Chile código postal validator
How the código postal format works
- Format
- 7 digits
- Example
- 8320000
Things to watch for
- Format-only check — does not confirm the código postal actually exists
- Always exactly 7 digits with no separators; the first three encode the region and comuna, the last four a city block
- Chilean addresses are usually delivered fine without it — Correos de Chile mainly requires the code for bulk mail, so day-to-day use is inconsistent
^[0-9]{7}$A Chilean código postal is the 7-digit code Correos de Chile assigns down to city-block level — for example 8320000 for Santiago Centro. It’s longer than the 4- or 5-digit codes common elsewhere in Latin America because the final four digits pinpoint a specific block rather than a broad delivery zone, but that precision comes with a catch: Correos de Chile treats it as mainly a bulk-mail requirement, so plenty of everyday Chilean addresses go without one and still get delivered on the comuna name alone. Anyone validating a Chilean shipping address, checkout form, or spreadsheet of customer records where a código postal is supplied needs it to be the right length and shape before it’s trusted.
Because the code is a bare 7-digit run with no separator, a code with a missing digit or one padded from a shorter foreign format 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 7 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 7 digits long is the most a client-side tool can do — not that Correos de Chile has assigned it to a real block. Confirming that requires Correos de Chile’s own postal code lookup.
Scope: this page and tool cover código postal format validation only — not address lookup, comuna matching, or confirming a code is currently in use.
código postal FAQ
How many digits does a Chilean postal code have?
Always 7 — noticeably longer than most Latin American postal codes. For example, 8320000 covers central Santiago (Santiago Centro).
Do I actually need a postal code for everyday mail in Chile?
Not always. Correos de Chile mainly requires the 7-digit código postal for bulk mail and business shipments; a lot of everyday residential mail is delivered fine on the commune and street name alone, so its use is less universal than in countries where the postal code is mandatory.
What do the 7 digits of a Chilean código postal encode?
The first three digits identify the region and comuna (municipality), and the remaining four narrow it to a specific city block.
