If you’re planning to import goods into Canada, you’ll need more than just a shipping schedule and a commercial invoice. One of the first and most crucial steps is securing an importer number, a unique identifier that allows the Canada Border Services Agency (CBSA) to track your shipments and transactions.

So, what exactly is this number, and how is it connected to your Business Number (BN)? Here’s a simplified breakdown to help you understand.

What is an Importer Number?

The CBSA uses an importer number to recognize you as the party responsible for shipments entering Canada. Without it, your goods won’t be cleared at the border.

In most cases, your importer number is based on your Business Number (BN) from the Canada Revenue Agency (CRA), formatted like this:

123456789RM0001

  • The first 9 digits are your BN
  • “RM” indicates an import/export program
  • “0001” is the specific account identifier

If you’re importing under a business entity, you must obtain this number before your goods arrive.

Do You Need a Business Number (BN)?

Yes, if you’re importing commercially.

The Business Number (BN) is a universal number used by the federal government to manage your tax accounts (like GST/HST, payroll, and import/export). You’ll need to register for an import/export account linked to your BN to legally bring goods into the country.

Individuals vs. Businesses

  • Businesses must register for a BN with an RM import/export account
  • Individuals importing goods for personal use don’t need a BN but may still need to declare goods and pay duties

If you’re new to importing and only bringing in small quantities for evaluation or resale testing, you may begin as an individual. However, as your volume or frequency increases, registering as a business becomes essential.

How to Get an Import/Export Account

Registering for an import/export account in Canada is a straightforward process. You can do it in one of the following ways:

  • Online through the CRA Business Registration Online
  • By phone at 1-800-959-5525
  • Through a licensed customs broker for importers who can help manage the entire process

Once you have this account, you can start importing under your business name with full legal and tax compliance.

Can Non-Residents Get an Importer Number?

Yes. Foreign businesses can become Non-Resident Importers (NRIs), which allows them to ship goods into Canada without a physical presence in the country. This is ideal for eCommerce sellers or U.S. businesses wanting access to the Canadian market.

Why This Matters

Without a valid importer number:

  • Your goods may be held at the border
  • You could face delays, penalties, or storage fees
  • Customs declarations will be incomplete
  • You may be blocked from claiming GST/HST input credits

For first-time importers, following a step-by-step guide to clearing customs is a smart place to start.

Tips to Keep in Mind

  • Apply early – Don’t wait until your shipment is en route
  • Double-check your BN – Use the correct 15-digit format
  • Use a customs broker – They can set up your account and file entries on your behalf
  • Stay compliant – Renew and update your information if your business changes
