Written by: The Phone Privacy Protector
The phone rings. The caller says they’re from your bank. They need to verify your account number. Or they’re from Medicare updating your records. Or they’re from your credit card company confirming suspicious activity.
They sound professional. They know some of your information. They create urgency. And they ask you to confirm personal details “for security purposes.”
Here’s the truth: Legitimate organizations already have your information. They don’t call asking you to verify what they already know. When someone calls requesting personal information, it’s almost always a scam.
Sharing certain information over the phone can empty your bank accounts, destroy your credit, steal your medical benefits, and take years to repair. But knowing what never to share—and why—protects you completely.

- Safe ways to handle legitimate requests
Information You Should NEVER Share Over the Phone
1. Social Security Number
Why it’s dangerous: Your SSN is the master key to your identity. With it, criminals can:
- Open credit cards in your name
- Take out loans
- File fake tax returns
- Access your Social Security benefits
- Steal your medical benefits
- Apply for government assistance using your identity
Who legitimately needs it: Almost no one by phone. The Social Security Administration already has it. The IRS has it. Your bank has it.
What to do instead: If someone claims they need your SSN, hang up. Look up the official number yourself and call back to verify the request is legitimate.
Exception: You called them first for a specific reason and initiated the transaction.
2. Bank Account Numbers
Why it’s dangerous: With your account number and routing number, criminals can:
- Set up automatic withdrawals
- Create counterfeit checks
- Empty your account
- Link your account to payment apps
Who legitimately needs it: Almost never over incoming calls. Your bank already has this information.
What to do instead: Never give account numbers to incoming callers. If your bank needs to verify something, they can ask for partial numbers (last 4 digits) or other information they already have.
Safe scenario: You called your bank to set up a legitimate payment or transfer and initiated the call yourself.
3. Credit Card Numbers and CVV Codes
Why it’s dangerous: Full credit card details allow criminals to:
- Make online purchases
- Sell your card information on the dark web
- Clone your card
- Set up recurring charges
The CVV code (3-digit security code on back) is specifically designed to never be shared over the phone or stored.
Who legitimately needs it: Only merchants you called to make a purchase you initiated.
What to do instead: Never give full card numbers to incoming callers. Even if they claim there’s suspicious activity, hang up and call the number on your card.
4. Online Banking Passwords or PINs
Why it’s dangerous: This is direct access to your money. No legitimate organization ever asks for passwords or PINs.
Banks specifically tell you to never share passwords. If someone asks for your password or PIN, they’re absolutely trying to steal from you.
Who legitimately needs it: No one. Ever. Not even your bank.
What to do: Hang up immediately if anyone asks for your password or PIN.
5. Medicare Number
Why it’s dangerous: Medicare fraud is a billion-dollar crime. With your Medicare number, criminals can:
- Bill Medicare for services you never received
- Steal your benefits
- Use your insurance for expensive treatments
- Sell your information to corrupt medical providers
Who legitimately needs it: Your doctor’s office when you initiated the appointment. Not random callers.
What to do instead: Medicare never calls to ask for your number. They already have it. Hang up on anyone claiming to be from Medicare requesting your number.
6. Driver’s License Number
Why it’s dangerous: Combined with other information, your driver’s license number helps criminals:
- Steal your full identity
- Create fake IDs
- Access government services
- Pass background checks using your identity
Who legitimately needs it: DMV, police during traffic stops, some government agencies—but rarely over the phone.
What to do instead: Ask why they need it and verify the caller’s legitimacy before sharing.
7. Verification Codes Sent to Your Phone
Why it’s dangerous: When you receive a text with a verification code, someone is trying to access your account. If you give that code to a caller:
- They gain access to your account
- They can change your password
- They can lock you out
- They can steal money or information
The scam: Caller says they’re from your bank and just sent you a verification code “for security.” They ask you to read it back. They’re actually using that code to break into your account.
What to do: Never share verification codes with anyone who calls you. Even if they claim to be from your bank.
8. Answers to Security Questions
Why it’s dangerous: Security question answers are used to reset passwords and verify identity. Sharing them gives criminals the keys to your accounts.
Common security questions:
- Mother’s maiden name
- First pet’s name
- Street you grew up on
- Favorite teacher
- High school mascot
What to do instead: Never answer these questions from incoming callers. If verification is needed, suggest alternative methods or offer to call back.
9. Current Location or Travel Plans
Why it’s dangerous: Criminals use this information to:
- Know when your house is empty for burglary
- Target you for scams when you’re vulnerable (traveling)
- Create convincing kidnapping scams targeting your family
- Track your movements
What to do instead: Keep travel plans private. Don’t post on social media about vacations until you return. Don’t tell callers you’re home alone or traveling.
10. Information About Your Computer or Phone
Why it’s dangerous: “Tech support” scammers call claiming they detected problems with your computer. They ask about:
- What operating system you have
- What antivirus you use
- What error messages you’ve seen
- If you’ve noticed slowness
They use this information to sound credible, then convince you to give them remote access.
What to do: Real tech companies never call unsolicited. Hang up. If you have computer concerns, call a local tech person you trust.
How to Verify Legitimate Callers
Never trust caller ID: Scammers fake caller ID to show banks, government agencies, or local numbers.
The verification process:
Step 1: Let them state their reason for calling.
Step 2: Get their name, department, and callback number.
Step 3: Tell them you’ll call back.
Step 4: Look up the official number yourself (don’t use the number they gave).
Step 5: Call the official number and ask to be transferred to that person or department.
Step 6: Verify the original call was legitimate.
Legitimate callers understand this process. Scammers get angry and pushy.
What Legitimate Organizations Actually Do
Your bank: Never asks for full account numbers or passwords, never demands immediate action, allows you to call back at official number.
The IRS: Always contacts by mail first, never threatens immediate arrest, never demands gift cards, gives you time to respond.
Social Security Administration: Sends letters for important issues, never threatens benefit suspension by phone, already has your SSN.
Medicare: Never calls asking for your Medicare number, your card doesn’t expire, you contact them first.
Utility companies: Send multiple notices before disconnection, accept various payment methods, allow website verification.
Red Flags That Indicate a Scam
Urgency and pressure: “Your account will be closed today!” Legitimate organizations give you time.
Threats: “You’ll be arrested!” Real agencies don’t threaten arrest by phone.
Unusual payment: “Pay with iTunes gift cards.” No legitimate organization accepts gift cards.
Request for secrecy: “Don’t tell anyone.” Scammers isolate you from people who might warn you.
Too good to be true: “You’ve won a prize!” You can’t win contests you didn’t enter.
Anger when questioned: Legitimate representatives stay professional. Scammers get hostile.
What to Do If You’ve Already Shared Information
If you shared your Social Security number:
- Place fraud alert with credit bureaus (Equifax, Experian, TransUnion)
- Monitor credit reports for new accounts
- File report at IdentityTheft.gov
- Consider credit freeze
- Monitor Social Security benefits statement
If you shared bank account or credit card information:
- Call your bank immediately
- Close compromised accounts
- Open new accounts with new numbers
- Monitor accounts daily for fraudulent activity
- Report fraud to bank’s fraud department
If you shared passwords or verification codes:
- Change passwords immediately from clean device
- Enable two-factor authentication
- Check account activity for unauthorized access
- Monitor accounts closely for several months
If you shared Medicare number:
- Call Medicare at 1-800-633-4227
- Check Medicare Summary Notice for fraudulent claims
- Report fraud at medicare.gov
- Consider requesting new Medicare number (difficult but possible in fraud cases)
Time is critical. Act within hours, not days.
Safe Ways to Handle Legitimate Requests
Option 1: You initiate the call – Call the official number yourself. Safe to provide necessary information when you start the contact.
Option 2: Use secure online portals – Log into your account through the official website (type address yourself, don’t click links).
Option 3: Visit in person – For sensitive matters, visit bank branches or government offices.
Option 4: Secure mail – Send information by certified mail with tracking.
Teaching Yourself to Say No
Practice these responses:
“I don’t provide personal information over the phone.”
“I’ll call you back at your official number.”
“I’m not comfortable sharing that right now.”
“Send me something in writing.”
“Let me speak with my family first.”
You don’t owe callers explanations. Protecting your information is more important than being polite.
