Service Canada SIN office no longer issues SIN cards since 2014. Since then, a paper format was issued to replace the card version. This paper format is called the Confirmation of SIN paper and does not have any security features on the print. This letter was only printed from Service Canada office to confirm that your SIN belongs to the named person on the letter. Do keep in mind that what’s important is the numbers, not the card or the paper. Therefore, do not share your SIN lightly to anyone or any institution that legally requires you to use it.

The Confirmation of SIN letter is not intended to be used as an identification or an official letter from Service Canada.

If you have lost your SIN card, you will no longer be issued a new card. You will only receive the Confirmation of SIN letter. There are a few options to obtain this letter:

1. Visit your local Service Canada centre in person with the appropriate documents.
2. Submit your Confirmation of SIN letter requests through Service Canada’s online SIN request service. 
3. By mail. Complete the appropriate form(s) – NAS2120 – with supporting document attached and mail to SIN head office in Bathurst, NB.
