A Canadian Registration Number (CRN) for a boiler or pressure vessel is defined by CSA B51 Clause 4.3 as:

  • consisting of a letter, four digits, and a decimal point followed by up to ten digits and/or two letters

  • the first letter and four digits are part of a sequential numbering system used by the issuing province or territory

  • the first digit or letter to the right of the decimal point indicates the province that issued the particular number

  • the following identifications are used in accordance with the code:
    1 - British Columbia
    2 - Alberta
    3 - Saskatchewan
    4 - Manitoba
    5 - Ontario
    6 - Quebec
    7 - New Brunswick
    8 - Nova Scotia
    0 (zero) - Newfoundland
    T - Northwest Territories
    Y - Yukon Territory
    N - Nunavut

  • the letter C may follow the designation of first registration if a design is registered in all jurisdictions. No jurisdiction issues the letter C; it is a convenience for stamping once the manufacturer has received all the registrations.

  • to be eligible for use in Alberta, the CRN must have the digit 2 somewhere after the decimal point.
