Address validation
and verification

Your marketing and shipping dollars are too valuable to waste. Explore data cleansing and address lookup solutions to ensure every message and parcel reaches its destination, enhancing both your customer’s experience and satisfaction. 

Address verification involves checking a mailing address against an authoritative database to see if the address is valid. It is looking for undeliverable, fake, or incomplete addresses, and then fixing them through address validation. 

Why is it important?

Is address verification necessary?

It stops your company from wasting money on mailing to addresses that do not exist or from shipping a product toan incomplete address that is undeliverable. Postcode validation software and other forms of address verification software automatically detect these invalid addresses, saving you thousands of dollars on these mailing and shipping costs. Address validation tools increase efficiency by keeping your address lists accurate and up-to-date, saving you time and postage.

Undelivered mailings and shipments often result in customer frustration and poor customer loyalty. This, in turn, results in missed sales opportunities, poor customer satisfaction rates, and unnecessary time and costs to reship the mails. Address software tools ensure your important company communications and shipments reach your customers and potential customers by making sure you have accurate address data.

Data Quality Matters

When it comes to address verification, the quality of your results depend on the quality of the reference sources used to validate the data. DataTools uses solid data, quality software, and the best vendors and sources to provide you with the most accurate information available.

By combining the information from all of them into one quality data software, DataTools is able to bring you a highly accurate address verification system.
