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

    Use the exact UEN with its issuing jurisdiction or register on ACRA. Compare the returned legal name and identifier. A valid-looking number does not guarantee a result: coverage, formatting, access and source availability affect the lookup.

    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

      Preserve leading zeros, letters, court and jurisdiction information. Follow the source's documented format rather than removing meaningful parts to force a match.

    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.

    Frequently asked questions

    What is a UEN in Singapore?

    It is the identifier ACRA assigns to a registered entity. It stays with the entity even if the trading name changes, which makes it the reliable way to track a company over time.

    Is a UEN lookup free?

    LemReveal's basic lookup is free where supported. Check ACRA's official access rules for the record or document required.

    What if the UEN returns no result?

    Check the format, issuing jurisdiction, coverage and source availability. Preserve meaningful prefixes and leading zeros. An unavailable source is not a confirmed absence; ask the counterparty to clarify the identifier.

    Should I use the UEN or the company name?

    The UEN. Names are duplicated across entities within a group; the number is unique to one entity.

    What is a UEN?

    UEN (Unique Entity Number) is a standard identification number for all entities registered in Singapore. It's a 9 or 10-character alphanumeric code used for all government transactions. Format: XXXXXXXXX for businesses, TXXYYXXXXL for local companies.
