Got a verification code you didn’t ask for? What it means
In short
- Often someone typed your number by mistake when signing up or logging in. Ignore it.
- Never share the code with anyone, even someone who says they sent it to you by mistake.
- If codes keep coming for an account of yours, change its password and turn on two-factor authentication.
A code you didn’t ask for is usually a mistake, sometimes a warning, and occasionally the first step of a scam.
Usually, a typo
Apps send a code to whatever number is typed in. If someone mistypes their own number, the code comes to you. Snapchat’s help centre, for one, says someone may have entered your number by mistake, and advises not to interact or share the code.
Sometimes, someone trying your account
If the code is for an app you use, someone may be trying to sign in to your account or reset its password. The code on its own can’t get them in; they need you to pass it on.
Never share it
The US Federal Trade Commission’s advice is plain: don’t share a verification code with anyone who contacted you, as that’s a scam every time. A message saying “I sent my code to your number by mistake, can you forward it?” is the classic version. Our guide to the verification code scam explains how it works.
What to do
- Don’t reply, don’t tap any link, and don’t forward the code.
- If it’s an app you use, change its password and turn on two-factor authentication, ideally with an authenticator app.
- Check the app’s list of signed-in devices, and sign out any you don’t recognise.
Fewer apps with your number
The fewer sign-ups carry your own number, the fewer places can leak it or send it codes. For one-off sign-ups, a one-time number keeps yours private: ours start at $1, and the money goes back to your balance if no code arrives within 20 minutes. See also how to keep your number private.
Common questions
Is it dangerous to get a verification code I didn’t request?
The code alone can’t do anything. The risk is someone persuading you to share it, so don’t reply, and don’t pass it on.
Someone says they sent their code to my number by mistake. Should I forward it?
No. That’s a known scam: the code can open an account linked to your number. The US Federal Trade Commission’s advice is never to share a verification code with someone who contacted you.
Why do I keep getting codes for an account I have?
Someone may be trying to sign in. Change the password, turn on two-factor authentication with an authenticator app, and check the account’s sign-in activity.
