Special UEN

Special UEN (SUN): Choose Your Preferred UEN

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.

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.

Types of SUN

Entity owners who would like to apply for the SUN service can choose their preferred UENs through two tiers as follows:

Tier 1

  • Fee: S$3,000 per SUN
  • SUN is defined as number with consecutive same number, or any number combination involving the number ‘8’

Tier 2

  • Fee: S$1,000 per SUN
  • SUN is defined as number with repetitive pattern (excluding the number ‘8’), or ending with triple identical number (such as ‘222’, ‘666’, ‘777’)

Examples of SUN under each tier:
