E-commerce websites, logistics portals, and other solutions with address verification need to automate the validation process. Automation allows product teams to avoid manual address form validation and enhances user experience. Customers instantly see whether the details they provide are valid, which prevents misdeliveries, declined payments, lost orders, and other issues.

An information address validation API is a timesaving approach to get address form validation in your website or app. You don’t have to overload your engineering team with custom address parsing and validation development. Address verification APIs allow them to implement the necessary functionality in several days. Once they finish, automated data checks become a part of your software capabilities and work as smoothly as native features.

Even though validating addresses with an API is easy, you should be aware of some technical nuances. They affect the quality of automated address form validation and help to ensure address validation APIs are properly integrated.

This article shares tips on integrating information address validation APIs. Use them to automate real-time address form validation.

What Is an Information Address Validation API and How Does It Work?

Like any API, an information address validation API connects two applications, a third-party address verification platform and your software. It’s an interface that allows you to layer automated address parsing, address formats standardization, matching, validation, and enrichment into existing solutions.

After the integration, the API manages postal address data processing with requests. For example, when a user enters their contact details in the website form, the website triggers the API to complete address form validation. The API forwards this request to the address lookup and validation software that matches the data and returns the result.

Benefits of Information Address Validation API Integration

Engineering teams implement software functionality using APIs whenever they can. APIs offer a simpler and more cost-effective way to get the necessary features out of the box.

Information address validation APIs are particularly popular since custom development of such solutions is counterproductive. You will need to get CASS certified by the United States Postal Service, take data security precautions, and waste resources on software maintenance. Information address validation API saves you from these problems.

Address Validation API

Apart from the practical benefits, the address form validation API has some business advantages:

Digital transformation

To fully transform their business, companies need to ensure software interoperability and advanced automation. A batch and single address verify API is an essential part of this process in many industries. When you use a software solution developed specifically for address form validation, you can be sure about its quality. Such software minimizes the risk of data processing mistakes and, hence, makes your database complete and accurate.

Top-notch quality

When you use a software solution developed specifically for address form validation, you can be sure about its quality. Such software minimizes the risk of data processing mistakes and, hence, makes your database complete and accurate.


Using an information address validation API, you can run a single address verify request or process batches with equal ease. The API provider manages the data processing load and allows you to scale as your business needs grow.

Most importantly, API integration allows you to release the product sooner and optimize the software development lifecycle. It gives a competitive advantage and enables product teams to speed up the market launch and start capitalizing on the developed software.

Who May Need Information Address Validation APIs

Now, when you know why to run single address verify requests with an API, make sure automated address checks are for you. There are several types of businesses and organizations that need automated address form validation:

  • E-commerce solutions
  • Logistics companies
  • Businesses that run AVS checks
  • Companies that use direct mail for delivery or marketing
  • Healthcare organizations
  • Utilities
  • Financial companies

All these entities have something in common. They run websites or applications that ask users to share address information at the point of entry and deliver communications by mail. They may also verify address data to run identity verification for financial operations and fraud prevention.

6 Tips to Successfully Integrate an Information Address Validation API

As a provider of an address form validation API, we know the most common integration mistakes. The following tips should help you avoid them and integrate any information address validation API at the first attempt.

#1. Understand What Kind of API You Need

Information address validation APIs fall into two categories: cloud and local. Companies with strict policies that cannot use cloud-based verification services may choose to install an API locally. Usually, these are enterprises that already have the necessary hardware. The local installation creates additional requirements for your server and involves the responsibility for server and network maintenance. Hence, the majority of other organizations, including SMEs, utilize cloud solutions. They are more common and easier to implement.

Understanding the API type, you identify what software is better for your organization and how to implement it. Besides, the functionality of address verification APIs varies. Whereas some solutions only verify data, others provide address autocomplete, enrich records with city and state, check international addresses, and more. It’s better to consider such peculiarities from the start.

#2. Ask the Software Provider for Tech Support and Documentation

Vendors that offer application programming interfaces can help with integration. They also share step-by-step tutorials, documentation, and other materials with guidelines. Never hesitate to contact the selected address verification vendor and ask for assistance.

Tech Support

Even though cloud-based address form validation APIs are easy to integrate, each API will have special installation instructions. Don’t forget to request them.

#3. Know the Technical Aspects of Integration

Before connecting an information address validation API, learn the dos and don’ts of integration. As a rule, you shouldn’t hardcode IP addresses and SSL certificates. It’s important to use trusted certificate authorities, meet HTTP, URI, XML, JSON specifications, and complete integration in modern browsers (e.g., Chrome, Firefox, Edge, Opera). You should also utilize modern cipher suites, cryptographic protocols, and security software.

#4. Save Your API Key Securely

Setting up automated address verification, you will need to provide your unique API key. It’s available in your dashboard once you register. Be sure to store the key following the best security practices. When the credentials are publicly exposed, attackers are more likely to compromise your account.

#5. Assign User Roles

Postal address data belongs to confidential information and, therefore, must be well-protected. We recommend creating teams with different levels of permissions once you finish API integration. This way, you will be able to manage access to the verification functionality and confidential details. But note that not all information address validation APIs support user roles.

#6. Test a Single Address Verify and Batches

Run real-time address validation to check how the connected API handles single and batch requests. It should automatically parse, standardize, match, and update addresses. If any of these processes fail, contact your API provider to get help with troubleshooting.
