Demystifying the Canadian Registration Number (CRN)

The Canadian Registration Number (CRN) plays a crucial role in ensuring the safety and compliance of pressure equipment like boilers, pressure vessels, fittings, and piping systems across Canada. Here’s a breakdown of its key aspects:

What it is:

  • A unique number assigned to a pressure equipment design by a specific province or territory in Canada.
  • Indicates that the design meets the safety requirements of the applicable codes and regulations in that jurisdiction.
  • Acts as a mark of approval for the equipment’s safe use.


  • Consists of a letter, four digits, a decimal point, and up to ten additional digits and three letters.
  • The first letter and four digits are unique to the issuing province or territory and follow a sequential numbering system.
  • The first digit after the decimal point specifies the issuing province/territory: 1 – BC, 2 – AB, 3 – SK, etc.
  • Additional letters like “C” or “CL” may be used to indicate registration in all jurisdictions or all mandatory ones, respectively.


  • Enhances safety by ensuring equipment adheres to established safety standards.
  • Facilitates trade and compliance by simplifying interprovincial movement of pressure equipment.
  • Provides clear identification of approved equipment for inspectors and users.

Where to find it:

  • Stamped on the nameplate of the pressure equipment.
  • Included in the equipment’s documentation and data report.

Benefits for users:

  • Confidence in the safety and reliability of the equipment.
  • Streamlined compliance with local regulations.
  • Reduced risk of accidents and potential liabilities.

Overall, the Canadian Registration Number is a valuable tool that promotes safety, standardization, and efficient trade within the pressure equipment industry across Canada.

I hope this explanation clarifies your understanding of the CRN and its significance. Feel free to ask any further questions you may have!
