Canadian Province and Territory Abbreviations

Official Two-Letter Codes (Canada Post Standard)

Usage Notes

• Postal addresses: Use these codes (e.g., "Toronto, ON M5G 2C4")
• Data/IT: Standard in Canadian databases, APIs, GIS
• Vehicle plates: Most provinces use same codes (except NL=NF older, NT=NT, NU=NU, YT=YT)
• ISO 3166-2:CA: Identical (CA-AB, CA-BC, etc.)

Common Confusions

• NB = New Brunswick (not Newfoundland)
• NL = Newfoundland and Labrador (changed from NF in 2002)
• PE = Prince Edward Island (not "PEI" — that's 3 letters)
• QC = Quebec (not PQ — old code, still seen)
