Guatemala código postal validator
How the código postal format works
- Format
- 5 digits
- Example
- 01001
Things to watch for
- Format-only check — does not confirm the código postal actually exists
- Always exactly 5 digits with no separators, including the leading zero for the capital's department code
- The first two digits identify the department, the third a route, and the last two the delivery office — 01001 covers Zone 1 in Guatemala City
^[0-9]{5}$A Guatemalan código postal is the 5-digit code used to route mail — for example 01001 for Zone 1 in Guatemala City. Its three-part structure (department, then route, then office) is compact but specific: department numbering starts at 01, so the capital’s own department keeps a leading zero as a genuine part of every one of its postal codes rather than as an optional formatting flourish. Anyone validating a Guatemalan shipping address, checkout form, or spreadsheet of customer records needs the leading zero preserved and the full 5 digits present before it’s trusted.
A common data-entry slip is dropping Guatemala department’s leading zero when a form or spreadsheet treats the postal code as a number rather than text, silently shortening 01001 to 1001 — a length check catches this immediately.
How this validator works
This tool checks that the input is exactly 5 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 confirming it’s 5 digits long is the most a client-side tool can do — not that it’s been assigned to a real office. Confirming that requires Guatemala’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
What do the 5 digits of a Guatemalan postal code encode?
The first two digits identify the department, the third digit marks a route, and the last two identify the delivery office — so 01001 covers Zone 1, the historic center of Guatemala City, in Guatemala department.
Why does the example code start with a zero?
Guatemala department (home to Guatemala City) is department 01 in the numbering scheme, so its postal codes keep that leading zero rather than dropping it — a code missing the leading zero would be the wrong length and invalid.
Does a correctly formatted código postal mean it actually exists?
No. This tool only confirms the string is 5 digits — it doesn't check it against Guatemala's actual postal assignment list. Confirming a code is real requires Guatemala's own postal code lookup.
