Internal Do-Not-Call List

An internal do-not-call list is a company's own record of people who asked that company to stop calling them.

Separate from the National Do Not Call Registry, every company that makes telemarketing calls must keep its own do-not-call list. If someone tells your rep, or your AI agent, "please don't call me again," that number goes on your internal list. It applies even if the number is not on the national registry and even if the person once gave consent.

FCC rules at 47 CFR 64.1200(d) set the basics:

• Have a written policy for maintaining the list, available on request.
• Train everyone who makes calls on how to use it.
• Record requests and honor them within a reasonable time, not more than 10 business days from the request.
• Honor a do-not-call request for 5 years from when it was made.
• Share the request across the calling entity, so a stop request to one campaign stops the others.

Practical tips: make "add to do-not-call" a one-click disposition, sync it to your CRM and every dialing tool, and include requests from email, text, and web forms, not just calls. Check the list before every campaign, not just once. A stop request that slips through is one of the most avoidable compliance mistakes in outbound calling.
