• 309 685 4195 – childhood home phone.
• 312 802 1902 – my old desk phone at wwa
• 3-0003 – the helpdesk phone number when i was a student employee for the ADN at UIC
• 312 259 4193 – my first cell phone, which i picked because the last four digits were close to my childhood phone number, but which i could never remember the prefix of (and kept giving it as 253, which really just led to more confusion) for a very long time.

and, honorable mention (since this is such a short lists entry): license plates!

• IL KE 2125 – my mom’s license plate for like 15 years
• IL VIV NIN 1 – my first license plate, back when i really really liked nine inch nails. I WAS SIXTEEN; SHUT UP.
• IL 563 something – my first plates on the passat, before i got breast cancer plates
• IL 4280 – current plates. i am never sure if the “CD” plate class designation is a part of the plate number or not (i.e., if my plate number is officially “4280” or “4280 CD”), which led to much confusion during the stolen car incident. amusingly, none of the police officers with whom i spoke seemed to know either!
