Insurance number social (Canada)

A insurance number social (NAS) is a number emitted with the Canada to manage various governmental programs.

The NAS was created in 1964 to be used as account number customer in the administration of and several the program pension plans of insurance employment. In 1967, which is today the Agency of the income of Canada started to use the NAS for paiment of taxes. The NAS are emitted by the Development of human resources Canada.

The NAS is a succession of three groups of three digits each one (for example 123-456-789).

Although not conceived for that at the base, the NAS became de facto a national identification number, just like the social security number with the the United States or in France. However, contrary to that of the United States, this number can be used only with particular aims; unless an organization can prove that the reason for which they ask a person her NAS is expressly authorized by the law, or which no other document proving the identity could be enough to carry out an operation, it will not be able to prohibit or refuse a product or a service while being based on the refusal of the person to provide her NAS.

Insurance numbers social starting with the figure " 9" are allotted to the nonCanadian temporary residents (foreign students, detached workers). These people must have an authorization of work to work in Canada. These particular NAS have a scratch date (which often coincides with the end of authorization of work). They are valid only if this date is not exceeded.

Analyzes

The NAS can be validated by a simple checking of the numbers:

046.454.286 <--- Example of fictitious but valid NAS 121.212.121 <--- One multiplies each figure of the NAS by the figure of the same column of the number opposite.

The result is:

086.858.276

To note that for the penultimate column, 8 multiplied by 2 must give 16. In this case where the result of the multiplication is a number with two digits, one adds the figures of this number between them and one preserves only the result here (: 16 become 1 + 6 = 7).

Then, one adds all the figures found between them:

0+8+6+8+5+8+2+7+6 = 50

So that the NAS is valid, the result must be able to be entirely divided by 10 (not of remainder of division).

Geography

The first figure of the NAS indicates the province where it was allotted:

1: Atlantic Provinces (Nova Scotia, New Brunswick, Island-of-Prince-Edouard and Ground-New-and-Labrador

2: Quebec

3: Quebec

4: Ontario (foreign forces included)

5: Ontario

6: Provinces of the meadows (Manitoba, Saskatchewan and Alberta), Territory-of-North-West and Nunavut

7: Peaceful area (Colombia-British and Yukon)

8: Not used

9: Resident temporary

0: Not used (the Agency of the Canada income can assign fictitious NAS of this type to the taxpayers not having a NAS)

Note: the government sometimes delivered in certain areas of the NAS whose first figure corresponded to another area.
