Post Office Identifier
Do you collect pre-cancels or postmarks?
Do you have trouble reading the city or state?
With the form below, you can enter as much of the city name as you can read
from the beginning, middle or end and (optionally) the state. If you know the
ZIP code, you may enter that instead of the city/state. The program will locate
all the cities (from a collection of more than 40,000) within the U.S. that
match the letters entered.
