A rejected Tax Identification Number (TIN) almost always comes down to one of five causes: a typo, the wrong number type, a country mismatch, a profile mismatch, or an outdated number. Here is how to identify and fix each one.
1. Typo or wrong format
The most common cause. Each country's TIN has a fixed structure (for example, 9 digits in Portugal, 11 digits in Germany, 16 characters in Italy), and our system validates it automatically.
Fix: Compare what you typed against your official document, character by character. Check the expected format in our article Where do I find my Tax Identification Number (TIN)?. You can also test the structure yourself with the European Commission's TIN check tool.
2. You entered a document number instead of your TIN
ID cards and passports carry their own document numbers, which are not your tax number. Typical examples: the card number of a Portuguese Cartão de Cidadão instead of the NIF, the German Personalausweis number instead of the Steuer-IdNr, or the "support number" on a Spanish NIE card instead of the NIE itself.
Fix: Locate the correct number using the country table in Where do I find my Tax Identification Number (TIN)?.
3. Your TIN doesn't match your declared country of tax residence
The TIN you provide must be issued by the country you declared as your tax residence. This often happens after moving countries: you declare your new country but enter your old country's TIN, or the other way around.
Fix: Make sure both fields refer to the same country. If you have moved, see How do I update my tax residence after moving to another country?. If you are tax resident in several countries, declare each one with its own TIN.
4. Your details don't match your verified profile
We are required to check your self-certification against the identity information on your account. A name change (for example, after marriage), a different name spelling or transliteration, or an outdated date of birth can cause a mismatch.
Fix: Contact our support team so we can update your profile first. Have an official document ready that shows your current details.
5. Your number is outdated
Some numbers change with your circumstances. For example, if you obtained Spanish nationality, your NIE was replaced by a DNI. In Poland, which number applies (PESEL or NIP) depends on whether you run a registered business activity.
Fix: Submit your current number. If you are not sure which one applies, your tax authority can confirm it.
Still being rejected?
Contact our support team through the in-app chat or at support@venga.com with:
- A photo or screenshot of the official document showing your TIN (you can cover unrelated information)
- The country of tax residence you are declaring
We will review it manually and update your account.
Note: The automatic check validates the structure of the number. A TIN that passes the format check may still need manual review if it does not match the rest of your profile.
