Nepal Postal Code validator
How the postal code format works
- Format
- 5 digits
- Example
- 44600
Things to watch for
- Format-only check — does not confirm the postal code actually exists
- Always exactly 5 digits with no separators
- Kathmandu GPO's code, 44600, is the postal code most commonly printed on Nepali addresses
^[0-9]{5}$A Nepali postal code is the 5-digit code Nepal Post uses to route mail — for example 44600 for Kathmandu. Unlike some neighboring systems that pack a lot of routing meaning into the leading digits, Nepal’s codes are assigned per district and don’t follow as tight a geographic hierarchy, so the digits alone won’t tell a reader which part of the country a code belongs to without a lookup. Anyone validating a Nepali shipping address, a checkout form, or a spreadsheet of customer records still 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 single transposed pair produces a code that looks just as plausible as the real one, 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 Nepali postal code carries no check digit, so matching the 5-digit shape is the most a client-side tool can confirm — not that Nepal Post has assigned it to a real district. Confirming that requires Nepal Post’s own postcode directory.
Scope: this page and tool cover format validation only — not address lookup or confirming a postal code is currently in use.
postal code FAQ
What is Kathmandu's postal code?
44600 — the code most commonly printed on Nepali addresses and the one most people mean when they say 'Kathmandu postal code,' referring to the GPO in the capital.
How many digits does a Nepali postal code have?
Five, written as a plain run of digits with no separator.
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 Nepal Post's actual assignment list. Confirming a postal code is real, and seeing which town it names, requires Nepal Post's own postcode directory.
