For U.S. consumers, the safest sequence is simple: end the call, preserve the details, report it through the route that fits, and then block the number or calling pattern. If you shared account information or sent money, contact the bank or payment service first. Caller ID can be spoofed, so the number on your screen may not identify the caller.

The National Do Not Call Registry, the Federal Trade Commission (FTC), and the Federal Communications Commission (FCC) have different roles. The registry can reduce covered telemarketing calls, the FTC collects reports about fraud and illegal telemarketing, and the FCC accepts complaints about unwanted calls and related communications practices.

Quick checklist for reporting a spam call

1. Hang up. Don't call back or press a number in a suspicious call or voicemail.
2. If you shared information or sent money, contact the affected bank, card issuer, or payment service immediately using a trusted number.
3. Save the voicemail, screenshots, and call details before deleting or blocking anything.
4. Register your number at the National Do Not Call Registry if you haven't already.
5. Use the matching report route:
   • Report unwanted sales calls and robocalls through DoNotCall.gov.
   • Report fraud, an imposter call, or an attempted scam at ReportFraud.ftc.gov.
   • Submit an unwanted-call complaint through the FCC Consumer Complaints Center.
6. Turn on your carrier's call-labeling and blocking tools, or use your phone's built-in controls.
7. Keep a dated log if the calls continue.
8. Consider legal advice only after preserving the records needed to evaluate a possible claim.

Identify what kind of call you received

Not every unwanted call is covered by the same rule. Identifying the category helps you choose the right report and avoid guessing about the caller.

A sales pitch delivered by an automated voice is treated differently from an informational message, healthcare reminder, or call for which you gave permission. The call's purpose, your consent, the number called, the technology used, and the caller's identity can all affect whether it violated a rule.

Register your number on the National Do Not Call Registry

Registration is free:

1. Open the National Do Not Call Registry.
2. Enter up to three phone numbers at a time and an email address.
3. Open the confirmation email for each number.
4. Click each confirmation link within 72 hours.
5. Save the confirmation email and registration date.

Telemarketers generally have up to 31 days to update their calling lists. A sales call after that period may support a complaint, but the timing alone doesn't prove a violation. Consent and exceptions can still matter.

The registry doesn't technically block calls. It tells covered telemarketers not to make certain sales calls to your number. Scammers may ignore it, and the registry generally doesn't cover political calls, charitable solicitations, surveys, debt collection, or purely informational calls in the same way. Some calls from a company with an existing relationship may also be treated differently.

If a legitimate company keeps making marketing calls, ask it to place your number on its internal do-not-call list. Keep a copy of the request. Don't use a callback number, link, or email address supplied by a suspicious caller to make that request.

Save evidence before blocking the number

A caller can spoof the number shown on your screen. Record what the caller said, not just the displayed number.

Create a log with details such as these:

Save screenshots of the call log, voicemail files, text messages, and related emails. Keep original files unedited. If the calls appear connected, use consistent file names and create a separate entry for every call.

Be cautious about recording a live call yourself. U.S. state laws differ on whether one or all participants must consent, and the caller may be in another state. A written log and the voicemail you received avoid the extra legal question created by making a new recording. If you plan to record calls for a possible legal claim, check the law that applies or consult a qualified attorney first.

Report the call to the FTC

Use the FTC route that matches the conduct:

• Report an unwanted sales call or robocall through the reporting tools at DoNotCall.gov.
• Report a scam, imposter call, or attempted fraud at ReportFraud.ftc.gov.
• For background on legal and illegal robocalls, review the FTC's Robocalls guidance.

Include the number that received the call, the displayed caller ID, the date and time, the caller's claimed identity, and the substance of the message. If the caller gave you a different callback number, list that separately. Say when a detail is uncertain rather than guessing.

The FTC analyzes complaint data and calling patterns to identify illegal callers. The FTC also says that phone numbers reported by consumers are released to the public each business day. These reports can help identify campaigns and support investigations and industry efforts to block abusive calls.

An FTC report isn't a private lawsuit, a request for a refund, or a promise that an investigator will contact you. It also won't guarantee that the next call will stop. Accurate reports remain useful when multiple consumers describe the same campaign.

File an unwanted-call complaint with the FCC

The FCC accepts complaints about unwanted calls and texts through its Consumer Complaints Center. Select the unwanted-calls category and provide:

• the number where you received the call
• the number shown on caller ID
• any callback number or number mentioned in the voicemail
• whether the call was live, prerecorded, or generated by an automated system
• the date, time, and frequency of the calls
• whether you gave consent or asked the caller to stop
• the name the caller used and what the caller wanted

The FTC and FCC serve different purposes. The FTC focuses heavily on fraud, telemarketing, and patterns of illegal calls. The FCC handles communications rules and complaints involving providers and calling practices. Filing with both can make sense when a call is fraudulent and also an unwanted robocall.

The FCC's complaint FAQ describes its informal complaint process. If the FCC serves the complaint on a provider, that provider is required to respond in writing within 30 days of receiving it. The process doesn't guarantee a response from the scammer, compensation, or a particular enforcement action against the caller.

Block calls after preserving your records

Blocking is a prevention step, not a replacement for reporting. Start with tools provided by your phone and carrier:

• Turn on your carrier's spam identification or call-labeling feature.
• Use the carrier's blocking or suspected-spam controls.
• Enable your phone's option to silence or screen unknown callers if you can still receive expected calls another way.
• Block individual numbers after saving the evidence.
• Review the FCC's call-blocking resources for provider and device options.

Blocking one number may not stop a campaign if the caller spoofs different numbers. Paid apps may offer additional screening, but compare their current pricing, permissions, privacy policy, and cancellation terms before subscribing. A filter that blocks every unknown caller can also suppress calls from a doctor's office, delivery driver, school, or employer.

Never install an app, share your screen, or give remote access because a caller says it will remove your number from a list.

Ask a legitimate company to stop marketing calls

If you can verify that the caller is a real business, send a written request through its official website, customer account, or statement contact. Don't use the suspicious call itself to make the request.

You can write:

Please place [phone number] on your internal do-not-call list. I am withdrawing permission for marketing calls to this number. Please confirm the request and identify any account or department handling it.

Save the message, the date sent, and the company's reply. If calls continue, add each one to your log. A request to stop marketing calls doesn't necessarily cancel a service, loan, appointment, or other account relationship. State clearly that you are withdrawing marketing permission if that is what you mean.

Act quickly if the call caused financial or identity harm

If you gave a caller a password, one-time verification code, bank detail, card number, or Social Security number, take these steps before focusing on the complaint:

1. Call your bank, card issuer, or payment provider using the number on a statement, card, or official app.
2. Ask whether the transaction can be stopped, reversed, or flagged. Recovery isn't guaranteed, but speed matters.
3. Change exposed passwords and don't reuse them on other accounts.
4. Review account activity and enable available security alerts.
5. Report the fraud to the FTC and keep the confirmation for your records.

If you disclosed a Social Security number or other identity information, record exactly what you shared and include it in the fraud report. Don't provide additional information to someone who calls claiming to help you recover the money.

If a caller threatens immediate physical harm or you face an immediate safety emergency, contact emergency services. Don't try to confront or trace the caller yourself.

For an identifiable business, a complaint to your state attorney general or consumer-protection office may provide another enforcement route. Use the official state website and submit the same evidence package. An agency complaint doesn't automatically create a private claim or guarantee a refund.

Could a spam call support a TCPA claim?

A complaint and a lawsuit are separate processes. The Telephone Consumer Protection Act (TCPA) may apply to some telemarketing calls, calls using an autodialer, prerecorded or artificial-voice calls, and calls to numbers on the Do Not Call Registry. The applicable rule depends on the call's purpose, the technology used, the number called, consent, and any exception.

TCPA damages are commonly described as $500 per qualifying violation, with up to $1,500 per violation when a court finds that the conduct was willful or knowing. Those amounts aren't automatic. Filing an FTC or FCC complaint doesn't make the agencies pay them, and multiplying the number of calls by a damages figure isn't enough to establish a claim.

Before discussing a possible claim with a licensed attorney, organize:

• a call-by-call log
• original voicemails and screenshots
• your Do Not Call registration confirmation
• consent forms or account records
• written requests to stop
• the caller's company names and payment instructions
• evidence showing whether the calls were sales calls, scams, or informational messages

Spoofing can make it difficult to identify the business responsible. Don't assume the owner of the caller ID number placed the call, and don't promise yourself a particular recovery amount. A qualified attorney can assess whether the facts support a TCPA case, a state-law claim, or neither.

Common questions

Why am I still getting calls after registering?

The registry needs time to reach telemarketing lists, and scammers may ignore it. Some types of calls are outside the registry's coverage. Use blocking tools, report the pattern, and preserve new evidence instead of repeatedly registering the same number.

Should I report a call if I don't know whether it's illegal?

You can report a call that appears fraudulent, deceptive, or persistently unwanted. Describe what you know and label uncertain details as uncertain. Don't guess the caller's identity or claim that a call was automated if you can't tell.

Can the FCC or FTC stop the caller immediately?

Usually not. Reports help agencies analyze patterns and support enforcement. Carrier and phone tools are more likely to reduce calls reaching your device right away, although no filter catches every spoofed number.

Does filing a complaint get me money?

No. FTC and FCC complaints are enforcement and data-gathering routes, not automatic compensation claims. Payment recovery requires a separate dispute process, and a private lawsuit requires facts that meet the applicable law.

For the next suspicious call, save the voicemail and screenshot first, add the date, time, displayed number, and claimed identity to your log, and then file the report that matches the conduct.
