With SIN Online, if everything is in order, you will receive a letter by mail with your SIN within 15 business days from the date your application was received. If it has been more than 15 days since you applied online, and you have not received a letter, please contact the SIN Program.

Apply

There is no fee to apply for a SIN.

Submit a SIN application to:

• request a SIN for the first time
• obtain a confirmation of your SIN
• correct an error on a SIN record
• update a legal change of name
• update the citizenship status on your SIN record
• update your immigration document’s expiry date on your SIN record
• remove your disc number from your SIN record

Include all mandatory documents with your application.

Service Canada will only mail your Confirmation of SIN letter to an address other than your own if you apply by mail.

To protect your personal information, never leave your computer or device unattended while filling out a SIN application online. Always close your browser if you step away from your computer or device.

Minors applying for themselves

Children who are 12 years of age or older may apply for their own SIN.

If you are under the age of majority in your province or territory and applying for a SIN, you must provide all required documents. If you cannot provide all required documents, a representative must apply on your behalf.

Indian status

If you are an individual registered under the Indian Act and you want to register your status in your SIN record, provide a Certificate of Indian Status issued by the Government of Canada along with your required documents (see “Apply for a SIN” section below to obtain the list of required documents).
