“Hi Mom, This Is My New Number” — Is It Really Your Child?
Sample text (a made-up example, not a real message):
“Hi Mom, it's me. I dropped my phone and this is my new number, you can delete the old one. I need help with a bill I can't pay from this phone — can you send it just this once? Please don't tell Dad yet.”
Short answer: Do not send money from the new number's instructions, and do not delete the old number. Call your child on the old number you already trust. In most cases they answer, have a working phone, and have no idea what you are talking about.
This scam is different from the “grandchild in trouble” call on our grandparent scam page. That one is a phone call from a supposed grandchild in an emergency. This one is a text, usually to a parent, from a “new number,” and it works more slowly: a friendly chat first, then a bill that cannot wait. The victim here is a parent, the channel is text or WhatsApp, and the script is a broken phone, not a bail payment.
How the trick unfolds
- The warm opener. A message from a number you do not recognize says it is your son or daughter, that their phone broke or was lost, and that this is their new number. It may ask you to delete the old number. Do not.
- The friendly chat. A little back-and-forth builds trust. The “child” may know a first name, or a detail from social media. Knowing a name proves nothing — names are easy to find.
- The bill that cannot wait. A bill, rent, or a new phone must be paid today, but the banking app “does not work on the new phone.” The payment usually has to go somewhere unusual: another person's account, a payment app, gift cards, or crypto.
- The secrecy request. “Don't tell Dad,” or “don't tell anyone yet.” Secrecy is part of the scam, not a family confidence. A real child in trouble does not need you to hide the problem from the rest of the family.
Some versions now use a voice note that sounds like your child. A familiar voice is no longer proof of identity on its own. The check below still works, because it does not rely on the voice at all.
The one check that settles it
Call your child on the old number you already have saved. Do not use any number, link, or contact the new message gives you. If you cannot reach them, call another family member, or ask the “child” a question only your real child would know — and do not accept a vague answer. While you wait for an answer, send nothing.
Set up a family code word now, before any message arrives: one word or phrase your family agrees to use when a request for money comes from a new number. A scammer cannot guess it, and a real child can say it in seconds. Tell your children about this scam too — the best defense is a family that has already talked about it.
Never share a verification code
If the “child” asks you to read back a code sent to your phone — for WhatsApp, your bank, or any account — stop. That code is the key to your account, and no genuine child, friend, or support team ever needs it. Sharing it can lock you out of your own account and let the scammer message your contacts pretending to be you.
If you already sent money
Call your bank or card company first, using the number on the back of your card, and ask what can still be stopped. If you sent a payment-app transfer, contact the app's support as well and ask the same question. Save the messages, the number, and the payment details, then report to the FTC at ReportFraud.ftc.gov and to the FBI at ic3.gov. If you want guidance after a fraud, call the Elder Fraud Hotline at 1-833-372-8311. Our Sent Money guide walks through the bank call by payment type. If you only clicked a link and sent nothing, start with our scam recovery guide instead.

Check It Now — Free →A text says my child has a new number. How do I know if it is real?
Call your child on the old number you already have saved. If they answer and their phone works, the new-number message was a scam. Do not delete the old number, and do not send money from the new message's instructions.
What if my child really did get a new phone?
Then they can still prove it: they can answer on the old number once, call you from a number you recognize, or say your family code word. A real child will not mind you checking. A scammer will rush you past the check.
Why does the message ask me not to tell anyone?
Because one other family member would spot the trick. Secrecy is part of the scam. Tell another family member right away, even if the message asked you not to.
Should I reply to ask who it is?
You can ask a question only your real child would know, but do not send money, personal details, or any verification code while you wait for an answer. If the answer is vague, or they cannot talk on the phone, treat it as a scam.
The voice note sounds exactly like my child. Is it real?
Not necessarily. Voice-cloning tools can now copy a familiar voice from a short recording. A voice alone is no longer proof. Use the old-number call or the family code word instead.
I already sent money to a new-number message. What do I do first?
Call your bank or card company first, using the number on the back of your card, and ask what can still be stopped. Save the messages and payment details, then report to the FTC and the FBI.
