Random Canadian postal codes.

How the generator builds a postal code

A Canadian postal code is six characters: letter, digit, letter, a space, digit, letter, digit (A1A 1A1). The first three characters are the forward sortation area (FSA) and the last three the local delivery unit. This tool fills each position at random from what Canada Post allows, and nothing more.

• Letters: 20 are used (A B C E G H J K L M N P R S T V W X Y Z). D, F, I, O, Q and U are never used; W and Z never start a code.
• First letter: chosen from the province table: A Newfoundland and Labrador, B Nova Scotia, C Prince Edward Island, E New Brunswick, G/H/J Quebec, K/L/M/N/P Ontario, R Manitoba, S Saskatchewan, T Alberta, V British Columbia, X Northwest Territories/Nunavut, Y Yukon.
• Second character: 0 is rural, 1 to 9 is urban. Urban only unless you tick the rural option.
• Remaining positions: a digit 0 to 9 or one of the 20 letters as the pattern requires, drawn with the browser’s cryptographic random source, with duplicates removed.

Worked example

Choose Alberta and ask for one code. Alberta maps to the first letter T. The generator picks an urban second digit, say 5, then letters and digits to match the pattern: for example T5K 2R8. Every position is legal (T is Alberta, 5 is urban, K and R are in the 20-letter set), so it passes a format check. Whether T5K 2R8 is an actual delivery area is a separate question this tool cannot answer.

Not for real addresses

Random codes can collide with real ones and say nothing about a street or building. Use them for form validation, database seeding, screenshots and QA only. To check one against the province on an address, use the Postal Code to Province Checker; to confirm a real address, use Canada Post’s own lookup.

• Wikipedia, Postal codes in Canada, quoting Canada Post: “Postal codes use twenty uppercase letters of the English alphabet; they do not include the letters D, F, I, O, Q, or U,” and “The first position also does not make use of the letters W or Z.”

Postal code generator FAQ

Are the generated postal codes real?

They follow the real format (A1A 1A1, first letter matching the province, never D F I O Q U), but they are random. A code may by chance match a real delivery area or may not exist at all. Never use them to mail anything or to claim an address exists.

What makes a Canadian postal code format-valid?

Six characters in the pattern letter-digit-letter, space, digit-letter-digit. Canada Post uses 20 letters (A B C E G H J K L M N P R S T V W X Y Z) and never D, F, I, O, Q or U. W and Z are not used as the first letter.

How does the province setting work?

The first letter of a postal code identifies the province or territory: for example V is British Columbia, T is Alberta, and G, H and J are Quebec. The generator picks the first letter from that Canada Post table. X is shared by the Northwest Territories and Nunavut, so choosing either gives an X code.

What does the rural option do?

The second character is 0 for a rural code and 1 to 9 for an urban one, per Canada Post. Rural codes are off by default; turn the option on to include second-character 0.

Is it random enough for testing?

Yes for form and database testing. It uses the browser's cryptographic random source and removes duplicates within a batch. It is not a model of real code density, so it will not reproduce the real distribution of postal codes.

Is anything I generate sent anywhere?

No. Generation runs entirely in your browser; nothing is transmitted, stored or logged.
