魁省这里发的工卡都是2开头, 来的越早开头3位数越小, 我看到最小的是220开头的. 我03年登陆领到的卡是293开头, 去年给儿子申请的是296开头的了. 不知最近申请的是29几开头的了? 很快就要300开头了(目前好象全国都没300开头的SIN卡, 应该是为魁省预留的)
中国人喜欢推理,觉得有道里就正确了.
很简单,查一下资料就有答案了.

A sample SIN card.
A
Social Insurance Number (SIN) is a number issued in
Canada to administer various government programs. The SIN was created in
1964 to serve as a client account number in the administration of the
Canada Pension Plan and Canada's varied employment insurance programs. In
1967, Revenue Canada (now the
Canada Revenue Agency) started using the SIN for tax reporting purposes. SINs are issued by
Human Resources and Skills Development Canada (previously
Human Resources Development Canada).
The SIN is formatted as three groups of three digits (e.g., 123-456-789).
Through
functionality creep, the SIN has become a
de facto national identification number, much in the same way as the
Social Security Number in the
United States. However, unlike in the US, in Canada there are specific legislated purposes for which a SIN can be requested. Unless an organization can demonstrate that the reason they are asking for a person's SIN is specifically allowed by law, or that no alternative identifiers would suffice to complete the transaction, they cannot deny or refuse a product or service on the grounds of a refusal to provide a SIN. Examples of organizations that legitimately require an SIN include employers, banks and investment companies, and federal government agencies. Giving an SIN when applying for consumer credit, such as buying a car or electronics, or allowing it to be used as a general purpose identification number, such as by your cable company, is likely a bad idea.
Social Insurance Numbers that begin with the number "9" are issued to
temporary residents who are not Canadian citizens (e.g., foreign students, individuals on work
visas) or
permanent residents. These individuals must have an employment authorization in order to work in Canada. SINs beginning with a "9" are different from SINs assigned to citizens and permanent residents, because they have an expiry date (which usually coincides with the expiration of the holder's work authorization). These SINs are invalid unless there is an expiry date listed on the card and the date has not passed.
[edit] Analysis
Social Insurance Numbers can be validated through a simple
check digit process called the
Luhn Algorithm.
046 454 286 <--- A fictitious, but valid SIN 121 212 121 <--- Multiply each top number by the number below it.The result is:
086 858 276Notice that, in the second-to-last column, 8 multiplied by 2 is equal to 16. In the case of a two-digit number, simply add the digits together (1 + 6) and insert the result (in this case, 7). When writing a program to complete this task, minus 9 might be simpler to implement (in this case 16 - 9 = 7).
Then, add all of the digits together:
0+8+6+8+5+8+2+7+6=50If the SIN is valid, this number will be evenly divisible by 10.
[edit] Geography
The first digit of a SIN indicates the province in which it was registered:
1: Atlantic Provinces:
Nova Scotia,
New Brunswick,
Prince Edward Island, and
Newfoundland and Labrador 2: Quebec 3: Quebec 4:
Ontario (including overseas forces) 5:
Ontario 6: Prairie Provinces (
Manitoba,
Saskatchewan, and
Alberta),
Northwest Territories, and
Nunavut 7: Pacific Region (
British Columbia and
Yukon) 8: Not used 9: Temporary resident 0: Not used (Canada Revenue may assign fictitious SIN numbers beginning with zero to taxpayers which do not have SINs)
Note: While the first digit usually identifies the location of registration, the government has found it necessary in the past to supply certain regions with SIN numbers assigned to other regions.
