The manufacturer of the pressure-retaining item must apply for a CRN number from the Canadian Authorities.

The manufacturer must apply to the Canadian Authorities, along with drawings and specifications of the pressure-retaining item. The Canadian Authorities will review the application and, if everything is in order, will assign a CRN number to the item.

Take note that the CRN review process can take up to six weeks.

The Canada Registration Number (CRN) is a unique identifier assigned to pressure-retaining items, such as boilers and pressure vessels registered with the Canadian Authorities. The CRN is issued by province and consists of nine characters: one letter followed by eight digits.

For example, the CRN for a boiler might be “B12345678”.  The CRN is stamped on the pressure-retaining item by the manufacturer and must be recertified every five years.

The CRN tracks boilers and pressure vessels throughout their life cycle, from manufacture to installation to operation. When a boiler or pressure vessel changes hands, the new owner must notify the Canadian Authorities, and the CRN is updated in the registration database.

This helps to ensure that boilers and pressure vessels are properly maintained and operated and that any safety issues are quickly addressed.
