    Choose the correct source
    Use the Companies Registry's current e-Services Portal and its e-Search services. The former Cyber Search Centre workflow should not be treated as the current instructions. Select the record or document needed and check the applicable access rules.

    Where do I find a Hong Kong company's registration number?

    Every registered Hong Kong 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 Hong Kong Companies Registry record.

    Is a Hong Kong registration number the same as a VAT number?

    No. The registration number is the identifier issued by the Hong Kong Companies Registry 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.
