Thanks! Yeah I try to find as many low #s (0-9999) as I can and put them in order, like people do for Delaware, just seeing how many of the slots I can get filled in
00 (“Null-Null”, double zero) is a code for public toilets, particularly common in Germany and Eastern Europe. According to Wikipedia, this originates from the room numbering system as used in hotels in the 19th century. The toilets usually were located near the elevator or the stairwell, so these “non-rooms” received the non-number 0, or 00.
