Binance text message

I just received text message from binance even tho I didn’t know what it was until I just googled it. They sent me 6 digit code and if I did not request it to call some number they also wrote in the text. Has this happened to anyone? I’m not planing on calling random numbers ofc or answering that text. Just wanted to be sure I’m safe and no one is using my phone number or something like that?
