DPID

DPID stands for DDEX Party Identifier. It is the DDEX Party Identifier that uniquely identifies each sender and receiver of a DDEX formatted message.

A DPID (Data Provider Identifier) is a unique identifier assigned by DDEX to organizations that participate in data exchange within the digital music supply chain. Any company that sends or receives DDEX-formatted messages — distributors, DSPs, labels, PROs, and other data providers — is assigned a DPID that uniquely identifies them in every transaction they participate in.

DPIDs serve as the organizational equivalent of an ISRC (for recordings) or UPC (for releases) — they are the identifier that says who is sending or receiving a given data message. When a distributor delivers a release to a DSP via an ERN (Electronic Release Notification Message), the DPID of the sending distributor and the DPID of the receiving DSP are included in the message header. This allows automated systems to validate the source and destination of every transaction and maintain a reliable audit trail.

Organizations obtain DPIDs by joining the DDEX standards consortium and registering. Major DSPs like Spotify, Apple Music, and Amazon Music all have DPIDs, as do large distributors and aggregators. Smaller companies or those who participate in DDEX exchange through a larger partner may use their parent organization's DPID.

For independent artists and small labels, DPIDs are largely invisible — they are used by the distributor on behalf of their clients. However, understanding that DPIDs exist explains why distributors must be registered DDEX participants to deliver to major DSPs, and why not every aggregator has the same reach or technical capability.

melabel operates as a registered data provider in the DDEX ecosystem, enabling it to deliver releases to all major DSPs using standardized, validated DDEX message formats on behalf of its artists and labels.
