One should not make too much of the "geographical code." It is not meant to be any kind of useable geographical information. The numbering scheme was designed in 1936 (before computers) to make it easier for SSA to store the applications in our files in Baltimore since the files were organized by regions as well as alphabetically. It was really just a bookkeeping device for our own internal use and was never intended to be anything more than that.
why dont you read a little further in the thread before throwing your hissy fit. And FYI social security numbers and where they were obtained is a tool of law enforcement and used all the time. Many officers are even given cards with each block of numbers and the state of issue (describe it as you care to) so stfu.
