TCPA Compliance, Dialed In

Verify Telephone Numbers to Avoid Fines

Doing business over the telephone can be risky. Violations of the Telephone Consumer Protection Act (TCPA) carry serious penalties for offenders.  With the right information, it is possible to avoid these infractions and associated fines. 

This service, known as the Wireless Do Not Call (WDNC) service, allows you to verify if a consumer’s telephone number is wireless or wireline.  Without it, your business may be in violation of the TCPA regulation that prohibits the use of autodialers or pre-recorded messages to any telephone number in which the called party is charged.  With this service, you can simply and securely download this information via a web-based portal, which includes wireline to wireless porting data (with or without ranges) and wireless to wireline porting data (with or without ranges).


Businesses that must comply with the Telephone Consumer Protection Act and rely on the WDNC service for porting data can register today.
