Before invoicing an intra-Community supply without VAT, the law requires you to check that the buyer has a valid VAT number in their country. The check here is performed directly in VIES, the European Commission's register, and returns the name and address when the country provides them.
For a Bulgarian number, enter the UIC (9 digits) or UCN/PNC (10 digits) without BG at the beginning. This is the same check we automate in the invoicing and ERP systems we build.
- VIES confirms whether the number is valid at the time of the check. An invalid number may mean that the company is not VAT-registered, not that it does not exist.
- Germany, Spain and some other countries do not return a name and address. In that case, you will see only "valid" and the date of the check.
- If a country's register is down, VIES returns an error. Try again in a few minutes.
Questions and answers
VIES (VAT Information Exchange System) is the European Commission's system that queries national VAT registers to check whether a number is valid. It does not keep a separate database: it forwards the request to the country associated with the number.
BG plus the company's UIC (9 digits) or the individual's UCN/PNC (10 digits). For example, BG123456789. Do not enter the BG prefix in the number field.
Yes. For an intra-Community supply, a condition for applying the zero rate is that the recipient has a valid VAT number in another Member State. Keep proof of the check: the date and result.
Some countries, such as Germany and Spain, do not provide a name and address because of their data protection rules. The number is valid, the details are simply not displayed.
A UIC is checked in the Commercial Register (registryagency.bg). VIES only confirms whether the company is VAT-registered. A company with a UIC but without VAT registration will appear as invalid here.
Yes. In the ERP and invoicing systems we build, the number is checked when a new business partner is added and the result is saved with their record. Contact us if you use another system and want this check added.
