What is the DNC Registry?

The National Do Not Call Registry was started by the Federal Trade Commission - FTC as a way to protect consumers from unwanted sales calls. Registering is free and anyone can sign-up by visiting and registering their number.

The Federal Trade Commission post this warning to consumers "Most legitimate companies don't call if your number is on the Registry. If a company is ignoring the Registry, there’s a good chance that it’s a scam. If you get these calls, hang up and file a complaint with the FTC."

What is Do Not Call List Scrubbing?

DNC list scrubbing is a way of identifying numbers that have signed up to be on the federal, state, or Direct Marketing Association’s Do Not Call lists. Without conducting a DNC lookup, telephone numbers listed on any of the DNC lists could easily be dialed, putting your organization at risk for fines and penalties. It doesn’t matter if the call was placed intentionally or by accident - you will be held responsible.

What is a Subscription Account Number (SAN)?

A Subscription Account Number or SAN is the number that identifies an organization that has agreed to abide by regulations set forth by the FTC and has registered for an annual subscription to the Do-Not-Call Registry. RealPhoneValidation requires that you enter your SAN before submitting your DNC check.

Who needs a SAN?

Any organization that is selling or marketing services or products by telephone.

DNC Check Best Practice Recommendations

  • Create a written DNC policy containing detailed information on proper do not call procedures for your staff.
  • Maintain an organization specific internal DNC list file that you can add individual numbers to if requested
  • Do not validate more numbers on your calling list then you will call within 30 days of validating. If a number enters the list you have a safe harbor or grace period of 30 days if you can prove that the number was checked.
