Choosing the Best Address Verification Tool

Address verification is an integral part of many successful business models. The address is one of the most important customer details which is subject to many errors.

From mistyped street names and lost zip code digits to outdated details and improper formats, invalid addresses cost companies millions of dollars.

An address verification tool helps solve these problems by identifying typos, format issues, invalid data, and more. Adding address validation to your tech stack helps to avoid these issues and their consequences.

Let’s take a closer look at choosing the best address verification software for your needs.

What Is an Address Verification Tool?

An address verification tool is software that helps your businesses verify the validity and accuracy of addresses. It uses a database or API to cross-reference the address data against reliable sources. For example, validating against postal records or commercial address databases. The tool checks for address completeness, correctness, and standardization.

The main advantages of using an address verification software for your company include:

Higher Data Quality

By enhancing customer master data quality, this tool improves your data analytics results. Since the address carries important demographic data, it can become an integral element of your marketing and sales campaigns.

Customer Satisfaction

The verification process must ensure the accuracy of customer data in order to reduce shipping errors, failed deliveries, or returned packages. By avoiding these problems, you can improve customer satisfaction and reduce customer service issues.


Using address verification software speeds up the address validation process by eliminating manual data evaluation and cleanup. This reduces unnecessary shipping and return costs created by invalid or incomplete addresses.

What to Consider When Choosing an Address Verification Tool

Since many companies offer address verification tools, it can be complicated to make a choice. Things to pay attention to when exploring the options include:


This is very self-explanatory. The address validation software needs to be very accurate and reliable in all countries and regions you plan to use it in. An accurate and reliable solution can help you dramatically increase your data quality and eliminate many problems associated with bad data quality.


Find out how many addresses the solution can handle as well as how fast it can process them. Even if you don’t need to check large volumes of address data today, the situation can easily change in the future.


Look for address validation software that easily integrates with your existing tech stack. If you want the solution to check for typos and errors in real-time, you need to make sure that it integrates well with your existing workflows.   

Find out whether the validator is an on-premise or a cloud solution. Cloud solutions are highly flexible and can be used at any time and from anywhere. They usually have attractive payment options and pricing structures too.

User-Friendly Interface

One of the key considerations is user-friendliness. The address verification software you choose should have a straightforward and intuitive interface. Your team should be able to start using it immediately.

Many tools have a free version that allows you to try how it works. Pay attention to the simplicity and user-friendliness.

Cost vs ROI 

Cost shouldn’t be the deciding factor, at the end of the day it is the ROI that really counts. Look at the pricing structure of the address verification tool and consider the value for your business vs the costs (ROI). While some tools charge per address, others have monthly or yearly plans. 

Real-Time Verification

Find out if the address verification tool can provide real-time results. It means that while the customer is typing the address, the tool is checking its validity. This can help prevent typos and keep customers from using non-existent addresses.


You don’t want the tool you choose to have downtimes during the busiest time on your website. Look for address validation software with a high uptime guarantee.


Reviews and testimonials from other users can provide valuable insights into the effectiveness of the address verification software of your choice. Read reviews from reputable sources like G2, Capterra (), or to understand the experiences of other businesses using the tool.

Data Security / GDPR

Since the tool will be handling personally identifiable information, you must choose a provider that takes good care of data protection and security. Find out how the tool complies with relevant data protection and security regulations in all the countries that your customers come from.

International Databases

If you are working with customers from different countries, review the ability of the tool to check out-of-country address data formats. Find out if the tool can handle overseas addresses and whether they contain location data for all the countries you need.
