Canadian provincial and territorial postal abbreviations are used by Canada Post, currently in code system of two capital letters, to represent the 13 provinces and territories on addressed mail. These abbreviations allow automated sorting. The current codes replaced the inconsistent designation system used by Canadians until the 1990s.

[edit] Current abbreviations

The sources of the current abbreviations vary. Some are from the initials of two of the words in the name of a province or territory, while others are from the first and final letter or from the first and some other letter in the name. All of these names are based on the English form of the name, though they also correspond to their French equivalents in various ways (for example, NT could be read for the first and last letters of Nord-Ouest, instead of Northwest Territories). For Quebec and New Brunswick, the two provinces with large numbers of French-speakers, the initials in both languages are identical. French equivalents of each abbreviation once existed: see Former abbreviations. Manitoba's abbreviation is due to U.S. states already having abbreviations in all of the letters of the province's name besides "B".

These abbreviations are fully compatible with the equivalent two-letter codes used for states and territorial areas of the United States, because no abbreviations overlap. The policy of not overlapping adjacent-country abbreviations effectively precludes use of NV (Nevada) in Nunavut and T-N as « Terre-Neuve » (Newfoundland). This policy later became a formal agreement between Canada Post and the USPS.^{[citation needed]}

There are no Canadian provinces with names potentially overlapping any other adjacent-country territorial abbreviations, such as SPM and GL, so the issue is presently confined to U.S. addresses.

Abbreviation	English name	French name	Source
AB	Alberta	Alberta	First letter of first two syllables
BC	British Columbia	Colombie-Britannique	Initials
MB	Manitoba	Manitoba	First letter of first and last syllables
NB	New Brunswick	Nouveau-Brunswick	Initials
NL	Newfoundland and Labrador	Terre-Neuve-et-Labrador	Initials
NS	Nova Scotia	Nouvelle-Écosse	Initials
NT	Northwest Territories	Territoires du Nord-Ouest	Initials
NU	Nunavut	Nunavut	First two letters
ON	Ontario	Ontario	First two letters
PE	Prince Edward Island	Île-du-Prince-Édouard	Initials of first two words
QC	Quebec	Québec	First and last letters
SK	Saskatchewan	Saskatchewan	First letter of first two syllables
YT[A]	Yukon	Yukon	Initials of "Yukon Territory"

(Note: The Canadian policy of adopting non-overlapping abbreviations to adjacent countries was opposite to the policy adopted by Mexico, where the most convenient two-letter^{[citation needed]} combinations were chosen, regardless of whether that combination was already in use in the United States or Canada, e.g., CO Coahuila, MI Michoacán, MO Morelos, NL Nuevo León, BC Baja California.)

Newfoundland and Labrador's abbreviation became effective 21 October 2002 to reflect the provincial name change from "Newfoundland" to "Newfoundland and Labrador" on 6 December 2001.

In 1991, the code for Quebec was changed from PQ to QC.

Nunavut's code became effective 13 December 2000; before this date, but after Nunavut's creation on 1 April 1999, the abbreviation "NT" was used for Nunavut as well as the Northwest Territories. Canadian postal codes begin with "X" for both NT and NU, the only two territorial or provincial jurisdictions to share the same initial postal code letter. However, the new code NU was chosen to stem possible confusion and to reflect the new territory's creation.

These abbreviations are not the source of letters in Canadian postal codes, which are assigned by Canada Post on a different basis than these abbreviations. While postal codes are also used for sorting, they allow extensive regional sorting. In addition, several provinces have postal codes that begin with different letters.

A sample of a proper address:^[1][2]

PAT ANYONE
1643 DUNDAS ST W APT 27
TORONTO ON  M6K 1V2

Note that the street type, unit type, and city quadrant, if applicable, are abbreviated, without periods (though using periods, or even spelling out every word in its entirety, is unlikely to affect delivery in any way). Note also the lack of a comma between municipality and province/territory, the double space between the latter and the postal code, and the single space between segments of postal code, all on one line. Addresses should be done in all-upper-case without punctuation, and the unit number may precede street number, with a hyphen, e.g., "27-1643 DUNDAS ST W" using the above example.^[2][3][4]

[edit] Former abbreviations

Though deprecated as postal abbreviations, the following are still often used as abbreviations in other contexts. Some of the abandoned French versions included a hyphen. The eventual goal became to standardize all abbreviations into two-character units. In French, with the hyphen, it became a three-character abbreviation, yet, without it, conflict arose with US state abbreviations, e.g., a hyphenless T-N became TN (a duplicate of Tennessee); N-E became NE (a duplicate of Nebraska). Over time, the English forms became standard. Nunavut (created in 1999) does not have a former abbreviation because it did not exist when these codes were phased out.

• Alberta — Alta. ^[C]
• British Columbia — B.C. and C.-B. (the latter is the French version, for Colombie-Britannique)
• Labrador — LB This appeared in Canada Post publications (e.g., The Canadian Postal Code Directory) for the mainland section of the province of Newfoundland and Labrador.
• Manitoba — Man.
• New Brunswick — N.B.
• Newfoundland — Nfld. and later NF (the two-letter abbreviation used before the province's name changed to Newfoundland and Labrador) and T.-N. (French version, for Terre-Neuve) ^[D]
• Northwest Territories — N.W.T. and T.N.O. (French version, for Territoires du Nord-Ouest)
• Nova Scotia — N.S. and N.-É. (French version, for Nouvelle-Écosse)
• Ontario — Ont.
• Prince Edward Island — P.E.I. and Î.P.É. (French version, for île du Prince-Édouard);
• Quebec — Que. and P.Q. (French version, for Province de Québec); later, PQ evolved from P.Q. as the first two-letter non-punctuated abbreviation. Later still, QU evolved as the second two-letter non-punctuated abbreviation, making Quebec's abbreviation consistent with other provinces insofar as using letters solely from the name of the province, but not the word "province", as PQ did. There may also have been political considerations, as "PQ" was and is common shorthand for the Parti Québécois. New York State and New York City have decided arbitrarily to use "QB" to identify Québec Vehicle Licence Plates.
• Saskatchewan — Sask.
• Yukon — Yuk.

[edit] Notes

A. ^ Commonly though unofficially YK (also used in the second-level country code domain name space yk.ca). ISO-3166-2 lists YT as official [1].

C. ^ Also commonly, but unofficially Alb. in French.

D. ^ LB was commonly but unofficially used for Labrador.
