Spam calls are easy to place at scale, and caller ID can be faked to make a call look local or familiar. The U.S. National Do Not Call Registry can reduce many lawful sales calls, but it cannot stop scammers who ignore the rules. Blocking, screening and reporting can help limit the disruption, though none guarantees that every unwanted call will disappear.
Why do I get so many spam calls?
Automated dialing technology allows callers to place large numbers of prerecorded calls at relatively little expense, according to the Federal Trade Commission (FTC). That makes mass calling practical for telemarketers and for people making illegal robocalls. It does not mean every unwanted call is automated: some are live sales calls, and the technology behind any one call is not usually apparent to the person receiving it.

There is no reliable way to infer from a call alone that your number was sold, leaked or selected for a particular reason. A burst of calls can be frustrating, but it does not by itself establish how the callers obtained your number.

Scammers can spoof caller ID, changing the number or name displayed on your phone. They may use a number with your area code or a nearby prefix to make a call seem familiar. The displayed number is not proof of the caller’s identity; the FTC warns that caller ID is easy to fake, even when a call appears to come from a nearby number or a company you know.

#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.
Because the displayed number may belong to someone unrelated to the caller, do not assume that calling it back will reach the person who placed the call. If a caller claims to represent a business or agency, end the call and use contact details you find independently rather than relying on the caller ID or a number given during the call.
Does the Do Not Call Registry stop spam calls?
The U.S. National Do Not Call Registry is meant to stop most sales calls from real companies that follow the law. It is not a filter that blocks calls on your phone, and it does not prevent illegal callers from disregarding the rules. Registration can reduce lawful telemarketing calls, but it cannot be relied on as a shield against scams or every unwanted call. National Do Not Call Registry

FTC figures help put reports in context, but they are not a count of all calls. In fiscal year 2025, the FTC received more than 2.6 million Do Not Call complaints and the Registry had more than 258 million active registrations. The agency describes complaints as unverified consumer reports, not survey results; they should not be read as the number of calls U.S. residents received. The FTC also said reports of unwanted calls in FY 2025 were about 48% lower than in FY 2021, when it received approximately five million reports. That comparison is about reports to the agency, not a measured decline in every call made or received. FTC National Do Not Call Registry Data Book, FY 2025
Robocall complaints ticked up in FY 2025 but remained substantially below their FY 2017 peak, according to the FTC’s reporting. These are complaint trends, not a direct count of robocalls. FTC press releases

How can I reduce unwanted calls?
Use a mix of screening and caution. Blocking or labeling tools may reduce interruptions, while the Registry addresses lawful sales calls; neither makes every call safe or guarantees that all unwanted calls will stop.
- Hang up on suspicious robocalls. Do not press a key to reach a representative or ask to be removed. The FTC warns that responding can lead to more calls.
- Use your phone or carrier’s call controls. Check the current call-blocking and call-labeling options available for your mobile service or landline. Blocking rejects calls; labeling warns you about them without necessarily stopping them. Filtering may also block or flag a wanted call, so review settings and missed calls if you are expecting important contact.
- Keep the Registry in perspective. Registering can help reduce lawful telemarketing, but it will not stop illegal callers who ignore the law.
- Do not treat a familiar caller ID as verification. If the call claims urgency or asks for personal or financial information, hang up and contact the organization using a number from its official website, statement or card.
How do I report unwanted calls?
In the United States, report unwanted telemarketing calls at DoNotCall.gov. If the caller was involved in a scam and you lost money or have information about the scammer, report it at ReportFraud.ftc.gov. A report does not guarantee that the FTC will stop a caller or respond individually, but reports can help identify patterns and support enforcement and call-blocking or labeling efforts.
