Why your mail may say Portland when you live outside it
A letter addressed to Portland can go to a home outside the city limits, because ZIP areas follow delivery routes, not town lines.
The reverse happens too: parts of Portland use 04019, which mails under a neighboring town's name.
A ZIP code does not set your city, school district or tax. Cumberland County property records show which city you are in.
