    Where do I find a Singapore company's registration number?

    Every registered Singapore entity has a unique registration number issued at incorporation. It appears on invoices, contracts, the company's website footer (often in a "legal" section), and prominently on its ACRA / BizFile+ record.

    Is a Singapore registration number the same as a VAT number?

    No. The registration number is the identifier issued by the ACRA / BizFile+ when the company was formed. The VAT number is a separate tax identifier issued (only if the company is VAT-registered) by the national tax authority. Many small companies have a registration number but no VAT number.
