secret

i am going to post something which i dun know why can it be found out. nt sure if there's anything wrong with posting or not.. but well.. if I can derive... what's the secret? haha.. okok.. if i can found the person to derive...

How are Singapore IC Numbers calculated and produced? No,
they do not come randomly. There is a system, and I am going to show it
to you now.

Let's take this IC number as an example:

S8706407G

Firstly, what does S stand for?

And why are the babies born in 2000 onwards have the prefix “T”


Contrary to common perception, S does not stand for "Singapore"
and T is not used because they ran out of "S"s to use.

S is the 19th character of the alphabet, so this person is born in the
1900s.

What does "87" stand for, then?

Obviously, Singaporeans can observe from their own IC numbers that 87
would stand for the year the person is born, so this person is born in
1987.

The last 5 digits "06407" means that this person is the 6047th
baby to be born in the year 1987.

Finally, how does the letter G come about? Here is the answer.

First, the numbers are put through a weightape, which is the same for
every number:

Number	8	7	0	6	4	0	7
Weightape	2	7	6	5	4	3	2
Result	16	49	0	30	16	0	14	Sum: 125

So we have the number 125.

Divide 125 by 11

Answer: 11r4

11-4=7

Put the number 7 throught the conversion table:

Number	1	2	3	4	5	6	7	8	9	10	11
Letter	A	B	C	D	E	F	G	H	I	Z	J

Conversion Table

So you get the letter "G".

Ta-da! This is how the IC number S8706407G comes about.

P.S. This information does not apply to new IC numbers starting with
anything other than the letter "S".
