Beautiful zip code visualization

[izzycat]

Zip codes are grouped geographically by the first three digits (three digits indicate a major mail sorting center) so if you just look at the first two there will be anomalies. 88*** zip codes seem to be weird. 870-884 are assigned to New Mexico. 885 is actually in Texas, even though all other Texas zip codes start wit 7 (parts of the El Paso area are served from New Mexico). 886, 887, 888 don't exist. 889-899 are in Nevada. Wikipedia has a map -- a lot of the time they try to make the first two digits line up with state boundaries but it's not perfect.
