If you’re developing a web application that uses USPS’s address autocomplete API, you’ll want to use its schema to avoid errors and provide a valid response to users. USPS address verification API are generally accepted, though errors and typos can occur. When an address is submitted in error, the USPS will attempt to correct it by adding “ST” to the address or changing Suite to STE. It will also correct the ZIP code if it’s incorrect.

There is no documentation for the USPS address autocomplete api. While the USPS APIs are free, they do not have many features to support high-volume address validation. These problems make them unsuitable for many applications. Thankfully, there are API solutions to solve these problems that are affordable, reliable, and easy to use. However, before you start coding, read the documentation carefully. The following are some of the main features that you should look for in a USPS address autocomplete API.

USPS APIs are free to use once you’ve registered for an account. The APIs are only for individual transactions, and they do not work for database cleansing or batch processing. If you’re using an API with the USPS, be aware that it may be suspended or discontinued without notice. It’s best to consult documentation before using an API, especially if your application is built to integrate with their shipping services.


If you’re looking for an address autocomplete API, USPS has many options to choose from. Some of the top providers are Melissa Data, and Loqate. The advantages of each provider range from uptime and tech support to ease of use. Each service provides different levels of accuracy and supplemental information. The USPS API is known for its uptime and extensive international data, while Melissa Data is a popular choice for address validation. Using Loqate is a great choice if you’re comfortable reading API documentation and working independently.

USPS Web Interfaces allow users to validate addresses one-at-a-time and give a thumbs-up or down after confirming the accuracy of the address. You can also integrate the USPS address validation API into your website to ensure high quality address data. These services are used by a variety of online businesses, including healthcare organizations and financial institutions.


USPS address autocomplete APIs can be difficult to use and have numerous limitations. Depending on the type of address you are trying to find, you might be limited by the amount of addresses you can find. You will also need to implement a license agreement and abide by technical limitations, like a limit on the number of calls per day. These limitations can be frustrating, but they also limit how much you can use the system.

One of the most significant shortcomings of USPS address autocomplete API is its limited data set. Unless you are using the USPS address autocomplete API to validate addresses, you are limited to entering valid addresses. The address validation feature allows you to verify a single address, but is not suitable for bulk validation or database cleansing. You should only use USPS address validation APIs in conjunction with USPS shipping services. This is because the USPS address database has millions of valid addresses, but there are limitations that make it difficult to use in bulk.
