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 this important?

It stops your company from wasting money on mailing to addresses that do not exist or from shipping a product to an 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.

DataTools’ OptiSource System™ uses quality information from multiple suppliers to ensure the integrity of the data provided. By pulling data from the very best, leading data quality sources in over 245 countries and territories, we can provide you with the most accurate address validation software available. International data cleansing helps deliver your shipments and mailings on time and to who and where the shipment is expected.

In Australia, DataTools uses the Postal Address File (PAF), the Geocoded National Address File (GNAF), and GNAF Live. Each of these organisations specialise in a different type of address verification. 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.

In New Zealand, we use the Postal Address File, the New Zealand Address Dataset (NZAD) and Land Information New Zealand (LINZ). By cross-referencing the multiple databases, we can provide the most accurate information available.
