The Do Not Call Registry is a national list that allows consumers in the United States to opt out of receiving unsolicited telemarketing calls. Managed by the Federal Trade Commission (FTC), individuals can register their phone numbers to reduce unwanted calls from telemarketers.
Once a number is registered, telemarketers are required to remove it from their calling lists. However, some exceptions apply, such as calls from political organizations, charities, and companies with which you have an existing relationship. The registry aims to give consumers more control over their phone communications.
