The Do Not Call List is a registry of phone numbers that consumers can add their phone numbers to if they wish to stop receiving telemarketing calls. This list is managed by the Federal Trade Commission (FTC) and was created in response to the increasing number of unwanted telemarketing calls received by consumers. The list is available to both landline and mobile phone numbers, and telemarketers are required by law to check the list before making any sales calls. If a consumer's number is on the list, telemarketers are not allowed to call them, unless they have received prior permission to do so. The Do Not Call List is an effective tool for consumers who wish to reduce the number of unsolicited sales calls they receive and is a great way to protect your privacy and avoid unwanted interruptions.
