The National Do Not Call Registry is a free, federal database managed by the Federal Trade Commission (FTC). It lets consumers opt out of most telemarketing calls. As of 2025, over 254 million phone numbers were registered, including both landlines and cell phones. The registry applies to any telemarketer calling a US number; violators can face fines up to $50,120 per call under the Telemarketing Sales Rule. Registration does not expire, so you register once and remain protected indefinitely unless you remove your number.
How to Register Your Cell Phone
You can register your cell phone number online at the official FTC Do Not Call website or by calling 1-888-382-1222 from the phone you wish to register. The process takes less than two minutes. After 31 days, telemarketers must stop calling. There is no cost, and you do not need to renew. If you receive calls after that period, you can file a complaint with the FTC. For cell phones, the registry works exactly the same as for landlines—there is no separate mobile registry.
| Registration Method | Time to Effect | Cost |
|---|---|---|
| Online (DoNotCall.gov) | 31 days | Free |
| Phone (1-888-382-1222) | 31 days | Free |
What Calls Are Still Allowed?
The registry does not block all calls. Exemptions include:
- Calls from political organizations, charities, and surveyors.
- Calls from companies you have an existing business relationship with (up to 18 months after your last purchase or payment).
- Calls for which you have given prior written consent.
- Non-telemarketing calls, such as debt collection or informational messages.
Enforcement and Limits
The FTC and the Federal Communications Commission (FCC) share enforcement. The FTC brings civil lawsuits against violators; the FCC can impose fines and revoke licenses. In 2024, the FTC reported over 4.5 million complaints about unwanted calls. However, enforcement is challenging because many violators use caller ID spoofing or operate from overseas. The registry is a deterrent for legitimate businesses but not a complete shield. The FCC’s STIR/SHAKEN protocol, which authenticates caller ID, has reduced spoofed robocalls but not eliminated them. Consumers should combine registry registration with call-blocking apps or carrier-level filters for best protection.
Additional Protections in 2026
As of 2026, major national carriers offer free robocall-blocking tools that integrate with the Do Not Call Registry. The FCC has expanded STIR/SHAKEN to cover smaller providers, closing a loophole. The Telephone Consumer Protection Act (TCPA) allows consumers to sue for up to $500 per unsolicited robocall (or $1,500 if willful). To maximize protection:
- Register your cell number on the Do Not Call list.
- Enable your carrier’s free spam-blocking feature.
- Install a third-party call-blocking app (many are free).
- Never answer calls from unknown numbers; let them go to voicemail.
