USPS Address Verification Software

USPS address verification software helps your company improve the effectiveness of its mail and other communication channels. When mailing out promotional material, it's essential to ensure that your letters and packages are delivered to their destinations. Using USPS verification tools can help you reduce the amount of lost mail and late deliveries.

The USPS (United States Postal Service) maintains a database of about 160 million addresses. These addresses are compiled and made available through official APIs. This type of database is useful in a number of applications, including web forms and email campaigns. It also makes it possible to check the zip code of a certain address.

The USPS API is a handy tool for developers. The information that the API provides can be used to check thousands of addresses at once. However, the documentation is a bit of a mixed bag. While the documentation is informative, it can be overwhelming.

On the other hand, the USPS website offers a free online address validation service. In addition to verifying your address, the system displays a thumbs up or down indicating whether the address was successfully verified.

Using this information can help you avoid costly returned deliveries. Addresses that are invalid will require repackaging and additional postage.

For those that aren't sure about using the USPS API, there are third-party companies that offer solutions that are less restrictive. Typically, these providers will allow you to process your address list in a variety of formats, such as Excel or CSV.
