Why Is a Local Area Code Calling Me? Neighbor Spoofing Explained

Say your number is 614-555-0172 and your phone lights up with 614-555-0139 (both made up): same area code, same next three digits, the exact match the FTC describes. It looks like someone down the street. It probably isn't. The FTC's name for this trick is neighbor spoofing: scammers fake the caller ID so it matches the first six digits of your own number.

The number on your screen may have nothing to do with the person dialing. The FCC says a neighbor-spoofed call can start overseas and still show up as coming from your own area code and local exchange.

Why the first six digits look like yours

A US number breaks into three parts: area code, then a three-digit central office code (the exchange or prefix), then four digits for the line. The first six digits are the part people recognize as "local," which is exactly the part a spoofer copies.

Copying only your area code is the looser version. The FTC describes both: a caller ID number with your area code, often matched to the first six digits of your number. If you want to see which codes belong to which region, our US area codes by state list and our page on the North American Numbering Plan show how the system is laid out. Our guide to how US area codes and overlays work covers why a single region can have more than one code.

Why scammers bother

Because local numbers get answered. The FTC puts it simply: a call that looks local is more likely to get answered, and scammers can easily fake caller ID. The FCC adds a second motive. Spoofing raises the chance you pick up and also makes you trust the call more once you do.

The local number is only the opening. From there, callers pose as someone you trust, such as a government agency, a police department, your bank or your cable company. Two tells are worth memorizing. Pressure to act immediately is, in the FTC's words, a sure sign of a scam. And if a recording asks you to press a button to stop future calls, or asks a question that invites a "yes," hang up. The FCC says scammers use those tricks to find live respondents or to use your "yes" for unauthorized charges.

The number being shown often belongs to a real person who has no idea it's being used. Calling back to complain usually reaches that person, not the scammer.

Is spoofing illegal?

When it's used to cheat people, yes. The FCC summarizes the Truth in Caller ID Act this way: it prohibits spoofing with the intent to cause harm, defraud or wrongfully obtain anything of value. The statute itself covers callers inside the US and callers outside it when the person receiving the call is in the US, for both voice and text messaging. FCC fines under that section can reach $10,000 per violation, or three times that for each day of a continuing violation, capped at $1,000,000 for a single act.

Not every altered caller ID breaks the law. The FCC notes spoofing technology has legitimate uses. Hiding your own number, so the call shows up as blocked or private, isn't a violation. Authorized law enforcement and intelligence work is also exempt.

What STIR/SHAKEN does, and what it doesn't

STIR/SHAKEN is the caller ID authentication framework US phone networks use. The name stands for secure telephone identity revisited and signature-based handling of asserted information using tokens. It works in two steps. The provider that originates a call attests to the accuracy of the caller ID it sends. The provider that delivers the call to you confirms that the caller ID was properly authenticated. FCC rules required voice providers, with some exceptions, to fully implement it on their internet Protocol networks by June 30, 2021.

Authentication doesn't block anything by itself. What it does is feed your carrier's filters. Terminating providers may block calls using reasonable analytics, those analytics must consider caller ID authentication information where it's available, and you must be able to opt out. Providers can also block calls that claim to come from invalid numbers or from numbers never allocated to any provider. A spoofed number that is real and in service, like your neighbor's, can still get through, which is why the steps below still matter.

What to do when a local number calls

1. Let it go to voicemail. The FTC's advice is to remember the number could be faked, and if you do answer and don't recognize the caller, hang up.
2. Don't use caller ID as proof. The FTC says it can be nearly impossible to tell whether caller ID information is real.
3. Verify on your own terms. If the caller claims to be from a company, hang up and call the number on its website or your latest bill.
4. Keep your details to yourself. The FTC says not to give out, or even confirm, personal or financial information to someone who calls, however local the number looks.

Missed calls from unfamiliar area codes can be a different scam. If the code turns out to be in the Caribbean, read our guide to one-ring scam calls before calling back.

Block, filter or label

The FTC lists your options: apps, features built into your phone, cloud-based services, call-blocking devices and services from your carrier. Some are free and some cost money. Blocking can catch calls you actually want. Labeling is the gentler version: the call still rings, but with a tag like "spam" or "scam likely."

• iPhone: the Silence setting sends calls from unsaved numbers to voicemail and still lists them in Recents. Ask Reason for Calling makes unknown callers explain themselves before the phone rings. The Spam filter silences calls your carrier flags as potential spam or fraud and moves them to a Spam list.
• Android (Google Phone app): caller ID and spam protection is on by default, and you can turn on Filter spam calls. Marking a number as spam stops more calls from it and reports it.

Since scammers can easily fake whatever number appears, blocking one spoofed number does little against the next call. Carrier and phone-level filters make more sense than a growing block list.

Report it

The National Do Not Call Registry won't stop scammers. Reporting still helps. If you didn't lose money, use the form at DoNotCall.gov. If you lost money or know something about the caller, go to ReportFraud.ftc.gov. Include the number that received the call, the number on your caller ID even if you think it's fake, any callback number you were given, and the date and time. You can also file a complaint with the FCC at consumercomplaints.fcc.gov.

When your number is the one being spoofed

Sometimes the calls go the other way: strangers phone you, annoyed, asking why you called them. That usually means a scammer put your number on their caller ID. You didn't do anything wrong. Keep the explanation short and don't share personal details with people you don't know. If the return calls pile up, your carrier's filtering tools are the place to start.

FAQ

Why do I get calls from numbers that look like mine?

Scammers copy your area code and often your first six digits, betting you'll answer a call that looks local.

Should I call back a local number that called me?

Not on the strength of the number alone. If it claims to be a company, call the number on the company's website or your bill instead.

Does STIR/SHAKEN stop spoofed calls?

It authenticates caller ID between providers, and carriers can use that result when deciding what to block. It isn't a guarantee on its own.
