Was hoping this might help someone in their research.......sorry if it's off-topic....<g> Diana Decoding the Social Security Number (from "Social-Security-Numbers And Other Telling Information:" by Simson Garfinkel, published in the Whole Earth Review, Fall 1989) The first three digits of a person's Social Security Number indicate the state that the person was living in at the time the number was assigned (see table). The exceptions to this rule are numbers in the 700-729 range, which were issued by the Railroad Retirement agency, the only such retirement plan to have its own block of SSNs. The fourth and fifth digits indicate the group number. The sequence is reported to be odd numbers from 01-09, then even numbers from 10-98, then even numbers 02-08, and finally odd numbers 11-99. All numbers issued before 1965 are either odd numbers between 01 and 09, or even numbers between 10 and 98. The last four digits are the "serial number," and run from 0001 to 9999... 001-003 New Hampshire 004-007 Maine 008-009 Vermont 010-034 Massachusetts 035-039 Rhode Island 040-049 Connecticut 050-134 New York 135-158 New Jersey 159-211 Pennsylvania 212-220 Maryland 221-222 Delaware 223-231 Virginia 232-236 West Virginia 232 N.
