Selective Service Number coding:
First number — state issued
Next two digits — local board
Next two digits — year of birth
Four group of digits — the registration number
From Page 248, The Complete Guide for CPP Examination Protection (pub 2006), via Google Books.
Correction — Last code should read “Fourth group of digits”
This doesn’t seem to fit the pattern you have below:
>>>His registration number is 61-1125539-1<<<
First number state issued
Next two digits local board
Next two digits year of birth
Four group of digits the registration number
I’m trying to find what the state number codes are. Is that public information?
