Paraguay código postal validator
How the código postal format works
- Format
- 6 digits
- Example
- 001001
Things to watch for
- Format-only check — does not confirm the código postal actually exists
- Always exactly 6 digits with no separators, including leading zeros
- DINACOPA replaced Paraguay's old 4-digit postcode with this 6-digit system in June 2018 — the first two digits are the department, the next two the district, and the last two the neighborhood
^[0-9]{6}$A Paraguayan código postal is the 6-digit code DINACOPA introduced nationwide in June 2018, replacing an older 4-digit system — for example 001001 for downtown Asunción. Because the change is only a few years old, older records, printed materials, or forms copied from before 2018 can still carry the legacy 4-digit code, which no longer matches the current national standard. Anyone validating a Paraguayan 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 4-digit code from before the 2018 change is immediately the wrong length under the current system — exactly the kind of mismatch a shape check is built to catch.
How this validator works
This tool checks that the input is exactly 6 digits, leading zeros included, 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 matching the 6-digit shape is the most a client-side tool can confirm — not that DINACOPA has assigned it to a real neighborhood. Confirming that requires Paraguay’s own postal code lookup.
Scope: this page and tool cover código postal format validation only — not address lookup, department matching, or confirming a code is currently in use.
código postal FAQ
Didn't Paraguay used to have a 4-digit postal code?
Yes — DINACOPA (Paraguay's national postal authority) replaced the older 4-digit system with the current 6-digit format in June 2018, so any code shorter than 6 digits reflects the pre-2018 standard rather than the one in use today.
What do the digits of a Paraguayan postal code encode?
The first two digits are the department, the third and fourth the district, and the last two the neighborhood or town — 001001, for example, covers downtown Asunción.
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 DINACOPA's actual assignment list. Confirming a code is real requires Paraguay's own postal code lookup.
