What Is An Alberta Identification "A" Number?

• An Alberta identification number (or "A-number") is a unique number that identifies each boiler or pressure vessel manufactured for use in Alberta. The number is assigned by a Safety Codes Officer upon completion of the shop inspection (if manufactured in Alberta) or upon completion of initial inspection (if imported into Alberta).

• An A-number begins with the letter "A" (in a circle) followed by up to seven numbers. It is usually stamped on the pressure equipment item, on or near the nameplate or code stamping.

• Pressure vessels and boilers manufactured in Alberta for export are not usually assigned an A-number.
