Ecuador código postal validator

An Ecuadorian código postal is the 6-digit code Correos del Ecuador uses to route mail — for example 170401 for Centro Histórico, Quito. The structure is hierarchical by design: the first two digits fix the province, the next two the canton, and the last two a zone within it, so every code in Pichincha province starts with 17 regardless of which city or town it belongs to. Anyone validating an Ecuadorian shipping address, checkout form, or spreadsheet of customer records needs the código postal to be the right length and shape before it’s trusted.

Because the code is a bare 6-digit run with no separator, a code with a transposed digit pair still produces a plausible-looking province prefix, which is exactly the kind of error a shape check catches 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 Correos del Ecuador has assigned it to a real canton or zone. Confirming that requires Ecuador’s own postal code lookup.

Scope: this page and tool cover código postal format validation only — not address lookup, province matching, or confirming a code is currently in use.
