The Unique Entity Number (UEN) is like the NRIC Number of your entity.
From 1 January 2009, all entities such as businesses, companies and societies that operate in Singapore can start interacting with government agencies using their UEN.
Singapore Customs will be implementing UEN, which will replace the Central Registration (CR) Number that you currently use to interact with Singapore Customs from January 2009.
