How the cod poștal format works
- Format
- 6 digits
- Example
- 010101
Things to watch for
- Format-only check — does not confirm the cod poștal actually exists
- Always exactly 6 digits with no separators
- In Bucharest addresses the second digit is the sector number (1-6), e.g. 01xxxx for Sector 1
^[0-9]{6}$A Romanian cod poștal is the 6-digit postcode Poșta Română uses to route mail, replacing an older Communist-era system when the current numbering was introduced in 2003. The first digit marks one of ten broad postal regions and the second narrows to a county — inside Bucharest specifically, that second digit identifies one of the capital’s six numbered sectors directly, so 010101 names an address in Sector 1. Anyone validating a Romanian shipping address, a checkout form, or a spreadsheet of customer records needs the cod poștal in the correct 6-digit shape before it’s trusted.
Because it’s a bare 6-digit run with no separator, a single dropped or duplicated digit is easy to miss visually while still producing a code that looks entirely plausible.
How this validator works
This tool checks that the input is exactly 6 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 cod poștal carries no check digit, so matching the 6-digit shape is the most a client-side tool can confirm — not that Poșta Română has assigned it to a real street or building. Confirming that requires Poșta Română’s own postcode lookup.
Scope: this page and tool cover format validation only — not address lookup or confirming a cod poștal is currently in use.
cod poștal FAQ
How many digits does a Romanian cod poștal have, and what do they encode?
6 digits. The current system, introduced in 2003, uses the first digit for one of ten broad postal regions and the second for the county within it; the remaining four digits narrow things down to a locality, street, or building.
How does the cod poștal work inside Bucharest specifically?
Bucharest is split into six numbered sectors, and the second digit of the code identifies the sector directly — 01xxxx for Sector 1, 03xxxx for Sector 3, and so on up to Sector 6.
Does a correctly formatted cod poștal mean it actually exists?
No. This tool only confirms the string is 6 digits — it doesn't check it against Poșta Română's actual assignment list. Confirming a cod poștal is real, and seeing which street it covers, requires Poșta Română's own postcode lookup.
