Varying mailing address confuses Tosa reader

Issue: A reader noticed that sometimes her mail lists Wauwatosa as the city and other times it lists Milwaukee. She wants to know why this is.

Status: Sean Hargadon, spokesman for the U.S. Postal Service, explained that this is partially because Wauwatosa is a branch of the Milwaukee Post Office and Milwaukee services the area. But, the important part of the address is the ZIP code, he explained. As long as the ZIP code is correct, the city name doesn't really matter.

He added that ZIP codes don't always coincide with municipal boundaries. Some ZIP codes serve multiple communities, and sometimes a single community will have multiple ZIP codes within it, he said.
