How long does the Do Not Call list last?

Your registration will never expire. The FTC will only remove your number from the Registry if it’s disconnected and reassigned, or if you ask to remove it.

The National DNC Registry requires you to re-scrub your list every 30 days to maintain a current status.  However, state regulations may vary, please consult the official state websites.

Can the Scrub DNC software handle phone numbers in different formats?

Yes. Scrub DNC can compare lists even if the numbers are in different formats.

  • 314 555-1234

  • (314) 555-1234

My phone numbers have non-standard separators in them (ex: 636%296%5555).  Will that affect how Scrub DNC cleans my list?

Scrub DNC is designed to work with and handle non-standard characters in your lists.  However, for best results, please clean your list of any non-standard characters (see list of supported phone formats above).

How long does the Scrub DNC software take to scrub a list?

Scrubbing times will vary depending on the number of call lists and DNC lists being scrubbed and how clean the lists are.

What if I accidentally call a number on the DNC list?

A lawyer should be contacted for all legal advise. For your convenience, Scrub DNC outputs scrubbing logs so that you can verify that you acted in good faith as well as, if Scrub DNC was properly used, the telemarketer may fall under the "Safe Harbor" protection as outlined by the FTC in this document.
