The serial number system is still being used on badges from about five or so years ago, and I'm quite sure the numbers are assigned and maintained by IHQ. I'm guessing at the system/methodology but the first set of numbers would designate chapter (installed in chronological order I assume), the second identifies the individual within the chapter in the chronological order she was initiated.
Well, my badge says AQ363. I was initiated into Epsilon Alpha chapter (which would have been Alpha Alpha if AGD did not use regional designations) and the chapter roll was over 800 initiates by then.
I logged into MyAlphaGam and didn't see any membership number (such as would be on the Quarterly mailing label).
