platforms so streams and downloads are counted and paid correctly. The format is CC-XXX-YY-NNNNN: a country code, a registrant code, a two-digit year, and a five-digit designation.
- What is an IPI number?
- An IPI (Interested Party Information) number identifies a songwriter, composer, or publisher across performing-rights organizations worldwide. It is assigned through your PRO and is used to route publishing royalties to the right people. The IPI Name Number is usually 9 or 11 digits.
- Does a valid format mean the code is registered?
- Not on its own. The format check only confirms the shape. For an ISRC you can also run the optional lookup, which checks the open MusicBrainz database and shows the recording if it is known there — but MusicBrainz is not exhaustive, so a real code can still come back empty. There is no public database to look up an IPI, so that stays format-only.
- What is the difference between an ISRC and an ISWC?
- An ISRC identifies a recording, the specific audio file. An ISWC identifies the underlying musical work, the composition. A song can have one ISWC and many ISRCs, one for each recorded version.
