Is my mobile number being used elsewhere?

[LJ123]

So I've had my new o2 iPhone 13 pro for just over 2 weeks. As soon as my phone got turned on I've started receiving continuous texts from a so called Samsung Verification with a 2fa code and at the end of each text is bP2ROrn3fZQ. 

To top it off I get phone calls from South Korea, on entering bP2ROrn3fZQ and my number into Google I've found the following:

and

Please tell me o2 don't give me a recycled number or one that is being used a temporarily used one

All numbers are recycled as there are not enough new ones available

O2 will change your number for free if you ask them.
