How to Stop Spam Calls and Texts for Good
The short version
No single switch stops spam calls and texts, because the calls come from two different worlds: legitimate marketers who must obey opt-outs, and criminals who ignore every rule. The plan that works is layered. Register on the National Do Not Call Registry (free, never expires) to shut down lawful telemarketing. Turn on your carrier's blocking and spam labeling to filter the illegal traffic. Use the FCC's opt-out words to force real businesses to stop. Report what gets through, because those reports feed the blocklists. Then cut the supply by removing your number from the data brokers that publish it.
Where spam callers and texters get your number
Almost nobody dials your number at random. It gets published, sold, and traded. People-search sites list it next to your name, age, addresses, and relatives, where anyone can copy it. Lead-generation and quote forms hand it to marketing partners. Breached databases put it on resale markets. Public records and old directories fill in the rest.
That matters because every fix below falls into one of two buckets: filtering calls after they reach you, or shrinking the number of lists your phone number sits on. Most advice only covers the first bucket, which is why people feel like they are bailing out a boat with a hole in it.
Why blocking numbers one at a time never works
Blocking is worth doing, but the numbers work against it. Scammers fake, or spoof, the number on your caller ID, so the number you just blocked was probably never theirs. The FTC also warns about neighbor spoofing, where callers match your area code and often the first six digits of your number so the call looks local.
The FTC notes that a spoofed name and number frequently belong to a real, uninvolved person. Blocking still helps against persistent legitimate callers and against the same scam number being reused for a day or two. It just cannot be your whole strategy.
Step 1: Get on the National Do Not Call Registry
This is the free, five-minute baseline. Register at DoNotCall.gov or by calling 1-888-382-1222 from the phone you want to register. Cell phones are eligible. If you register online you have to click a confirmation link within 72 hours. According to the FTC, registration never expires.
Be clear about what it does. The FTC describes the Registry as a list that tells registered telemarketers what numbers not to call - it does not block calls. Your number shows up on the list the next day, but telemarketers get up to 31 days to stop calling you. Scammers making illegal calls ignore it entirely.
Some calls stay legal even after you register, as long as they do not include a sales pitch: political calls, charitable calls, debt collection, purely informational calls, and surveys. Companies you have recently done business with may also call you. If you tell them to stop, they have to - write down the date you asked.
The penalties are real for the callers who can be found. The FTC says companies that illegally call registered numbers or place an illegal robocall can currently be fined up to $50,120 per call, and that telemarketers who made illegal calls have paid more than $290 million in judgments.
Step 2: Turn on call blocking and labeling
Call blocking stops suspected junk before it rings; call labeling lets it through but tags it as "spam" or "scam likely" so you can decide. The FTC recommends both, and points out that you probably have three sources of it already: your phone's built-in settings, your wireless carrier, and third-party apps.
On a cell phone, start with the free layer. Most phones can silence unknown callers, block specific numbers, and filter messages from senders who are not in your contacts. Then check what your carrier offers - many include spam filtering at no cost. The FCC keeps a Call Blocking Resources page with company-specific instructions, and the wireless industry site ctia.org lists blocking apps by platform.
On a traditional landline, the equivalent is a call-blocking device: a small box that uses a database of known scam numbers, or your own list, and can send calls to voicemail or make callers press a key to get through. If your home phone runs over the internet (VoIP), use an internet-based blocking service instead.
One honest caveat from the FTC: blocking services sometimes block calls you wanted. If you are expecting a call from a clinic, a school, or a delivery driver, check your blocked and spam folders.
Step 3: Use the words that legally force a sender to stop
For legitimate businesses, you have more leverage than most people realize. FCC rules that took effect on April 11, 2025 say you can revoke consent to robocalls and robotexts using any reasonable method, and that the caller must then stop. There are, in the Commission's own words, no magic words you have to say.
Replying to a text with "stop," "quit," "end," "revoke," "opt out," "cancel," or "unsubscribe" counts automatically as a valid revocation. Other wording still counts if a reasonable person would understand it as a request to stop. You can reply in the language the message was sent in. Pressing the opt-out key on an automated call, or using the opt-out website or phone number the caller gave you, works the same way.
Two details worth knowing. First, once you opt out, callers must honor the request within a reasonable time not to exceed 10 business days. Second, a text sender is allowed to send exactly one message confirming that you opted out, and nothing after that.
There is a catch that most articles miss. The rule that a single opt-out must cover all of that caller's unrelated future robocalls and texts has been waived. In an order adopted on January 6, 2026, the FCC extended that waiver until January 31, 2027. Practically: telling a bank's fraud-alert line to stop may not stop its marketing texts. Opt out on every channel that contacts you, and keep dated notes.
Step 4: Report the ones that get through
Reporting feels like shouting into a void, but the reports are wired directly into the filtering you rely on. The FTC says it takes the phone numbers consumers report and releases them each business day to carriers and industry partners building call-blocking and call-labeling tools.
For a spam text, the FTC gives three options: copy the message and forward it to 7726 (which spells SPAM), which helps your carrier spot and block similar messages; report it as junk inside your messaging app; and report it to the FTC at ReportFraud.ftc.gov.
For a call, use DoNotCall.gov if you did not lose money, or ReportFraud.ftc.gov if you did or you have information about who called. Include the number that received the call, the number shown on your caller ID even if you suspect it is fake, any callback number you were given, and the date and time.
Step 5: Cut the supply at the data brokers
This is the step that changes your baseline instead of your filters. People-search sites publish your phone number alongside your name, age, current and past addresses, and relatives, which is exactly the package a lead broker or a social engineer wants. Every major one has a free opt-out.
The catch is maintenance: brokers continuously re-ingest public records and buy data from each other, so removed listings commonly reappear within three to six months. We keep free, dated opt-out guides for the biggest brokers, including awkward ones like Whitepages, whose opt-out requires phone verification. Our full walkthrough is in how to remove yourself from data brokers.
If you want to see where you stand before you start, RedactZero's free exposure scan lists the brokers likely to have you and checks your email against known breaches, and nothing you type is stored. It is also worth reading who buys your location data, since the same broker pipelines carry both.
The lead-generator loophole that is still open
In December 2023 the FCC adopted a one-to-one consent rule to close what it called the lead generator loophole: the practice where one checkbox on a comparison-shopping site is treated as consent for dozens of sellers to call and text you. The rule was set to take effect on January 27, 2025.
It never did. On January 24, 2025, the Eleventh Circuit vacated it in Insurance Marketing Coalition Ltd. v. FCC, holding that the new consent restrictions conflicted with the ordinary statutory meaning of "prior express consent." The loophole the rule targeted stayed open.
So treat every insurance, loan, solar, or warranty quote form as a phone-number giveaway. Read what the consent line actually says, look for the words "marketing partners," and use a secondary number when a form demands one for something you do not need.

What the complaint numbers actually show
Unwanted calls got worse in the most recent year of federal data, but they are still well below the 2021 peak. The FTC logged about 2.6 million Do Not Call complaints in fiscal year 2025, up from roughly 2.1 million a year earlier, while active registrations reached about 258.5 million as of September 30, 2025.
| Fiscal year | Robocall complaints | Live-caller complaints | Total |
|---|---|---|---|
| 2021 | 3,427,949 | 1,100,066 | 5,008,987 |
| 2022 | 1,844,210 | 889,891 | 3,054,237 |
| 2023 | 1,157,748 | 730,159 | 2,118,808 |
| 2024 | 1,099,229 | 764,138 | 2,085,410 |
| 2025 | 1,601,611 | 802,144 | 2,618,077 |
Source: FTC, National Do Not Call Registry Data Book, Fiscal Year 2025. Totals also include complaints where the call type was not reported (214,322 in FY 2025).
Robocalls, not live callers, drive the totals and drove the FY 2025 increase, and the most-reported topics stayed consistent: reducing debt, imposters, and medical and prescription offers.
For perspective, phones are not where most fraud money is lost. FTC data released in April 2026 found social media was the costliest contact method in 2025, with $2.1 billion in reported losses, and that phone calls ranked first only for people aged 80 and over. Spam calls are a nuisance and a targeting channel for most of us, and a genuine financial threat to older relatives.
What not to do, and a plan you will keep
Do not press a number to be "removed from our list" on an illegal robocall, and do not call back. The FTC is explicit that pressing a key can lead to more robocalls, because it proves a human answered. Do not reply to a text from a sender you have no relationship with, for the same reason. Never give personal or financial details to an inbound caller.
The realistic version of all this takes about an hour up front: register on the Registry, switch on your phone and carrier filters, and opt out of the top people-search sites. After that it is roughly ten minutes a quarter to re-check the brokers and re-file the listings that came back.
You will not get to zero. Between spoofing and offshore call centers, some volume is simply out of your control. What you can control is how many lists your number sits on and how quickly the legal callers are forced to drop you.

Frequently asked questions
Does the National Do Not Call Registry actually work?
Partly. The FTC describes the Registry as a list that tells registered telemarketers which numbers not to call - it does not block anything. It reduces sales calls from companies that follow the law, and it makes the remaining calls easier to spot as scams, but it does not stop illegal callers.
Should I reply STOP to a spam text?
Reply STOP only to senders you actually signed up with. Under FCC rules, words like stop, quit, end, revoke, opt out, cancel, and unsubscribe are automatically a valid revocation of consent. For a text from a stranger or an obvious scam, do not reply at all - forward it to 7726 instead.
How long does a company have to stop calling after I opt out?
Under the FCC's TCPA consent rules, callers must honor a do-not-call or revocation request within a reasonable time, not to exceed 10 business days after they receive it. Compliance with that timeframe has been required since April 11, 2025.
Why do I get spam calls from my own area code?
That is neighbor spoofing. The FTC says scammers fake caller ID and often match your area code and the first six digits of your number so the call looks local. The displayed number is usually not theirs, which is why blocking numbers one at a time rarely helps.
Does registering my cell phone on the Do Not Call Registry cost anything or expire?
No on both counts. Registration is free at DoNotCall.gov or 1-888-382-1222, cell phones are eligible, and the FTC says registration never expires. Your number is only removed if it is disconnected and reassigned, or if you ask for it to be removed.
Where do spam callers get my phone number?
Mostly from places you never chose. People-search sites publish phone numbers next to your name, age, addresses, and relatives. Lead-generation and quote forms pass your number to marketing partners. Breached databases put it on resale markets. Public records and directories fill the gaps.
Is it worth paying for a call-blocking app?
Often yes, but check the free options first. Your carrier and your phone's built-in settings already offer blocking and spam labeling. The FTC notes that call-blocking services can also block calls you wanted, and that some apps read your contacts - so read the privacy policy before installing one.
Will removing myself from data brokers stop spam calls completely?
No, but it shrinks the supply. Opting out removes your number from the listings that feed lead lists, and it has to be repeated because brokers re-ingest public records and commonly relist people within three to six months. Combine it with blocking, the Registry, and reporting.
