What Is the Format of the Canadian Postal Code?

Canada’s postal codes share close similarities with the postcodes of the United Kingdom, Ireland, and the Netherlands, as all of these have alphanumeric characters.

However, the Canadian postal codes are in the format of K1K 1K1, where ‘K’ is an alphabet and ‘1’ is a numeral, with a space separating the third and the fourth character.

Canadian postal code contains two very important components which denote—Forward Sortation Area (FSA) and Local Delivery Unit (LDU).

  1. Forward Sortation Area (FSA): The first three characters denote the territory in Canada. The second character is a numerical digit that denotes whether it’s an urban region or rural. All the numerals represent urban regions except zero which is for rural regions. The first three characters all together help represent a specific geographical location.
  2. Local Delivery Unit (LDU): The last three characters of the postal code denote a single address or a range of different addresses, which correspond to a small town, a significant portion of a medium-sized town, an entire block in bigger cities, a big building, university, etc., that receive a lot of mail regularly.

It’s important to notice that Canadian postal codes use 20 uppercase letters of the English alphabet except D, F, I, O, Q, or U. Letters like W and Z are also not used.
