Compliance, Dialed In

Wireline or Wireless?  Know before you call

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. 

One way to do so is by incorporating PortData Comply, the Wireless Do Not Call (WDNC) service, into your telephone number verification processes. This service allows you to verify if a consumer’s ported 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 voice 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). The PortData Comply service provides a critical piece of information to help you round out your company’s TCPA compliance efforts for telephone marketing. Have questions about which companies can access NPAC data and for what purposes?
