Using search engine techniques, conventional mailing lists and other relevant business data our dedicated research team manually searches on the web to find each business listed. When found they visit that business’s website to confirm and verify details such as business activities and other relevant data such as email address.

Then every few months in order to keep the resulting data up to date we send a verification email to all the addresses in our database and we simply delete out any addresses that are invalid or that bounce and we then amend records accordingly.

In addition all Postal Addresses are submitted for CASS  verification against the USPS database which returns highly accurate 9 digit Zip Codes for the vast majority of addresses.
