Bulgarian VAT number check
Check a Bulgarian supplier's or customer's number against VIES, the European Commission's register. Below: the format, what it's called locally, and the mistakes that make a correct number fail.
Paste the number with or without the country prefix. Nothing you enter is stored.
The format
| Prefix | BG |
|---|---|
| After the prefix | 9 or 10 digits |
| Structure | One block of 9 digits or one block of 10 digits. |
| Examples | BG123456789 or BG1234567890 |
You can paste the number with spaces, dots or dashes; the checker removes them.
What it's called
Идентификационен номер по ДДС (identification number for VAT, the DDS number).
For companies, the VAT number is BG followed by the unified identification code (ЕИК / UIC) from the Commercial Register or BULSTAT.
What trips people up
- Individuals' VAT numbers used to be BG plus their personal ID number. The NRA has been replacing these (BULSTAT-registered individuals from October 2022, others from January 2024), so older supplier records may hold a number that has changed.
Other ways to check
VIES is the check to rely on for cross-border trade. The number is issued by National Revenue Agency (НАП / NRA); if a correct number keeps showing invalid, the business has to take it up with them.
