Hang up after one sentence if a stranger is selling something or pushing a scare story. "Please put this number on your company's internal do-not-call list. Do not call again." Then end the call.
Will arguing statutes with them change the next call? You can't know from one conversation whether they broke a law. A scammer does not become safe because you quoted a rule.
Hang up when the unexpected call is about money, a delivery, a government agency, or a security alert. Use your statement, official app, or official website.
Use a phone spam call script sparingly
Use a script when the person on the line actually names a real business you might later want to report. Keep the whole call very short.
If it is an identified sales caller
"Please add this number to your company's internal do-not-call list. Do not call this number again. What is your company name?"
Jot the company name if you want it for a later report, then hang up. Skip the extra argument about whether they already had your number on some other internal list, because that detour almost never goes anywhere useful. You'll just stay on the phone.
Don't give them your date of birth, account number, password, or a one-time security code.
If the caller claims to be your bank, insurer, phone company, or a government office
The number on your card, bill, account app, or the organization's official site is the one to use. Never use the callback number they recited.
"I will contact the organization through a number I know is correct. Goodbye."
If a robocall asks you to press a key
You don't need a script. Hang up.
Don't tap any menu key on a suspicious recording, even when the voice says that one press will take you off a list. Don't treat that prompt as proof.
If the caller will not say who they are
"I do not provide information on unsolicited calls. Goodbye."
Caller ID can be faked. A familiar area code proves nothing.
What the National Do Not Call Registry does, and does not do
The National Do Not Call Registry can reduce certain telemarketing calls. It doesn't block every unwanted call, identify scammers, or prove that any one caller broke a law.
Political organizations, charities, survey firms, debt collectors, and purely informational callers are not handled the same way as sales telemarketers. A seller may claim permission or a prior relationship. Those details matter before you accuse a caller of a specific violation.
The FTC's National Do Not Call Registry FAQs explain how to register and report calls. For online registration, the FTC says to open the confirmation email and use its link within 72 hours.
You can register up to three numbers at once.
Thing is, your registration doesn't authenticate callers. Treat an unexpected sales call with caution.
Which rule or process is most relevant?
Rules can overlap. The first issue still changes with the call.
| Type of call | Main consumer protection starting point | Do not assume |
|---|---|---|
| Sales or marketing call | National Do Not Call Registry and the Telemarketing Sales Rule | Every call to a registered number is automatically illegal |
| Automated or prerecorded call or text | FCC rules and the TCPA framework, including the call's purpose and any consent | A spam label or suspicious-looking number proves a violation |
| Debt collection call | Debt collection rules and validation information requirements | The Do Not Call Registry is the main test |
| Fraud impersonating a company or agency | Independent identity checks, account protection, and fraud reporting | Calling the displayed number will verify the caller |
The FTC's Telemarketing Sales Rule materials show why telemarketing has its own requirements. These are general U.S. consumer steps, not a finding that a particular caller violated the law.
A real company's name can show up on a spoofed display, and a criminal can say that same name out loud, which is why the test that actually matters is whether you can reach the organization through a number or app you found yourself rather than whether the voice sounds polished or the area code looks local.
Save the details that make a report useful
Save evidence before you block the number, if your phone allows it. Facts help more than a long story about the argument.
- The displayed number, date, time, time zone, and whether the call was live or prerecorded
- Screenshots of the call log, voicemail, message, or caller ID label
- The company name claimed, the product or account mentioned, and any callback number given
- Whether you had previously done business with the company or gave it permission to contact you
Don't call a suspicious number back just to collect more details. Save a voicemail instead.
Recording a live call is optional, and state consent rules can differ, so check the rules that apply where you are before you record. To be honest, the call log beats a comeback.
Block and label future calls
Use your phone's blocking tools first. Carriers sometimes add call filtering, and third-party apps can screen calls before they reach you.
The FTC's guidance on blocking unwanted calls explains that blocking tools can stop many scam calls and illegal robocalls, while call-labeling tools may show warnings such as spam or scam likely. A label is a warning, not proof.
Blocking won't always end the problem, because callers can change or spoof numbers. You'll still get fewer interruptions. You also avoid re-engaging the same displayed number.
Put the complaint in the right place
Reporting creates a record. It doesn't usually fix one call in real time.
| Where to report | Use it for | What to expect |
|---|---|---|
| FTC National Do Not Call guidance | Unwanted telemarketing and possible Do Not Call concerns | The FTC analyzes complaint data and calling patterns to help identify illegal callers |
| FCC unwanted calls and texts instructions | Unwanted calls, robocalls, texts, and caller ID spoofing | The FCC says it does not resolve individual unwanted-call complaints, but reports can support policy and enforcement work |
| CFPB debt collection resources | Problems with a debt collector or a debt collection notice | The CFPB may forward your complaint to the company and generally works to get a response within 15 days |
On the FCC form, choose "unwanted calls/texts." Its instructions distinguish general unwanted calls or messages from reports that your own number is being spoofed.
Keep the evidence, file the issue that matches the call, and watch the account or company the caller claimed to represent. Turns out, no single complaint form blocks a call instantly.
Use a different script for a debt collector
Don't use a generic spam script if the caller may be a real debt collector. The account might be legitimate. You still shouldn't confirm personal or financial details until you verify who is contacting you.
The CFPB says that a debt collector generally must provide validation information in the first communication or within five days. That information includes the creditor's name, the amount claimed, and how to dispute the debt.
Use this instead:
"Please send the validation information in writing. I will review it before discussing this account."
Keep any notice you receive. Follow the dispute instructions and deadline stated in that notice. Contact the alleged creditor through a trusted number if you need to verify the account.
When the next unexpected call comes in, hang up if you can't tell who it is, then save a screenshot and block the number. Don't stay on the line.
If the caller claims a real account, find the official contact information yourself. For repeated telemarketing, use the FTC reporting route; for unwanted calls or texts, use the FCC process.
