What Is an Importer BN15? Canadian Import Identifier Explained

Importer BN15 The 15-character Canadian identifier combining a BN9 with an RM import program account for a commercial importer.

The Importer BN15 is the formatted code used by Canadian authorities, customs brokers and carriers to identify a commercial importing entity on regulatory documents and electronic manifests. It is built from a business's nine-digit Business Number (BN9) issued by the Canada Revenue Agency (CRA) followed by the two-letter program identifier "RM" and a four-digit account reference (for example: 123456789RM0001). That 9 + 2 + 4 structure produces the full 15-character string that appears on customs entries, invoices and electronic transmissions to the Canada Border Services Agency (CBSA).

How The Identifier Is Structured

Structure matters because federal systems and third‑party software validate the BN15 format.

• BN9: A nine-digit number the CRA issues to a business as its core Business Number.
• Program Identifier: "RM" specifically denotes an import/export program account used for customs activities.
• Account Suffix: Four digits (0001, 0002, etc.) allow a business to hold multiple RM accounts when needed.

Why It Matters For Commercial Importers

Customs clearance, duty and tax assessment, and record-keeping all hinge on correct importer identification. The BN15 links a shipment to the legal entity that is responsible for paying duties, claiming refunds or credits, and maintaining import records for audit. Incorrect or missing BN15 data delays release, triggers assessments or penalties, and can complicate entries under bonded or clearance procedures.

Where You Use The BN15

The BN15 appears on every step of the import workflow for commercial goods.

• Customs Entry Forms: The B3 Canada Customs Coding Form references the importer account to calculate duties and taxes.
• Electronic Manifests: Carriers and freight forwarders must supply the importer identifier in eManifest and release messages to CBSA.
• Brokerage and Invoices: Customs brokers, freight forwarders and commercial invoices list the BN15 so receivers and brokers can match shipments to accounts.

Who Needs One And Who Uses It

Any company engaged in importing commercial goods into Canada must use an RM program account attached to its BN9 when clearing customs. Importers that import periodically may use a customs broker who will work under the importers BN15. Carriers, freight forwarders and bonded warehouse operators use the number to route, report and release shipments on behalf of the importer.

How To Obtain And Maintain An RM Account

Registering for a BN9 and adding an RM account is handled through the CRA:

• Register BN9: Apply online via CRAs business registration or by phone; registration is free.
• Add RM Program Account: Request an RM account (import/export) and a four-digit suffix; this can be done during registration or added later through CRA services.
• Maintain Records: Keep account information current with CRA (address or ownership changes) to avoid mismatches during clearance.

Common Operational Issues And Fixes

Practical problems crop up when the BN15 is misformatted or missing.

• Formatting Errors: Remove spaces or dashes; use the full 15-character string exactly (example: 123456789RM0001).
• Wrong Account Suffix: Verify the four-digit suffix with CRA; brokers cannot guess the correct suffix when multiple RM accounts exist.
• Mismatch In Systems: Ensure your ERP/WMS and broker systems hold the identical BN15 string to prevent electronic rejection by CBSA.

Practical Example

A Toronto retailer imports a pallet of electronics. Their CRA-issued Business Number is 987654321; they use RM account 0001 for general imports. The correct importer identifier on the commercial invoice and the B3 form is 987654321RM0001. The customs broker uses that BN15 when filing the electronic B3 and the carrier includes it in the eManifest. Duties and GST/HST are assessed to the account tied to that BN15, and any post-entry adjustments reference the same identifier.

Tips For Warehouse And Logistics Teams

• Labeling: Confirm the BN15 on purchase orders and packing lists before goods depart origin; include it on ASN/EDI transmissions.
• Broker Coordination: Share a verified BN15 with your customs broker and carrier early in the shipment booking process.
• Audit Trail: Keep a digital copy of the BN15 and registration documents in your WMS or ERP for quick access during audits.

In short, the Importer BN15 is the combined BN9 and RM program account string that uniquely identifies a Canadian commercial importer for customs, accounting and compliance purposes. Using the correct 15-character format on electronic filings and paperwork reduces release delays, prevents assessment errors and keeps cross-border operations running smoothly.
