Colombia código postal validator
How the código postal format works
- Format
- 6 digits
- Example
- 110111
Things to watch for
- Format-only check — does not confirm the código postal actually exists
- Always exactly 6 digits with no separators
- Introduced nationwide in 2009 (Colombia had no unified postal code before then); the first two digits are DANE's department number and the third and fourth mark the postal zone within it
^[0-9]{6}$A Colombian código postal is the 6-digit address code Colombia adopted nationwide in 2009, replacing decades of having no consistent postal-code system at all — for example 110111 for a central Bogotá address. Because the code is built hierarchically from a DANE department number down through postal zone and district, a single wrong digit anywhere in the string can misroute mail to an entirely different part of the country rather than just a nearby block. Anyone validating a Colombian shipping address, checkout form, or spreadsheet of customer records needs the full 6 digits correct before it’s trusted.
Because the code is a bare run of digits with no separator, a code copied from an older 4- or 5-digit foreign format, or one missing a leading zero from its zone segment, can slip through unnoticed without a length check at the point of entry.
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 código postal carries no check digit, so confirming it’s 6 digits long is the most a client-side tool can do — not that Colombia’s postal service has assigned it to a real department, zone, and district. Confirming that requires Colombia’s own postal code lookup.
Scope: this page and tool cover código postal format validation only — not address lookup, department/zone matching, or delivery confirmation.
código postal FAQ
How many digits does a Colombian postal code have?
Always 6 — for example 110111 for a central Bogotá address. Colombia had no unified nationwide postal code system before 2009, so any code shorter than 6 digits predates the current standard and isn't valid under it.
What do the digits in a Colombian código postal mean?
The first two digits are DANE's official department number (11 for Bogotá D.C.), the third and fourth mark a postal zone within that department — 00 is reserved for the department capital — and the last two narrow it to one of up to 100 postal districts inside that zone.
Does a correctly formatted código postal mean it actually exists?
No. This tool only confirms the string is 6 digits — it doesn't check it against Colombia's actual postal assignment list. Confirming a code is real requires Servicios Postales Nacionales' own lookup tool.
