Zip codes are a type of postal code used in the United States, created in the 1960s to make mail delivery faster and more efficient.
A standard zip code is a five-digit number, and today the US Postal Service uses a “ZIP+4” code, consisting of the zip code and an additional four-digit number for even more accuracy.
Zip codes are very important for any website, app, or program that needs to look up or verify mailing addresses.
An API is a shortcut developers can use to connect their code to applications with existing zip code functionality.
Most zip code APIs work by gathering a specific zip code from an external program, either manually or via a map or other user interface, and performing some kind of operation on them. The results of the operation are then returned to the originating program, where they can be accessed by the end-user.
Developers of software that delivers localized information to users can benefit from an API that delivers information about or based on zip codes.
Other users might include authors of mapping software, developers of a web-based storefront plugin for WordPress, and anyone else who needs to find information about a specific geographical area in the United States of America.
One important benefit of a free API is the cost.
However, free APIs are also important because they are likely to be written in as transparent a manner as possible. This makes it easy to connect other software to the functionality they provide, and also reduces research time.
APIs typically request information from external programs via GET or POST requests. They then return data in a JSON or XML format that can be accessed directly by the requesting program.
All zip code APIs are supported and made available in multiple developer programming languages and SDKs including:
