The CRA business number (BN) is your 9-digit, federally assigned number for federal tax purposes. The Ontario Business Identification Number (BIN) is a provincial number issued by the Ontario Business Registry.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">On the Ownr dashboard, both appear in the Organization Information panel. Look for the field labeled Business Number for your CRA business number. The other field, Business Information Number, is your provincial BIN.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As mentioned in Method 1, Ownr does not display CRA business numbers for Ontario sole proprietorships created after August 5, 2025. Register directly with CRA through BRO. It may take up to 4 days for CRA to assign your Business Number.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Business Number vs Business Registration Number: What&#8217;s the Difference?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Canadian business owners often confuse four separate identifiers. Here&#8217;s how they differ.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The CRA business number (BN) is a 9-digit, government-issued number from the Canada Revenue Agency. You use it for GST\/HST, payroll, and corporation income tax.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The business registration number (also called a BIN in Ontario) is a provincial identifier issued by a provincial business registry, such as the Ontario Business Registry. It identifies your business within the province.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The <\/span><a href="\&quot;https:\/\/www.ownr.co\/blog\/business-number-vs-corporation-number\/\&quot;"><span style=\"font-weight: 400;\">incorporation number<\/span><\/a><span style=\"font-weight: 400;\"> (also called corporation number) is assigned by Corporations Canada or a provincial registry when you incorporate. People often confuse their business number with their corporation number. Your BN is your federal tax ID. Your corporation number confirms your business exists as a corporation.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The GST\/HST account number is not a separate number. It is your BN plus &#8220;RT 0001.&#8221;<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">What to Do If You Can&#8217;t Find Your Business Number<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">If more than 4 business days have passed since registration and you still don&#8217;t see a BN, CRA may not have assigned a new BN. This often happens when you previously registered a sole proprietorship under the same legal entity. Your existing BN carries over to the new registration.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If your original documents and online methods haven&#8217;t helped, reach out to the registry that handled your registration:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Ontario Sole Proprietorships &amp; Corporations:<\/b> <a href="\&quot;https:\/\/www.ontario.ca\/page\/ontario-business-registry\&quot;" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Ontario Business Registry<\/span><\/a><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Alberta Sole Proprietorships &amp; Corporations:<\/b> <a href="\&quot;http:\/\/www.servicealberta.gov.ab.ca\/find-a-registry-agent.cfm\&quot;" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Alberta Registry Agent<\/span><\/a><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>BC Sole Proprietorships &amp; Corporations: <\/b><a href="\&quot;https:\/\/www2.gov.bc.ca\/gov\/content\/governments\/organizational-structure\/ministries-organizations\/ministries\/citizens-services\/bc-registries-online-services\&quot;" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">BC Registries and Online Services<\/span><\/a><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Federal Corporations:<\/b> <a href="\&quot;https:\/\/ised-isde.canada.ca\/cc\/lgcy\/fdrlCrpSrch.html\&quot;" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Corporations Canada<\/span><\/a><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">If none of the above resolves the issue, call the CRA telephone service (1-800-959-5525), Monday to Friday, 8 am to 8 pm ET.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Non-resident business owners should use the CRA online form to request a callback from a non-resident tax specialist.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Set Up Your Business with Ownr.co<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">When you incorporate or register a sole proprietorship through Ownr, Ownr handles your CRA registration.
