1. How does your zip code data differ from USPS data?
USPS data is the main foundation for our zip code data. As they update their data every month we provide the updated data to our customers. However, our data is more accurate and extensive as we append additional fields to improve the data for our customers.
2. Why should you choose ZIP Code Download over its competitors?

We make our database useful and user friendly by enhancing with additional data such as area codes, latitude and longitude coordinates, and MSA Codes. Many of our competitors rarely update their data and use data that is months or even years old.

4. How are Latitude and longitude calculated?
Most latitude and longitude coordinates are centroid based. In other words, they're in the exact "center" of the ZIP Code. In cases where the ZIP Code includes a large unpopulated area, the coordinates may be population based.
5. What does Zip Type mean?
The USPS has assigned each ZIP Code a "type". Why? It helps them sort mail more quickly.
S - Standard - A "standard" ZIP Code is what most people think of when they talk about ZIP Codes - essentially a town, city, or a division of a city that has mail service.
P - PO Box Only - Rural towns, groups of towns, or even high-growth areas of cities are given a "PO Box Only" ZIP Code type.
U - Unique - Companies, organizations, and institutions that receive large quantities of mail are given a "unique" ZIP Code type.
M - Military - Military bases overseas - and often vessels and ships - are given a "military" ZIP Code type.
6. What does City Type mean?
In many cases, a ZIP Code can have multiple "names", meaning cities, towns, or subdivisions, in its boundaries. However, it will ALWAYS have exactly 1 "default" name.
D - Default - This is the "preferred" name - by the USPS - for a city. Each ZIP Code has one - and only one - "default" name. In most cases, this is what people who live in that area call the city as well.
A - Acceptable - This name can be used for mailing purposes. Often times alternative names are large neighborhoods or sections of the city/town. In some cases a ZIP Code may have several "acceptable" names which is used to group towns under one ZIP Code.
N - Not Acceptable - A "not acceptable" name is, in many cases, a nickname that residents give that location. According to the USPS, you should NOT send mail to that ZIP Code using the "not acceptable" name when mailing.
7. Can I redistribute your data with my software?
