Validate Zip Codes With a ZIP Code API

The ZIP Code API provides an easy way to validate Zip codes. Using this technology simplifies demographic analysis, fraud detection, and global business processes.

The ZIP Code API uses JSON and XML response data to provide programmatic access to ZIP Code information. It also provides a full ZIP Code List retrieval. Those who develop localized software, web-based storefront plugins for WordPress, or any other system that needs ZIP Codes, can benefit from this free API.

ZIP Codes are four-digit code combinations that define a person's delivery location. They include latitude and longitude coordinates and are often converted into barcodes, which are easily scannable in post offices. These codes were introduced by the United States Postal Service in the 1960s to increase mail delivery speed.

When sending mail, it is important to use a valid ZIP Code. Incorrect codes result in longer shipping times and higher postage costs. Also, incorrect ZIP Codes can cause returns.

ZIP Code APIs can improve deliverability and prevent errors that can cost businesses time and money. They also can help streamline digital transactions. This means that they can be used in systems involved in communication, such as financial services providers and retailers.

If a user enters a ZIP Code in an online form, an API will auto-fill the fields. It can also convert the ZIP Code to a primary location.

ZIP code APIs also help make addresses more accurate. For instance, if the city or state in a submitted address does not match the city or state in the 5-digit zip code, a new address will be generated.
