Not sure where to find your company registration number? Get country-specific guidance on locating your business registration details, so your business check passes on the first try.
1. What a registration number is (and is not)
Your company registration number is the unique number your business received when it was officially registered with a government authority or business registry. It is different from your tax number, VAT number, or business license/permit number, even if they sometimes look similar.
You should be able to search this number in a public government business registry and find your company’s record.
If you enter a number in the form and cannot find your company with it on your government’s business registry website, it is probably the wrong number.
2. General steps (any country)
- Go to your government’s official business registry website (search “[your country] business registry” if needed).
- Search for your company by name
- Find the main registration number on that page or on your certificate of incorporation.
- Enter that number in the GetYourGuide verification form.
Common mistakes: using a VAT number, using a personal tax ID, adding or removing spaces or characters, or leaving out prefix letters like HRB or KVK.
