Mongolia шуудангийн код validator
How the шуудангийн код format works
- Format
- 5 digits
- Example
- 14200
Things to watch for
- Format-only check — does not confirm the шуудангийн код actually exists
- Always exactly 5 digits with no separators
- Replaced the old ad hoc numbering under a 2008 reform — the digits encode aimag/city, district, and sub-district in sequence
^[0-9]{5}$A Mongolian шуудангийн код (postal code) is the 5-digit code Mongolia Post uses to route mail — for example 14200 for an Ulaanbaatar address. It’s a relatively young system: Mongolia introduced structured digital postcodes under a reform starting in 2008, replacing an older, far less consistent numbering approach with one where each digit position carries real geographic meaning — aimag or capital first, then district, then sub-district. Anyone validating a Mongolian 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 in the leading pair can silently misroute an address to a different aimag or district entirely, not just a different street.
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 шуудангийн код carries no check digit, so matching the 5-digit shape is the most a client-side tool can confirm — not that Mongolia Post has assigned it to a real district. Confirming that requires Mongolia Post’s own postcode lookup.
Scope: this page and tool cover format validation only — not address lookup or confirming a code is currently in use.
шуудангийн код FAQ
What do the digits of a Mongolian postal code mean?
Under the reform Mongolia Post rolled out from 2008, the 5 digits encode location in sequence: the first pair identifies the aimag (province) or capital city, the next identifies the district or soum, and the final digit narrows to a sub-district or bag — a structured hierarchy replacing the country's older ad hoc numbering.
What is Ulaanbaatar's postal code?
Ulaanbaatar addresses use codes in the 14000-15999 range depending on district — 14200 is a commonly cited example for the capital.
Does a correctly formatted шуудангийн код mean it actually exists?
No. This tool only confirms the string is 5 digits — it doesn't check it against Mongolia Post's actual assignment list. Confirming a code is real, and seeing which district it covers, requires Mongolia Post's own postcode lookup.
