Complete walkthrough of registering on the National Do Not Call Registry, what it covers, what it doesn't, and what to expect.
Registering on the National Do Not Call Registry is free and takes less than two minutes. There are two methods: online at donotcall.gov (the FTC's official site — do not use any other website), or by phone at 1-888-382-1222 (you must call from the number you want to register). Online registration requires your email address for confirmation; you'll receive a confirmation email and must click the link in it within 72 hours for the registration to take effect. Phone registration is immediate for the specific number you called from and requires no email confirmation. Both methods register the number on the national registry maintained by the FTC.
You can register up to three phone numbers in a single online registration session. Both landlines and cell phones are eligible for registration, though cell phones already have some protections from unwanted calls under the TCPA (Telephone Consumer Protection Act) that landlines do not. If you have a landline, a cell phone, and a VoIP home phone, register all three separately. Business phone numbers are not eligible for the Do Not Call Registry — the registry protects residential consumers, not commercial entities. Businesses have separate protections under various FTC telemarketing regulations.
Once registered, your number stays on the registry permanently — you do not need to re-register after a period of years. The FTC eliminated the five-year re-registration requirement that existed in the early years of the program; all registered numbers remain on the registry indefinitely until you request removal or the number is reassigned to a new subscriber (in which case the new subscriber must re-register). You can verify that your number is on the registry at donotcall.gov/verify.aspx. If your number has been registered, the site will confirm it and show the registration date.
The National Do Not Call Registry restricts unsolicited telemarketing sales calls from for-profit businesses selling goods and services to consumers. Specifically, it prohibits calls from: commercial businesses making sales pitches for products or services, survey companies that also sell products (the sale component makes them covered), debt collectors calling about consumer debts (though debt collection calls have their own separate rules under the FDCPA), and businesses that have solicited you previously but with whom you've asked not to be contacted. The registry applies to both live sales calls and automated prerecorded sales calls (robocalls) to registered numbers.
The registry's coverage extends to any business that has accessed the Do Not Call registry — which all compliant telemarketers are required to do before placing calls. Covered businesses must check the registry every 31 days and remove any registered numbers from their calling lists. A business that calls a registered number after the 31-day window has passed is in violation of the registry regulations and subject to FTC enforcement action. Civil penalties for violations can reach $51,744 per call (as of 2024, adjusted annually for inflation) — which creates substantial financial deterrent for compliant businesses and explains why most large US telemarketing operations respect the registry.
The types of calls covered means the registry is effective against legitimate businesses that are willing to follow the law. Established companies — major retailers, banks, credit card companies, insurance companies — that do telemarketing for legitimate products and services will remove your number from their calling lists when you're registered. The registry functions as intended for these callers. Where it fails is with callers who have no intention of following US law in the first place: scammers, overseas call centers, and fraudulent operations. These callers ignore the registry entirely, which is why registration doesn't eliminate all unwanted calls.
The Do Not Call Registry has significant legal exceptions that mean registered consumers still receive certain categories of calls. Political organizations and campaigns are exempt — federal law specifically excludes political calls from Do Not Call restrictions, which is why you receive calls from candidates and ballot measure campaigns even if you're registered. Non-profit charities are exempt — organizations with 501(c)(3) status can call registered numbers for fundraising purposes, though for-profit fundraising companies calling on behalf of charities are covered (a distinction worth knowing if you're curious about a specific call). Survey research organizations (those that don't sell anything) are exempt for conducting research surveys.
Companies with an "established business relationship" (EBR) with you can continue calling for 18 months after your last purchase or transaction, even if your number is on the registry. If you've bought something, subscribed to a service, or made an inquiry with a company, they can call you for the next 18 months. This EBR exception explains why you might continue receiving calls from your insurance company, bank, or a retailer you've recently purchased from even after registering. To stop these calls: tell the company during a call that you don't want to receive further calls and request removal from their internal calling list. This creates a company-specific "do not call" requirement separate from the national registry.
The registry does not block scam calls, robocalls from overseas, political calls, charity solicitation, calls from companies with whom you have an existing business relationship, or calls about debt collection. This is why registering eliminates some unwanted calls (from compliant legitimate telemarketers) but doesn't eliminate all unwanted calls. The complementary tools — call blocking apps like Hiya or RoboKiller, carrier-level spam filtering, and phone-level settings like Silence Unknown Callers on iPhone — address the categories the registry doesn't cover. Use the registry as one layer of a multi-layer defense, not as a complete solution.
After you register online and click the confirmation link in the verification email, telemarketers who are required to comply have 31 days to remove your number from their calling lists. The 31-day window is mandated by FTC regulation — telemarketers must access the registry at least every 31 days, and once they've accessed it and found your number registered, they must stop calling. In practice, this means you may still receive calls from covered telemarketers for up to 31 days after your registration takes effect, but the calls should stop after that window closes. Most large telemarketing operations update their lists more frequently — weekly or bi-weekly — so you may see a faster reduction.
For phone-based registration (calling 1-888-382-1222 from the number you want to register), the registration takes effect immediately in the registry database, and the 31-day compliance window begins from that moment. The practical experience of most registrants is a noticeable reduction in calls within the first few weeks, with near-elimination of covered telemarketing calls by the end of the first month. If you were receiving very high call volumes from covered telemarketers, the effect may be more dramatic; if most of your unwanted calls were already from scammers and exempt callers (political, charity), you may see less change.
If you've moved and gotten a new phone number, you'll need to re-register. New phone numbers are not automatically enrolled in the registry when issued. Additionally, if a phone number you've registered is disconnected and later assigned to a new subscriber, the registration is removed from the registry after the reassignment is detected — new subscribers must register their number themselves. If you switched carriers and kept your same number (ported it), your existing registry registration should transfer with the number, since the number itself is what's registered. If you're uncertain whether your number is still registered after a carrier switch, verify at donotcall.gov/verify.aspx.
If you're receiving calls from covered entities (for-profit telemarketers) after the 31-day window has passed since your registration, you can file a complaint with the FTC. The FTC's complaint process is at ReportFraud.ftc.gov — select "Unwanted Calls" as the complaint type. You'll need to provide the phone number that called you, the date and time of the call, what the company was selling or claiming, and whether the caller left any identifying information. The FTC uses these complaints to identify violators — they look for patterns of complaints against specific numbers or specific companies that indicate systematic disregard for the registry.
Individual violations also trigger FCC enforcement jurisdiction. The FCC's complaint center at consumercomplaints.fcc.gov handles robocall violations, spoofed caller ID complaints, and Do Not Call violations. Filing with both the FTC and FCC for a specific violation increases the chance of enforcement action. State attorneys general also have authority to enforce Do Not Call violations under state telemarketing laws — file with your state AG at the same time for maximum coverage. The National Association of Attorneys General (NAAG) maintains a list of state AG offices at naag.org/find-my-ag.
For calls from numbers that appear to be spoofed or from overseas, the Do Not Call complaint process is less directly useful since these callers are outside the registry's jurisdiction. For these calls, the most effective response is using your carrier's spam reporting feature (report the number through your carrier's app or by forwarding to 7726), blocking the number on your phone, and reporting to the FTC for intelligence gathering purposes even if direct enforcement is unlikely. Installing a third-party call blocker (Hiya, Nomorobo, RoboKiller) that uses crowdsourced reporting and behavioral analytics to identify scam calls provides more reliable protection against registry-ignoring scammers than the registry itself can offer.
