Wrong Number Text Scam: Why Not to Reply

A “wrong number” text from a stranger is often the first move in a scam, not a mistake. The FTC says these messages often evolve into a conversation with romantic undertones that can lead to investment and other scams, so I wouldn’t reply, even to say it’s the wrong number. Delete it, report it and block the sender.

What a wrong number text scam looks like

It’s a short, friendly message that seems meant for someone else. AARP lists examples such as “Hey, you coming for dinner tonight?”, “Oops, wrong number!” and “Hello.” (AARP). The FTC’s examples are “hi, how are you?” and a text asking when you’re free “to catch up over a cup of coffee” (FTC, FTC).

The CFTC’s investor alert says that fraudsters “might text a target pretending to be an old friend or claiming to have contacted the target accidentally,” and that some use an auto dialer to mass-send texts designed to look like messages meant for someone else (CFTC). FINRA says to be suspicious of unknown senders “especially if the message is vaguely worded or appears aimed at someone else” (FINRA).

What they want

The goal is a conversation. If you answer, AARP describes the next weeks: the sender builds a friendship, mentorship or romance, sometimes with fake photos, then describes a lifestyle funded by cryptocurrency and invites you to invest. Fake accounts may show big returns, and when you try to withdraw, you may be told to pay taxes first (AARP). The FTC puts it the same way: the sender tries to gain your trust and then pitches crypto investing for a fee (FTC).

The FBI says these schemes usually begin with a romance or confidence scam and become cryptocurrency investment fraud, with criminals building trust under fictitious identities. It reported that criminals defrauded victims of “more than two billion US dollars in 2022” (FBI IC3). The CFTC and FINRA call this family of scams relationship investment scams and mention the “distasteful term ‘pig butchering scams’” (FINRA).

For scale, the FTC said consumers reported losing “$470 million to scams that started with text messages” in 2024, and it listed “wrong number” scams among the frequently reported ones (FTC). That figure covers all text scams, not only this one.

Should you reply to a wrong number text?

I wouldn’t. The FTC’s reason is simple: “Even if you just reply to the text but don’t engage in conversation, you’ve still confirmed they reached a working telephone number,” which could lead to more calls and texts from scammers (FTC). The FTC also says scammers use these messages as “a conversation starter, so don’t text back.” AARP adds not to reply even with “STOP” (AARP).

It can feel rude to ignore someone who may have simply mistyped. The FTC has a whole alert on why it isn’t. If it was a real mistake, the sender will notice when nobody answers.

Warning signs after a reply

• The stranger keeps going. A real wrong number ends after one message.
• The chat moves to another app. FINRA says fraudsters “quickly move communications away from the initial platform to a different, sometimes unmonitored space” (FINRA). FINRA doesn’t name WhatsApp or Telegram, but I’d treat any request to switch apps from someone you’ve never met as that same sign.
• Easy money. FINRA: “Promises of high investment returns, with little or no risk, are classic warning signs of fraud.” The FTC: “Only scammers guarantee you’ll make lots of money in a short time with zero risk” (FINRA, FTC).
• Crypto or odd payment instructions. FINRA says an investment might not be legitimate if you’re required to pay for it with crypto assets, or asked to pay an unrelated business.
• A fee or tax to withdraw. The FBI says if you’ve already invested and suspect fraud, “do not pay any additional fees or taxes to withdraw your money” (FBI IC3).

What to do if you replied or sent money

1. Stop replying. Don’t send more money or share personal or financial information (FBI IC3).
2. Contact whoever moved the money, right away. The FTC says to report a bank transfer to your bank or credit union and ask them to reverse it; report a card payment to the card issuer; for crypto, contact the exchange or ATM operator and say it was fraudulent. It warns that cryptocurrency payments “don’t have the same legal protections as credit and debit cards do” (FTC). The CFTC is blunter: money sent by wire outside the U.S. or in crypto may mean “you likely will never see your money again” (CFTC).
3. Report to the FBI. File at ic3.gov. Include how the contact began, plus dates, amounts, account numbers and cryptocurrency addresses (FBI IC3).
4. Report to the FTC at ReportFraud.ftc.gov (FTC). For securities fraud, FINRA points to the SEC and its own complaint and tip forms.
5. Don’t click links the sender gave you (FTC). If you did, how to check if your iPhone is hacked is a calm place to start.

If you only replied once and nothing else happened, you don’t have much to undo. Block the number and don’t answer further.

How to report and block it on iPhone

1. Don’t reply. Don’t tap links.
2. Report it. The FTC says to delete the message and report it with your phone’s “report junk” option, or forward it to 7726 (SPAM) (FTC). Forwarding “helps your wireless provider spot and block similar messages” (FTC).
3. Tell the FTC at ReportFraud.ftc.gov (FTC).
4. Block the sender, and turn on filtering for unknown senders. The exact menus are in how to block spam calls on iPhone, which also covers reporting junk texts.

Blocking one number only goes so far, since the sender can text from another. It’s the same pattern as the toll and package texts in the unpaid toll scam text, and the hub, what is smishing, covers the whole family.

What Mistero can and can’t do here

Mistero can’t stop a scam text from being sent to you, can’t tell you whether a stranger is honest, and can’t get money back once it has been sent.

What the listing says is that on iPhone you can “enable caller identification, spam call blocking, and SMS filtering,” and that you can “Scan QR codes and review their links before opening them” (App Store listing, read Nov 4, 2026). Filtering is a help for unknown senders, not a substitute for not replying. More on Mistero security.
