About postal codes
Postal and ZIP codes are how mail is sorted and delivered, and every country uses a different format. This directory publishes country-level formats, validation patterns, and examples so you can write addresses correctly.
Frequently asked questions
What is the difference between a postal code and a ZIP code?
ZIP code is the specific name for the postal code system used in the United States. Other countries call them postcodes, PIN codes, or simply postal codes. They all serve the same purpose: routing mail to the right delivery area.
Why do postal code formats differ so much between countries?
Each postal service designs its own code to match its geography and mail volume. Canada uses alternating letters and digits (K1A 0B1), the UK uses outward and inward halves (SW1A 1AA), and the US uses five or nine digits (90210).
What is an alphanumeric postal code?
An alphanumeric postal code mixes letters and digits, which allows more unique combinations in a shorter string. The UK and Canada use this style, while countries like the US and Japan use numeric-only codes.
How accurate is a country-level postal format?
This directory publishes the official national format and validation pattern, not individual addresses or delivery records. It is accurate for validating that a code looks right for its country, but not for confirming a specific address exists.
