A Unique Entity Number (UEN) is an identification number that is generated for a business entity, following successful incorporation/registration with ACRA. All business entities need to use the UEN when transacting with government agencies. This UEN is issued free of charge to business entities.
From 9 February 2018, entity owners can choose, at a fee, a preferred UEN from a list of reserved UENs during entity incorporation/registration or conversion. This preferred UEN is known as Special UEN (SUN). Those who do not wish to apply for a SUN will continue to be issued with a free system-generated UEN. SUN enables entity owners to more easily identify with and remember their own UEN when transacting with government agencies.
How to Apply for SUN
Entity owners can apply for SUN at (a) the point of incorporating/registering an entity and (b) conversion to another entity type. The option to select a SUN is available at the payment stage for applicable transactions in BizFile+ (see examples below).
Example: Applying for SUN during incorporation/registration of an entity
Example: Applying for SUN during incorporation/registration of multiple entities
