Social Insurance Number (SIN)

The SIN is a nine-digit number used in the administration of various Canadian government programs; it is required to work in Canada and to receive government benefits. Available to Canadian citizens, newcomers to Canada, or temporary residents aged 12 and older. Application forms for a new or replacement SIN number can be obtained from local Service Canada Centres. You must apply in-person at a Service Canada Centre unless you live 100 km or more from the nearest Service Canada point of service, in an inaccessible area, or where outreach is very infrequent, or, if other extenuating limitations prevent you from visiting a Service Canada Centre; see website for details. Primary identification that proves the person's identity and status in Canada is required.
