What is a GRid?

The Global Release Identifier (GRid) is a standard for identifying digital releases of sound recordings. It was developed by the IFPI and is widely used across the music industry to track and manage digital assets throughout the supply chain.

Understanding the GRid Structure

A Global Release Identifier is a unique 18-character alphanumeric string. It is not just a random sequence but a structured code that provides specific information about the release.

01

Identifier Scheme

The first two characters represent the identifier scheme (currently "RE" for GRid).

02

Issuer Code

A five-character code assigned to the organization issuing the GRid (e.g., a record label).

03

Release Number

A ten-character unique number assigned by the issuer to a specific release.

04

Check Character

A single character calculated using the ISO 7064 Mod 37, 2 algorithm to ensure the code's integrity.

Why Validate GRids?

Accuracy is critical in the music metadata supply chain. Incorrect GRids can lead to distribution delays, royalty calculation errors, and fragmented release data.

Data Integrity

Ensure your metadata meets industry standards before delivery to DSPs.

Royalty Tracking

Valid identifiers are essential for accurate revenue collection and reporting.

Catalog Mgmt

Keep your internal databases clean and consistent across all releases.

Universal Sync

Sync releases seamlessly across different platforms and territories.
