Does the SIN have a check digit? Alphax τεχ 11:34, 28 Apr 2005 (UTC)
The main difference between the SIN and the US Social Security Number being used as an ID number is that in Canada a SIN can only be required when it is needed to comply with the law and when no other means of identification will work. If the law does not require that a SIN be given, then service cannot be denied on the basis of refusing to provide the SIN. In the US, if a person refuses to provide a SSN to someone, they can be denied service because of it.
For example: In Canada, a gas station cannot require that all customers provide their SIN in order to purchase gasoline, as the law does not specify this. The gas station would be free to request it, but if the customer said no, the gas station would not be able to refuse to sell gasoline to that person on the basis that they would not provide their SIN. In the US a gas station could require all customers to provide an SSN in order to purchase gasoline, and if the customer refused, the gas station would not have to sell gasoline to that person.
So, while the SIN is used as an identification number in Canada, the areas where it can be used are much smaller. Steggall 17:51, 13 Nov 2005 (UTC)
[edit] Fair use rationale for Image:SIN.png
Image:SIN.png is being used on this article. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.
Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Wikipedia:Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.
If there is other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page. Note that any fair use images lacking such an explanation can be deleted one week after being tagged, as described on criteria for speedy deletion.
