UEN or “Unique Entity Number”

Is a unique identifier issued to a Singapore entity upon incorporation or registration and also used as a standard identification number for Singapore entities to interact with government agencies.

Individuals will not be issued with a UEN. They will interact with government agencies using their NRIC or ID numbers or SingPass if they are Singapore IC holders. To minimise adoption costs and disruptions, the ACRA Registration Number is retained as the UEN mainly for businesses and companies as they comprise more than 85% of all entities registered in Singapore.

ACRA is the UEN System Administrator. Its role is to:

  • oversee the operation of UEN System
  • administer the issuance of UEN
  • assist agencies in handling queries on UEN
