UEN (Unique Entity Number)
The single identifier every entity registered in Singapore has — companies, sole proprietorships, societies and government bodies alike. It is what identifies a business across government agencies and across most commercial onboarding, and it is the first field on almost every merchant application.
Why it matters to a merchant
The single fastest thing you can do to shorten an application is have this correct and to hand, along with the ACRA profile it appears on. It is also worth checking that the entity behind your UEN is the entity whose name you trade under — where those differ, every downstream document will ask about it, and knowing the answer in advance turns a week into an afternoon.
