About PermID

Every day, professionals deal with disorganized and non-standard data that requires difficult and costly efforts before it can be used. To address these challenges, LSEG offers the PermID initiative to provide a means for our clients, partners and the open community to seamlessly navigate our vast data offerings.

Our Permanent Identifier (PermID) is a machine readable identifier that provides a unique reference for data item. Unlike most identifiers, PermID provides comprehensive identification across a wide variety of entity types including organizations, instruments, funds, issuers and people. PermID never changes and is unambiguous, making it ideal as a reference identifier. PermID is also in the center of LSEG's own information model and knowledge graph.

PermID is intended to enable interoperability. As a part of our open strategy, we provide users with a set of descriptive metadata for each entity to facilitate disambiguation to PermID with or without explicit mapping. We also provide a set of tools for working with the PermID and our Information Model, which we will continue to update, build and administer.
