Understanding CRN

What Is a Canadian Registration Number?

A CRN is a registration number issued by a Canadian province or territory after its safety authority reviews and accepts the design of a boiler, pressure vessel, or pressure-retaining fitting. Pressure equipment needs a CRN in each province or territory where it will be installed and operated.

Design Reviewed

The design, materials, and pressure and temperature ratings are reviewed against the CSA B51 Boiler, Pressure Vessel, and Pressure Piping Code.

Registered Province by Province

Each province and territory has its own safety authority, so a CRN applies only in the jurisdictions where the design has been registered or accepted.

Required Before Installation

Inspectors and operators check for a valid CRN before pressure equipment goes into service. Having it on file keeps project approvals moving.

Reading the Number

How to Read a CRN

Everything before the decimal identifies the registered design. The digits after the decimal show where it's registered: the first digit is the province that first registered it, and each digit after that is a province that has also accepted it.
