Bulgaria пощенски код validator
How the пощенски код format works
- Format
- 4 digits
- Example
- 1000
Things to watch for
- Format-only check — does not confirm the pощенски код actually exists
- Always exactly 4 digits with no separators
- One of the shortest postcodes in the EU, alongside Hungary and Luxembourg
^[0-9]{4}$A Bulgarian postal code (пощенски код) is the 4-digit code Български пощи uses to route mail, written directly before the city name — for example 1000 Sofia. At just 4 digits it’s noticeably shorter than the 5- and 6-digit systems used by most of Bulgaria’s Balkan and eastern European neighbours, giving the country a compact national grid rather than fine street-level precision. Anyone validating a Bulgarian shipping address, a checkout form, or a spreadsheet of customer records needs the postal code in the right 4-digit shape before it’s trusted.
Because it’s a bare run of digits with no separator, a transposed or dropped digit produces a code that’s still superficially plausible — cheap to catch at the point of entry, more costly once mail has already been sorted to the wrong town.
How this validator works
This tool checks that the input is exactly 4 digits with no letters, spaces, or hyphens, entirely in your browser, with nothing sent to a server.
What a pass doesn’t tell you
A Bulgarian postal code carries no check digit, so matching the 4-digit shape is the most a client-side tool can confirm — not that it’s been assigned to a real town. Confirming that requires Bulgaria’s own postcode lookup.
Scope: this page and tool cover format validation only — not address lookup or confirming a postal code is currently in use.
пощенски код FAQ
How many digits does a Bulgarian postal code have?
4 digits, written directly before the city name — for example 1000 Sofia for the capital's central district. It's one of the shortest postcodes in the European Union, on par with Hungary and Luxembourg rather than the 5-digit codes common elsewhere in the region.
Why is Bulgaria's postcode shorter than most of its Balkan neighbours?
Neighbouring Serbia, Croatia, and Romania all use 5- or 6-digit codes, several inherited from or expanded past the old Yugoslav-era 5-digit system. Bulgaria's Български пощи instead kept a compact 4-digit scheme, trading fine-grained precision for a simpler national grid.
Does a correctly formatted postal code mean it actually exists?
No. This tool only confirms the string is 4 digits — it doesn't check it against Български пощи's actual assignment list. Confirming a postal code is real, and seeing which town it names, requires Bulgaria's own postcode lookup.
