Montenegro Postal Code validator
How the postal code format works
- Format
- 5 digits
- Example
- 81000
Things to watch for
- Format-only check — does not confirm the postal code actually exists
- Always exactly 5 digits with no separators
- Kept the Yugoslav-era 8xxxx numbering block after becoming independent in 2006 — Podgorica is still 81000
^[0-9]{5}$A Montenegrin postal code is the 5-digit code Pošta Crne Gore uses to route mail — for example 81000 for Podgorica. Montenegro was the last Yugoslav republic to become fully independent, in 2006, and rather than issue a new numbering scheme at that point it simply kept the 8xxxx code block the region had carried since 1971 — Podgorica’s code predates the country’s current name, since the city was still called Titograd when 81000 was first assigned. Anyone validating a Montenegrin shipping address, a checkout form, or a spreadsheet of customer records needs the code in the right 5-digit shape before it’s trusted.
Because it’s a bare run of digits with no separator, a transposed digit produces a code that still looks entirely plausible, with nothing about its shape flagging the mistake.
How this validator works
This tool checks that the input is exactly 5 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 postal code here carries no check digit, so matching the 5-digit shape is the most a client-side tool can confirm — not that it’s been assigned to a real town. Confirming that requires Pošta Crne Gore’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.
postal code FAQ
Why does Montenegro's postal code start with 8?
Montenegro kept the Yugoslav-era numbering block it was assigned in 1971 — codes starting with 8 — even after becoming fully independent in 2006. Podgorica, the capital, is 81000, the same code it carried as Titograd decades earlier.
What is Podgorica's postal code?
81000, for the city center.
Does a correctly formatted postal code mean it actually exists?
No. This tool only confirms the string is 5 digits — it doesn't check it against Pošta Crne Gore's actual assignment list. Confirming a code is real, and seeing which town it names, requires Pošta Crne Gore's own postcode lookup.
