What to Do If a Scammer Has Your Phone Number

When a scammer gets hold of your phone number, it's not just an annoyance—it's a potential gateway to identity theft, financial fraud, and a cascade of security compromises. Your phone number has become one of the most valuable pieces of personal information in the digital age, serving as a key to your two-factor authentication, password resets, and even your financial accounts. Understanding what scammers can do with this information and how to protect yourself is critical in 2024's threat landscape.

What Happens When a Scammer Has Your Phone Number

A phone number compromised scenario is more serious than most people realize. Your phone number isn't just a way to reach you—it's become a primary identifier that connects your digital identity across dozens of platforms and services.

When a scammer has your phone number, they can execute several attack vectors:

SIM Swapping Attacks: Scammers contact your mobile carrier, impersonate you using personal information gathered from data brokers, and convince the carrier to transfer your number to a SIM card they control. Once successful, they receive all your calls and texts, including two-factor authentication codes. The FBI's Internet Crime Complaint Center (IC3) reported that SIM swapping complaints resulted in over $68 million in losses in 2021 alone.

Smishing (SMS Phishing): You'll receive text messages that appear to come from legitimate organizations—banks, government agencies, or delivery services—containing malicious links or requesting sensitive information. The FTC reported that consumers lost $330 million to text message scams in 2022, a 50% increase from the previous year.

Voice Phishing (Vishing): Scammers call pretending to be from your bank, the IRS, or tech support. They use social engineering tactics, often creating urgency ("Your account has been compromised!") to trick you into revealing passwords, account numbers, or other sensitive data.

Account Takeover Attempts: With your phone number, scammers can attempt password resets on your email, social media, and financial accounts. Many platforms send verification codes via SMS, which becomes a vulnerability when your number is compromised.

Caller ID Spoofing: Scammers can make it appear that calls are coming from your number, damaging your reputation and potentially scamming people in your contact list who trust calls from your number.

The root problem? Data brokers collect and sell your phone number along with associated personal information—your address, email, age, relatives, and more—making it easier for scammers to build convincing impersonation attacks. These brokers aggregate data from public records, online activity, purchase history, and other sources, creating detailed profiles that end up in the hands of anyone willing to pay.

Real-World Examples of Phone Number Scams

Understanding how these scams play out in reality helps you recognize them when they target you.

The Bank Verification Scam: Sarah, a marketing professional in Austin, received a text that appeared to come from her bank's official number: "Unusual activity detected on your account. Verify your identity here: [link]." The link led to a convincing replica of her bank's website. She entered her credentials and immediately received a call from someone claiming to be bank security, who already knew her name, partial account number, and recent transaction—all information purchased from data brokers. The caller requested a verification code that had just been texted to her. That code was actually for changing her account password. Within minutes, $4,700 was transferred out of her account.

The IRS Impersonation Call: Michael received a call from a number showing "Internal Revenue Service" on his caller ID. The aggressive caller claimed he owed back taxes and would be arrested within hours unless he paid immediately via gift cards. The scammer knew his full name, address, and approximate income—details easily purchased from data broker networks. While Michael didn't fall for it, the FTC reports that impersonation scams cost Americans over $2.6 billion in 2022.

The SIM Swap Cryptocurrency Theft: A cryptocurrency investor in California lost over $100,000 when scammers executed a SIM swap attack. The attackers had purchased his personal information from data brokers, including his phone number, address, date of birth, and even his mother's maiden name. They used this information to convince his mobile carrier they were him, ported his number to their device, and then reset passwords on his cryptocurrency exchange accounts using SMS verification codes.

The Family Emergency Scam: An elderly couple received a frantic call from someone claiming to be their grandson, saying he'd been arrested and needed bail money immediately. The scammer had enough information—including family member names obtained from people-search sites—to make the story convincing. They wired $8,000 before reaching their actual grandson and discovering the fraud.

Red Flags: How to Spot Phone Number Scams Instantly

Recognizing these warning signs can prevent you from becoming a victim:

Urgency and Pressure Tactics: Legitimate organizations don't create artificial deadlines or threaten immediate consequences. If someone says "act now or your account will be closed," "you'll be arrested within the hour," or "this offer expires in 10 minutes," it's almost certainly a scam.

Requests for Verification Codes: No legitimate company will ever ask you to share a verification code you just received via text or email. These codes are meant for your eyes only. If someone asks for one, they're attempting account takeover.

Unsolicited Contact About Security Issues: Real banks and service providers don't call, text, or email out of the blue about security problems. They'll ask you to log in through official channels or visit a branch. If you receive unexpected contact about account issues, hang up and call the official number yourself.

Requests for Payment via Gift Cards, Wire Transfer, or Cryptocurrency: Government agencies and legitimate businesses never demand payment through these methods. The IRS doesn't accept iTunes gift cards. Your bank doesn't want Amazon gift codes. These payment methods are irreversible and untraceable—exactly what scammers want.

Caller ID Showing Your Own Number: If you receive a call from your own phone number, it's spoofed. Answer it and you'll typically hear a scam pitch. This is a clear sign of scammer phone tactics.

Too Much Personal Information: If a caller knows details about you that seem oddly specific (your relatives' names, recent purchases, your workplace), they likely bought your information from data brokers. This doesn't make them legitimate—it makes them well-prepared scammers.

Generic Greetings: Legitimate organizations use your name. Scammers often use "Dear Customer," "Account Holder," or "Valued Member" because they're sending mass messages.

Suspicious Links: Before clicking any link in a text message, press and hold it to preview the full URL. Look for misspellings (amaz0n.com instead of amazon.com), unusual domains, or shortened links (bit.ly, tinyurl) that hide the destination.

What to Do If You've Been Targeted

If you suspect a scammer has your phone number or you've already fallen victim, take these immediate steps:

Immediate Actions (First 24 Hours)

1. Don't Engage Further: If you're on the phone with a suspected scammer, hang up immediately. Don't press any numbers, don't say "yes" (which can be recorded and used fraudulently), and don't provide any information. For text messages, don't click links or reply—even "STOP" confirms your number is active.

2. Contact Your Mobile Carrier: Call your carrier's customer service (use the number on your bill, not one provided by the caller) and request:

- A port freeze or number lock to prevent SIM swapping

- Review of recent account changes or access attempts

- Addition of a PIN or password required for any account modifications

- Notification alerts for any account changes

For major carriers:

• Verizon: Call 1-800-922-0204 or visit a corporate store to add a Number Lock
• AT&T: Call 611 from your phone or 1-800-331-0500 to set up extra security
• T-Mobile: Call 611 or 1-800-937-8997 to enable Account Takeover Protection
• Google Fi: Access security settings at fi.google.com/account/security

3. Enable Two-Factor Authentication (But Not SMS): While it seems counterintuitive, you need stronger authentication than SMS. Use authenticator apps (Google Authenticator, Authy, Microsoft Authenticator) or hardware security keys (YubiKey, Google Titan) for important accounts. These aren't vulnerable to SIM swapping.

4. Check Your Accounts: Immediately review:

- Bank and credit card accounts for unauthorized transactions

- Email accounts for password reset requests or forwarding rules

- Social media accounts for unauthorized posts or messages

- Phone bill for unusual calls, texts, or data usage

5. Change Critical Passwords: Update passwords for:

- Email accounts (do this first—email controls password resets for everything else)

- Financial accounts

- Any account using your phone number for recovery

- Accounts with stored payment information

Use a password manager to create unique, complex passwords for each account.

Short-Term Protection (First Week)

6. Place a Fraud Alert: Contact one of the three major credit bureaus to place a fraud alert on your credit report. The bureau you contact must notify the other two:

- Equifax: 1-888-766-0008 or equifax.com/personal/credit-report-services

- Experian: 1-888-397-3742 or experian.com/fraud

- TransUnion: 1-800-680-7289 or transunion.com/fraud

A fraud alert is free and lasts one year, requiring creditors to verify your identity before opening new accounts.

7. Consider a Credit Freeze: A freeze is stronger than a fraud alert, preventing anyone (including you) from accessing your credit report until you lift it with a PIN. This stops scammers from opening new accounts in your name. Request freezes at all three bureaus:

- Equifax: equifax.com/personal/credit-report-services/credit-freeze

- Experian: experian.com/freeze

- TransUnion: transunion.com/credit-freeze

8. Monitor Your Credit: Get your free credit reports at annualcreditreport.com (the only official site for free reports) and review them for unauthorized accounts or inquiries.

9. Document Everything: Keep records of:

- Dates and times of suspicious calls or texts

- Phone numbers used (even if spoofed)

- Names and details provided by scammers

- Screenshots of suspicious messages

- Financial losses and affected accounts

This documentation is crucial for reporting and potential restitution.

Long-Term Protection

10. Remove Your Information from Data Brokers: This is the most important long-term step. Scammers found your phone number and associated personal information through data broker sites. These companies collect and sell your data to anyone, including criminals.

Manually opting out of data brokers is time-consuming—the average person appears on 50-100 broker sites, each with different opt-out processes. Some require mailing notarized documents. Others re-add your information within months. A free scan can show you exactly where your information appears across 2,100+ data broker sites.

Services like GhostMyData automate this process, using AI agents to continuously monitor and remove your information from data brokers. Unlike competitors that cover only 35-500 brokers, comprehensive coverage is essential—scammers use whichever source provides your data.

How to Report Phone Number Scams

Reporting scams helps authorities track patterns and potentially catch perpetrators. It also creates official documentation of the crime.

Federal Trade Commission (FTC): Report all scam calls and texts at reportfraud.ftc.gov or call 1-877-FTC-HELP. The FTC uses these reports to investigate and prosecute scammers. If you lost money, you may be eligible for compensation through FTC settlements.

FBI Internet Crime Complaint Center (IC3): For significant financial losses or sophisticated scams like SIM swapping, file a report at ic3.gov. Include all documentation and evidence.

Your State Attorney General: Many states have consumer protection divisions that investigate scams. Find your state AG at naag.org/find-my-ag.

Federal Communications Commission (FCC): Report unwanted calls and texts at consumercomplaints.fcc.gov or call 1-888-CALL-FCC. The FCC enforces rules against robocalls and caller ID spoofing.

Your Mobile Carrier: Report the scam to your carrier's spam or fraud department. For text scams, forward the message to 7726 (SPAM) on most carriers. This helps carriers block scammers.

IRS (for tax scams): Report IRS impersonation scams at treasury.gov/tigta or call 1-800-366-4484.

Social Security Administration (for SSA scams): Report Social Security scams at oig.ssa.gov/report or call 1-800-269-0271.

Your Bank or Credit Card Company: If financial accounts were compromised, report it immediately to their fraud department. You typically have 60 days to dispute unauthorized charges, but faster reporting improves recovery chances.

Local Police: For significant financial losses or if you have identifying information about the scammer, file a police report. While local police rarely catch phone scammers, the report creates official documentation for insurance claims, credit disputes, and legal proceedings.

How to Protect Yourself Going Forward

Prevention is more effective than recovery. These strategies significantly reduce your risk of future phone number compromised scenarios.

Strengthen Your Phone Security

Use a Virtual Phone Number: Services like Google Voice, Burner, or MySudo provide alternative numbers for online accounts, shopping, and situations where you don't want to share your real number. If these numbers are compromised, you can simply change them without affecting your primary number.

Set Up Carrier-Level Protection: Beyond the initial port freeze, enable:

- Call filtering services (Verizon Call Filter, AT&T Call Protect, T-Mobile Scam Shield)

- Account alerts for any changes

- Multi-factor authentication on your carrier account itself

Use Call Screening: Enable built-in call screening on Android phones or use apps like Truecaller, Nomorobo, or Hiya to identify and block known scam numbers.

Register with the National Do Not Call Registry: While it won't stop scammers (who ignore the law), register at donotcall.gov or call 1-888-382-1222. This reduces legitimate telemarketing and makes it easier to identify remaining calls as suspicious.

Secure Your Accounts Properly

Migrate Away from SMS Two-Factor Authentication: SMS-based 2FA is better than nothing, but it's vulnerable to SIM swapping. Prioritize:

1. Hardware security keys (highest security) - YubiKey, Google Titan, or Thetis

2. Authenticator apps (strong security) - Google Authenticator, Authy, Microsoft Authenticator

3. SMS codes (weakest option) - only if nothing else is available

Use Unique Passwords Everywhere: A password manager (1Password, Bitwarden, Dashlane) generates and stores complex, unique passwords for every account. If one site is breached, your other accounts remain secure.

Set Up Alternative Recovery Methods: Instead of phone number recovery, use:

- Recovery email addresses (separate from your primary email)

- Security questions with fake answers stored in your password manager

- Backup codes stored securely offline

Review Account Security Settings: For critical accounts (email, banking, social media), regularly review:

- Connected devices and active sessions

- Recovery options and backup contact methods

- Privacy settings and data sharing preferences

- Third-party app access and permissions

Reduce Your Data Exposure

The most effective long-term protection is reducing the personal information available to scammers in the first place.

Audit Your Digital Footprint: Search for yourself on Google, Bing, and people-search sites like Whitepages, Spokeo, and BeenVerified. You'll likely be shocked at how much information is publicly available—phone numbers, addresses, relatives, property records, and more.

Opt Out of Data Brokers: This is where scammers get the information that makes their attacks convincing. Data brokers aggregate information from:

- Public records (property deeds, voter registration, court records)

- Online activity (browsing history, purchases, app usage)

- Social media (posts, likes, connections, check-ins)

- Loyalty programs and surveys

- Other data brokers (they trade information with each other)

The California Consumer Privacy Act (CCPA) gives California residents the right to request deletion of their personal information from data brokers. The Virginia Consumer Data Protection Act (VCDPA), Colorado Privacy Act (CPA), Connecticut Data Privacy Act (CTDPA), and Utah Consumer Privacy Act (UCPA) provide similar rights to residents of those states. Even if you're not in these states, many brokers will honor opt-out requests.

However, manually opting out is a Sisyphean task. There are over 2,100 known data broker sites, each with different opt-out procedures. Some require:

- Mailing notarized documents

- Providing additional personal information (ironically)

- Waiting 30-90 days for removal

- Repeating the process quarterly as information reappears
