To remove your phone number from spam lists, start by registering it free on the National Do Not Call Registry at donotcall.gov, then layer on your phone’s built-in filters, carrier blocking, STOP replies to unwanted texts, and opt-out requests to the data brokers selling your number. No single step stops every call, but together they cut spam down to something manageable.
Register on the National Do Not Call Registry
The Do Not Call Registry is the federal list that blocks most commercial telemarketers from contacting you. Sign up at donotcall.gov or call 1-888-382-1222 from the phone you want protected. Online registrations require you to click a confirmation link in your email within 72 hours. Phone registrations have to come from the number itself. Registration is free and never expires.1Federal Trade Commission. National Do Not Call Registry FAQs
After 31 days on the list, telemarketers are legally required to stop calling. The Telemarketing Sales Rule forces sellers to check an updated version of the registry at least every 31 days and scrub listed numbers from their campaigns.2eCFR. 16 CFR 310.4 – Abusive Telemarketing Acts or Practices Companies that ignore the rule face civil penalties per violation.3Federal Register. Adjustments to Civil Penalty Amounts
What the Registry Won’t Stop
The list only covers commercial sales calls. Charities, political campaigns, survey firms, and debt collectors can still reach you. Scammers don’t check the registry at all, which is why the rest of the steps below matter.
There’s also a business relationship exception. A company you’ve bought from can keep calling for 18 months after your last purchase, delivery, or payment. If you only made an inquiry or filled out an application, that company gets a three-month window. Telling them directly to stop calling ends the exception right away.4Federal Trade Commission.

Reply STOP to Spam Texts (When Safe)
The Telephone Consumer Protection Act, the same law behind the Do Not Call Registry, requires companies to get your consent before sending automated texts and lets you revoke that consent whenever you want.5Office of the Law Revision Counsel. 47 USC 227 – Restrictions on Use of Telephone Equipment
FCC rules list the words that count as a valid opt-out: STOP, QUIT, END, REVOKE, OPT OUT, CANCEL, or UNSUBSCRIBE. Reply with any of them and the company has ten business days to stop. Companies cannot require one specific opt-out method. A voicemail, email, or any other reasonable revocation has to be honored too.6Federal Communications Commission. FCC 24-24A1 – Consent Revocation Rules
One caution. Only reply to senders you recognize, especially those using five- or six-digit short codes. If a text comes from an ordinary ten-digit number and looks like a scam, replying STOP just confirms your number is active and invites more. Block and report those instead.
Turn On Your Phone’s Built-In Filters
Your phone can catch a lot of what the registry misses. On iPhone, “Silence Unknown Callers” in the phone settings routes any number not in your contacts straight to voicemail. Android’s dialer has a similar “Spam Protection” toggle that flags or blocks suspicious numbers. Both work well, though a legitimate unknown caller can occasionally get caught, so checking voicemail matters.
Wireless carriers add a second layer before calls reach your phone. Most major carriers offer free or low-cost apps that label incoming calls “Scam Likely” or “Potential Spam” and let you block categories like telemarketing, surveys, and suspected fraud. These tools use STIR/SHAKEN, a caller ID authentication system the FCC required carriers to implement, which helps verify that a call actually comes from the number displayed.7Federal Communications Commission. Combating Spoofed Robocalls with Caller ID Authentication
STIR/SHAKEN has limits worth knowing. A verified call only means the number wasn’t spoofed. It doesn’t mean the caller is trustworthy. The FCC has acknowledged that consumers sometimes read a verification checkmark as a guarantee against scams, which isn’t what it means.8Federal Register.

Remove Your Number from Data Brokers
Registering on the Do Not Call list doesn’t touch the data brokers who compile and sell your contact information. Companies like Spokeo, BeenVerified, and WhitePages pull from public records, commercial transactions, and social media, then sell the results in bulk. Telemarketers and scammers buy those lists to build their call targets. Cutting the supply upstream reduces the volume you get over time.
The removal process is tedious but simple. Search yourself on each broker’s site, find your listing, and submit an opt-out through their privacy portal. Most brokers ask for email verification before processing the request. Responses usually arrive within about 45 days, sometimes faster. The catch is that a broker can re-add your information later from a different source, so rechecking every few months helps.
Paid removal services automate this across dozens or hundreds of brokers at once. They generally cost between $20 and $130 a year. Whether that’s worth it depends on how exposed your information is and how much time you want to spend on manual requests. For most people, opting out of the five or six largest brokers covers most of the exposure.
Report Violators and Consider Suing
A complaint won’t stop the call you just got, but it feeds enforcement databases the agencies use to build cases. File FCC complaints for robocalls, spoofed numbers, and unwanted texts at consumercomplaints.fcc.gov.9Federal Communications Commission. FCC Complaints Report Do Not Call Registry violations at donotcall.gov once your number has been listed 31 days or more.10Federal Trade Commission. National Do Not Call Registry Forward spam texts to 7726 (which spells SPAM); carriers use those reports to block similar messages.11Federal Trade Commission. How to Recognize and Report Spam Text Messages
You can also sue. The TCPA gives you a private right of action in state court, worth $500 per illegal call or text, or $1,500 per violation if the court finds the conduct was willful.5Office of the Law Revision Counsel. 47 USC 227 – Restrictions on Use of Telephone Equipment Ten texts from the same company can add up to $5,000 to $15,000. Small claims court handles most of these cases with modest filing fees and no lawyer required. Save the texts and call logs, note dates and times, and screenshot every opt-out you sent. A company that kept texting after you replied STOP has handed you strong evidence of a willful violation. The hardest part is usually identifying who’s actually behind the calls, since spammers routinely hide behind shell entities and spoofed numbers.
