Cambodia Postal Code validator
How the postal code format works
- Format
- 6 digits
- Example
- 120101
Things to watch for
- Format-only check — does not confirm the postal code actually exists
- Always exactly 6 digits with no separators
- Cambodia upgraded from an older 5-digit code to a 6-digit system in recent years; the first two digits mark the province, so Phnom Penh addresses start with 12
^[0-9]{6}$A Cambodian postal code is the 6-digit code that replaced an older 5-digit system — for example 120101 for a central Phnom Penh address. Because the upgrade is relatively recent, older records, address books, or forms copied from before the switch may still carry a 5-digit code that no longer matches the current standard, making a length check a useful way to flag stale entries. Anyone validating a Cambodian shipping address, checkout form, or spreadsheet of customer records needs the current 6-digit code before it’s trusted.
Because the code is a bare 6-digit run with no separator, a leftover 5-digit code from before the change can look almost right while still being the wrong length under the current system.
How this validator works
This tool checks that the input is exactly 6 digits with no letters, spaces, or hyphens, entirely in your browser — nothing is sent to a server, and there’s no signup.
What a pass doesn’t tell you
A Cambodian postal code carries no check digit, so matching the 6-digit shape is the most a client-side tool can confirm — not that it’s been assigned to a real commune or village. Confirming that requires Cambodia Post’s own postal code lookup.
Scope: this page and tool cover postal code format validation only — not address lookup, province matching, or confirming a code is currently in use.
postal code FAQ
Why did Cambodia's postal code change length?
Cambodia originally used a 5-digit system, but upgraded to the current 6-digit format in recent years under the Ministry of Posts and Telecommunications, adding a digit of precision as the country's addressing needs grew.
What do the digits of a Cambodian postal code encode?
The first two digits identify the province — 12 for Phnom Penh — and the remaining four step down through district, commune, and village-level detail.
Does a correctly formatted postal code mean it actually exists?
No. This tool only confirms the string is 6 digits — it doesn't check it against Cambodia's actual postal assignment list. Confirming a code is real requires Cambodia Post's own lookup.
