    How do I look up a company by its registration number in Singapore?

    Enter the UEN to look up a Singapore company directly on ACRA. Unlike a name search, an UEN returns exactly one entity, which is why it is the identifier to use for KYC, invoicing and contract checks.

    Step-by-step

    1. 1

      Find the UEN on the paperwork

      The UEN normally appears on invoices, contracts, the website footer or official correspondence. It is the number counterparties are required to quote.

    2. 2

      Search the UEN

      Enter the number exactly as printed. Punctuation and spacing vary between documents — strip them if the search returns nothing.

    3. 3

      Confirm the returned entity

      Check the legal name on the returned record matches the name on your paperwork. A mismatch between quoted number and quoted name is a serious warning sign.

    4. 4

      Verify at ACRA

      For anything contractual, confirm the number against the primary source at https://www.acra.gov.sg.
