The US Zip Code Distance API is a solution designed to provide fast, accurate, and reliable distance calculations between ZIP codes within the United States. It allows users to easily integrate geographic distance information into their applications without having to handle complex cartographic data or proprietary geolocation algorithms.
When receiving one or two ZIP codes as parameters, the API returns the exact distance between both points using standard units such as miles or kilometers, as requested by the user. Its optimized architecture guarantees responses in milliseconds, accompanied by essential metadata such as timestamp, response time, and uniform payload structure, which facilitates monitoring and debugging in production environments.
The API is ideal for a wide variety of use cases. Logistics and transportation companies can calculate estimated routes or classify shipping zones. E-commerce platforms can determine distance-based costs or choose optimal warehouses for shipping merchandise. Land-use planning, market analysis, insurance, and coverage service applications can obtain accurate data to estimate proximity, risk, or operational reach. Even academic projects or mobile applications can benefit by obtaining fast distances without the need for local GIS systems.
In summary, the US Zip Code Distance API simplifies access to distance data between zip codes, offering speed, accuracy, and ease of integration. It is an essential tool for any solution that requires geographic calculations within the United States, providing clear, consistent, and ready-to-use information for modern applications.
Calculate the exact distance between U.S. ZIP codes, delivering fast, accurate, and structured results.

To obtain your API key, you first need to sign in to your account and subscribe to the API you want to use. Once subscribed, go to your Profile, open the Subscription section, and select the specific API. Your API key will be available there and can be used to authenticate your requests.
You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.
If you don’t cancel before the 7th day, your free trial will end automatically and your subscription will switch to a paid plan under the same plan you originally subscribed to, meaning you will be charged and gain access to the API calls included in that plan.
The free trial ends when you reach 50 API requests or after 7 days, whichever comes first.
No, the free trial is available only once, so we recommend using it on the API that interests you the most. Most of our APIs offer a free trial, but some may not include this option.
Yes, we offer a 7-day free trial that allows you to make up to 50 API calls at no cost, so you can test our APIs without any commitment.
Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs. Once you sign up, you can pick and choose which APIs you want to use. Just remember, each API needs its own subscription. But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.
