In the United States, report an unwanted call with no reported financial loss through DoNotCall.gov. Use ReportFraud.ftc.gov if you lost money or have information about the scammer or company. File a Federal Communications Commission (FCC) complaint for unwanted calls, robocalls, caller-ID spoofing, or spoofing of your own number. Separately, ask your phone carrier what blocking, labeling and screening options it offers for your plan and device.
These reports give regulators and carriers data for analysis and possible enforcement; they are not a guaranteed way to identify a caller, stop calls immediately or receive an individual response.

Choose the right reporting route
The best destination depends on what happened and what result you want. The FTC collects consumer reports and shares phone numbers with telecommunications carriers and other industry partners working on call blocking and labeling. The FCC accepts telecom complaints and uses them to inform policy and possible enforcement. Your carrier handles practical blocking or screening on your line.

| Situation | Where to report | What the route does | What it does not promise |
|---|---|---|---|
| Unwanted call, with no reported financial loss | DoNotCall.gov | Records the unwanted-call report for FTC analysis and industry sharing. | It does not guarantee an individual reply or immediate stoppage. |
| You lost money in a phone scam, or know something about the scammer or company | ReportFraud.ftc.gov | Creates a fraud report with details about the loss, company or scammer. | It does not guarantee recovery of money or a personal investigation response. |
| Unwanted calls, robocalls, or caller-ID spoofing | FCC Consumer Complaint Center | Supplies information used for policy decisions and potential enforcement. | The FCC says it does not resolve individual unwanted-call complaints. |
| Your own number is being spoofed, blocked or labeled as potential spam | FCC complaint flow for “my own number is being spoofed” | Places the problem in the FCC’s specific numbering and spoofing category. | It does not establish who made the calls or guarantee that labels will change. |
| Prevent future calls on your line | Your carrier, device or call-screening service | May block, label or screen calls according to your plan and device. | There is no single carrier process or universal feature set. |
This guide covers U.S. federal routes. A carrier’s process and authorities in another country can be different.
#1 Best Overall
- COMPATIBILITY: For traditional analog landline phones and services from providers such as AT&T, Verizon, Frontier Communications, CenturyLink, and Brightspeed. Not compatible with internet-based or digital phone services (VoIP), including Vonage, Ooma, Xfinity Voice, and Quantum Fiber.
- IMPORTANT: The V5000 CPR Call Blocker requires Caller ID service and an analog telephone line. Without Caller ID, incoming numbers cannot be identified or blocked. No mains power required - just plug it into your phone line and use.
- Powerful Blocking, Made Simple: Preloaded with 5,000 verified scam and nuisance numbers, the V5000 starts protecting you right out of the box. And if a new or spoofed number gets through, the large “BLOCK NOW” button makes it easy to instantly block it - up to 1,500 additional numbers at your command.
- Realistic & Reliable Protection: While no device can stop 100% of spam (scammers constantly change numbers), the V5000 gives you the power to shut down repeat offenders quickly and effectively - offering more control than passive filters alone.
- Hassle-Free Design: NO POWER supply needed, NO APP, and NO SUBSCRIPTIONS. The V5000 is easy to install, with a clear screen and loud button click for extra confidence. Designed with seniors in mind, it’s ready to use and simple to maintain. For even stronger protection, you can pair it with your phone provider’s spam filtering service.
Record the call before deleting anything
Collect the details while the call is still visible in your call history or voicemail. The FTC specifically asks for the number that received the call, the number shown on caller ID, any number the caller told you to call back, and the date and time if known.
Capture the receiving number
Write down the phone number that actually received the call. If you manage several lines, note the specific line rather than only the account holder’s number. This lets an agency distinguish your number from the number displayed by the caller.
Save caller-ID information exactly as displayed
Record the caller-ID number and any name or label shown on the screen, even when you suspect it is fake. A spoofed number can still help authorities analyze calling patterns. Describe it as “caller ID showed” rather than claiming that it proves the caller’s identity.

Scammers often display one number but ask you to call a different number. Record that requested number separately. Include it even if you did not call back.
Add the date, time and substance of the call
Include the date and time when available, whether the call was a live conversation or an automated message, and what the caller said or requested. Preserve a voicemail until you have copied the relevant details. Do not embellish an uncertain detail; an accurate “unknown” is more useful than a guess.
Understand why caller ID is not proof
Caller ID can be forged. The FTC says scammers can fake names and numbers, including local-looking numbers and numbers belonging to unrelated people. A familiar area code, a government-looking label or a neighbor’s number does not establish who made the call.
Rank #2
- How it Works: SPAM identified calls are instantly blocked automatically. Preferred Calls Ring through like normal with Caller ID displayed. Your phones connected to the TEL port Won't Ring on Blocked Calls. Create your own Invited or Allowed Family (White List) and block All other callers. Use the Dual Block Buttons to Block a NAME or NUMBER Displayed. Remote Block a Call when Dialing * 2 # through your telephone handset.
- The Patented ProSeries 3 Call Blocker from Digitone is an Easy Installation and is Simple to Use. No need to rush over and tap a red button when the ProSeries has already blocked a known unwanted SPAM, Out of Area, Private, Anonymous, 800 Service, ROBO?, Dashes, "Quotes" or V123+ call. Use Call History to select Any Caller to Block by (Double Tap) Name or Number. Block any NAME like: Unavailable, Unknown, SCAM RISK, City + State, Potential Scam, Wireless Caller. Block ANY call without answering, as they call in with either RED button.
- Feel confident that the ProSeries already Blocks Millions of Known Unwanted Numbers and Fake Names. No need to change your existing phones or service. Works with Any Analog Corded, Cordless Phone or Fax System on any telephone service. Large Back-Lighted Display. Got questions? Call the number on the front screen of the ProSeries 3.
- Works with all USA phone companies: AT&T, Cox, Spectrum, CenturyLink, Cable Modems, DSL, FIOS, or Digital Services from VoIP Telcos like [V] from Verizon, Ooma Telo, Ooma Basic, Vonage, Magic Jack etc. Also, works in Mexico, Canada, Brazil, European Union (ETSI), Australia, Singapore and others with North American standardized phone lines.
- Allow any blocked caller to ring through like normal with the Green Invite Button. Double Tap the Green Button to add VIP callers shown in Call History. Note: Caller ID Name and Number Service from your phone company is required for this model to work automatically.
When a form asks for the number, enter what appeared on your screen and identify it as caller ID. If the caller supplied a separate callback number, enter that in the field for the number they told you to use. This preserves both pieces of evidence without accusing the owner of the displayed number.
Report an unwanted call to the FTC
Use DoNotCall.gov when there was no reported loss
For an unwanted call without a reported financial loss, submit the streamlined form at DoNotCall.gov. Use the call details you recorded: receiving number, caller-ID number or label, callback number and date or time when known.
This route is appropriate for nuisance calls, robocalls and suspected scam calls when you are not reporting that you paid money. The FTC receives millions of reports each year and analyzes them rather than responding individually to every consumer.
Use ReportFraud.ftc.gov after a loss or when you have scammer information
If you lost money in a phone scam, or have information about the company or scammer, use ReportFraud.ftc.gov. Include the amount and circumstances of the loss as accurately as possible, along with the caller-ID and callback numbers and any identifying information the caller provided.
Choose this route even if the displayed caller ID appears to belong to someone else. Explain that the number was shown on caller ID and may have been spoofed. Do not present it as confirmed ownership.
Report legitimate sales calls through the Do Not Call process
The National Do Not Call Registry is aimed at legitimate companies that follow telemarketing rules; it is not a defense against scammers who ignore the law. If your number is not registered, registration can take up to 31 days to take effect. A registration does not technically block a call on your handset.
Rank #3
- This is the latest version Telephone Call Blocker with hidden or unavailable call numbers can be blocked. And there is no fees to use it; Please keep the manual for future use.
- Block up to 4000 individual phone numbers, including incoming and outgoing calls , prefixes and up to 10 digit area codes.
- One-touch to Block: Locate a number and then press Block to add it to the blacklist.Better set the call blocker in series ( one end of it connected to your phone and another end to the PSTN telephone line); Though it can also be set up parallel, but not compatible with some phone systems.
- Permanent storage of the numbers in the blacklist even power is off or telephone line is plugged out.
- Battery free: It is line powered, no need battery. And it works with almost all single line telephones. If you find some numbers are blocked but you never mean to, then press Block and check your blacklist, then delete those numbers which like area codes or prefix numbers.
Use the FTC’s Do Not Call reporting route for an unwanted legitimate sales call after checking your registration status. The Registry is a compliance signal to legitimate telemarketers, not a call-filtering technology.
File an FCC complaint for unwanted calls, robocalls or spoofing
Report the call type that fits
The FCC complaint center accepts complaints about unwanted calls and robocalls, including caller-ID spoofing. Select the issue that most closely matches what happened and provide the evidence you recorded. If your own number is being spoofed, blocked or labeled as potential spam, use the separate issue path labeled “my own number is being spoofed.”
Handle an international-format number
Some caller-ID numbers do not match the form’s usual number format. FCC guidance says to put an international-format number in the “Additional Information” field. Form labels can change, so read the current instructions on the complaint page as you submit.
Recommended Free Tools
Set the correct outcome expectation
The FCC’s consumer guidance states:
“We do not resolve individual unwanted call or text complaints, but your complaint provides valuable information that we use to inform policy decisions and as the basis of potential enforcement actions against those violating our rules.”
That means an FCC complaint is worthwhile as evidence for patterns and enforcement, but it is not a case-tracking service that promises a call back, a caller identity or a direct fix for your line.
Ask your carrier for blocking and screening
Agency reporting and carrier controls serve different purposes. Contact your carrier through the support channel associated with your plan and ask which call-blocking, call-labeling and call-screening features are available for your particular device and account.
Rank #4

Questions to ask support
- Which incoming-call blocking options are included with my current plan?
- Can the carrier label suspected spam or send it to a screening process?
- Is the feature controlled in an account portal, a carrier application, a handset setting or by support staff?
- Does enabling it block all unknown callers or allow exceptions?
- How can I report a number that was incorrectly labeled?
There is no universal carrier short code, application or escalation path established for every provider. Do not assume that a procedure used by one carrier works on another. Ask support to document the feature name, activation method and any limits that apply to your plan.
Separate blocking from reporting
Blocking can reduce calls on your device, but it does not send a regulatory complaint. Conversely, an FTC or FCC report does not automatically activate a block on your line. You may need to do both: submit the report so the number contributes to broader analysis, then enable the carrier or device control that fits your needs.
Reporting, registration and blocking are different actions
| Action | Primary purpose | Who controls it | Typical timing or limitation |
|---|---|---|---|
| Report a call | Give agencies factual information for analysis, policy and possible enforcement. | FTC or FCC | No guaranteed individual response or immediate stop. |
| Register a number on the National Do Not Call Registry | Tell legitimate telemarketers not to call a listed number. | Consumer through the FTC’s Registry system | FTC guidance says registration may take up to 31 days; scammers may ignore it. |
| Block or screen a call | Reduce or filter calls reaching your phone. | Carrier, handset or call-screening service | Availability and controls vary by carrier, plan and device. |
The Registry is not a technical call blocker. A number can be registered and still receive illegal scam calls, while a blocked number may never be reported to an agency unless you submit a separate complaint.
A complete reporting workflow
- Stop and document. Before clearing call history or voicemail, record the receiving number, caller-ID number or label, any callback number, date and time, and the caller’s request.
- Classify the event. Decide whether it was an unwanted call without a reported loss, a phone scam involving lost money, a call for which you know information about the company or scammer, a robocall, or spoofing of your own number.
- Submit the FTC report that matches. Use DoNotCall.gov for an unwanted call without a reported loss. Use ReportFraud.ftc.gov for a loss or information about a scammer or company.
- Submit an FCC complaint when the telecom issue is relevant. Include unwanted calls, robocalls or spoofing. Select “my own number is being spoofed” when other people’s calls appear to come from your number.
- Describe caller ID cautiously. State what appeared on the screen and identify it as caller ID. Do not state that the displayed number identifies the caller.
- Ask the carrier about controls. Request the blocking, labeling or screening options available for your plan and device, and follow the carrier’s current activation instructions.
- Keep your submission details. Save the date you filed and the facts you submitted so later reports about related calls remain consistent. Do not promise yourself that a form submission will produce a personal response.
How to handle common call scenarios
A robocall shows a local number
Record your number, the local caller-ID number, any callback number in the recording, and the date and time. Submit the no-loss report through DoNotCall.gov and add an FCC complaint for the unwanted robocall. Treat the local appearance as a spoofing possibility, not proof that a nearby person called.
A caller claims to represent a company and you paid
Preserve the payment and call details and use ReportFraud.ftc.gov because money was lost. If the call was also an unwanted or spoofed robocall, submit the corresponding FCC complaint. Identify the claimed company separately from the caller-ID number; the two may not be connected.

This can indicate that your own number is being spoofed. Use the FCC complaint path for “my own number is being spoofed,” and record examples of the reports you receive. The caller-ID number shown to those people is not proof that your handset placed the calls.

A legitimate telemarketing company keeps calling
Check whether your number is on the National Do Not Call Registry. Registration can take up to 31 days to take effect for legitimate companies. Report continued unwanted sales calls through DoNotCall.gov and ask your carrier about a blocking or screening option if you want a device-level control.
The caller ID is not a normal U.S. number
Keep the number exactly as displayed. In the FCC form, use the “Additional Information” field when the number does not fit the usual format, as FCC guidance instructs. Do not replace it with a guessed U.S. number.
What happens after you submit
FTC reports are analyzed and shared
The FTC says it cannot respond individually to each report. It analyzes the reports and shares reported phone numbers with telecommunications carriers and other industry partners working on call blocking and call labeling. A report can therefore contribute to pattern detection without producing a message back to you.
Free tools Windows power users keep installed
One-click scans. No signup required.
FCC complaints inform policy and enforcement
The FCC uses complaint information for policy decisions and as a possible basis for enforcement against rule violations. Its stated role does not include resolving each individual unwanted-call complaint.
Carrier controls can change the experience on your line
A carrier feature may block, label or screen future calls, but the exact behavior depends on the carrier, plan and device. Ask support what will happen to unknown callers and how to reverse or adjust the setting before enabling it.
Current scale of the Do Not Call Registry
In the FTC’s January 2026 biennial Registry announcement, the agency reported more than 258 million telephone numbers on the National Do Not Call Registry at the end of fiscal year 2025 and more than 2.6 million Do Not Call complaints during fiscal year 2025. These are FTC counts of registered numbers and complaints, not counts of scam calls or people harmed.
Accuracy and privacy checks before filing
- Confirm that the receiving number is yours and is not the caller-ID number copied into the wrong field.
- Copy numbers rather than retyping them from memory.
- Mark a number as caller ID when you are unsure whether it is genuine.
- Distinguish the company the caller claimed to represent from the identity of the actual caller.
- Use the actual date and time when known; otherwise state that the timing is approximate or unknown.
- Do not add a person’s name, address or ownership claim merely because a spoofed number appears to belong to them.
When the U.S. routes do not apply
The FTC and FCC paths described here are U.S. federal routes. Other countries use different regulators, registries and privacy rules. Carrier support also varies by country, network and plan. If your line is outside the United States, identify the jurisdiction and carrier first rather than assuming that DoNotCall.gov, ReportFraud.ftc.gov or the FCC complaint categories are available to you.
