Business number or program registration
Your nine-digit business number identifies the business. Program accounts add a program identifier and reference number.
What this usually means
Your nine-digit business number identifies the business. Program accounts add a program identifier and reference number.
What to do next
Check the legal name, address, program type and effective date. A business number by itself does not mean you are registered for every tax program.
Check the actual letter
Confirm the tax year or reporting period, account type, reference number, requested records and exact response/payment date. There is no single deadline that applies to all CRA letters.
Keep a response trail
Save the notice, relevant return or statement, supporting invoices/receipts and a copy or confirmation of anything submitted. Avoid sending more sensitive information than requested.
Verify who contacted you
Open Canada.ca yourself and sign in through the official CRA page to check secure correspondence. For a call or unexpected request, use an independently found official contact route; matching a logo or phone number is not proof.
