A postal API is a way to access address data from the US Postal Service. Unlike traditional postal services, the USPS has made its postal APIs available for public use. These APIs are not designed for a standardized database of addresses or to merge address data.

They also do not support the check of more than a few addresses at one time. But despite its shortcomings, USPS API developers have made the process easy to use by providing example code. Developers can start using the API in a matter of hours. APIs are available for JavaScript, C#, iOS, and Python.

PostSave’s Postcard API

Address verification is a critical part of marketing, as a misdirected package can result in wasted time, packing materials, and even postal charges.

Imkite’s Address Validation / Standardization API

If you are a developer and need an easy way to validate addresses, you can use Imkit’s Address Validation / Standardsization API. It can process address information and returns deliverability status. The Address Bulk Verification API can handle up to 100K addresses and is asynchronous, sending a notification by email, HTTP, or taskid if the address is not delivered. Address Auto-Complete API returns addresses that match the input freeform address.

The Address Validation API is designed to correct invalid addresses and facilitate faster delivery of packages. It can be used to validate recipient address information by comparing it with reference data. It can also be used to validate and correct address information that contains erroneous information, such as an incorrect postcode. The Address Validation API supports addresses from the U.S. and Canada, and it receives monthly updates to the address database.

USPS Web Interface

When you’re integrating your website with the USPS Web Interface, you might encounter an error message saying that the authorization failed. This error message is usually associated with a number of reasons, such as lack of sample code and documentation. In addition, the API is only available for individual transactions. Therefore, you can’t use it for batch processing or database cleansing. In the end, you’ll have to write your own code from scratch, which requires significant time and effort.

Another feature of the USPS Web Interface is that it is completely free. While many service providers provide free address lookups, none of them is truly free. The USPS interface allows you to enter valid addresses and receive notifications when they’re invalid. However, you can only use the interface to verify a single address. If you need to validate a large number of addresses at once, you may want to look for a more cost-effective solution.
