IMDataCenter's phone append process gives you the ability to omit DNC Phones in real-time and append only the non-DNC phones with a SAN number. This is a great advantage because you only pay for phones where we match a callable number. We typically match 10%-15% when appending non-DNC phones and 40%-60% when appending DNC phones.

If you have an email address only we can reverse append a name and physical address and then phone append the data resulting in a complete marketing record with email with personalization, physical mailing address or phone number. Our clients use this process both for marketing communication as well as analytics and demographic appending.


IMDataBases can also reverse append a physical address and name using a 10 digit phone number on input. Our reverse append process includes Consumer Databases, Directory Assistance, Voice Over IP Phones and Wireless/Cell Phone Numbers. This helps maximize the match rate and provide quality addresses for you.


Customer Service at IMDataCenter is paramount and if you would like to self-serve on the website or have an account representative advise you and process your file for you we would love to help. We will provide a Free phone append match report to any new customer to prove out the value of our multi-pass process and if you have any questions please do not hesitate to call 800-531-2601 or click here to contact us.
