Do Not Call List Lookup

DNC Lookup – Do Not Call List Lookup
The TCPA & Do Not Call Compliance Solution

When choosing a DNC (Do Not Call) service to minimize TCPA (Telephone Consumer Protection Act) violation risks, remember to check all three U.S. DNC lists, as calling a number on any of these lists constitutes a violation.

Also, check the Known Litigator list to identify repeat plaintiffs responsible for approximately one-third of all TCPA lawsuits. This step is crucial for reducing exposure to TCPA-related risks.

In addition to the points above, our Do Not Call Lookup includes information about the phone type, such as mobile, landline, or VoIP.

Be safe, stay compliant!

How to use DNC scrubbing tool
How to use the DNC checker tool

DNC Lookup checks the National Do Not Call Registry, and all states do not call lists, Direct Marketing Association Telephone Preference Service (DMA TPS), TCPA Known Litigator List, and phone type. DNC Plus includes DNC Lookup plus connected/disconnected status.

What is the DNC Registry?

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

The Federal Trade Commission posted 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 identifies 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 Checker 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 so you can add individual numbers if requested.
  • Do not validate more numbers on your calling list than you will call within 30 days of validating. If a number enrolls in a DNC list, you have a safe harbor or grace period of 30 days if you can prove that the number was checked.
