Seems to be some sort of Yahoo Mail login code scam. Sends a code from a mobile number. Do not attempt to use these codes. Wait and press resend code on yahoo login page and wait for a code to be received from “Yahoo”.

I was sent a code when not using the computer or phone. number blocked.

Yes. I agree. This number only sends 5 digits, yahoo sends 6. Resend to get yahoo 6 digit code.

Same scammers rang me first on 048597135* group of numbers, said from Telstra giving discount. Then knew email address and name. Send a SMS code thru this number while on phone with them saying it’s from yahoo but it isn’t yahoo. Hung up at this stage and changed passwords on email accounts.
