Canada Post Postal Code Format and Lookup Guide

This page is built for users searching phrases like canada post postal code, zip code lookup, and check postal code.

Use the references below to understand format rules, validate code structure, and jump into postal code lookup pages for real location results.

Canada Post Postal Code Format

The standard Canadian format is A9A 9A9. The first three characters are the Forward Sortation Area (FSA), and the last three characters narrow delivery routes and local addresses. In most cases, the first letter maps to a province or territory group. Ontario and Quebec use multiple first-letter ranges because of population and address volume. The second character helps indicate rural versus urban routing, where 0 represents rural routing.

  • Valid structure: letter-digit-letter space digit-letter-digit
  • Case-insensitive for search, typically stored uppercase
  • Example format: M5V 2T6
  • Commonly excluded letters in Canadian codes include D, F, I, O, Q, and U
