Verification or Phishing?

• Before receiving this email, I’ve only re-verified the email address but not the phone number because the phone number we originally had on the account was a landline (company phone number). For verifications like this we used to be able to get the OTP from a robotic call but it seems like this time Amazon refuses to deal with anything other than an SMS to a mobile number. (Just as @Dreamscape-Studio described in this thread)
• It would be simple if we just use a mobile and be done with it, but things are also kinda complicated, so I just left the phone number un-re-verified(?) as it is for 2 months.

That’s the situation I am in. I attempted to verify that phone, but nothing happens. So I assume they are attempting to text a landlne phone.

When I have to get a code to sign in (not often – maybe every ten days or so) – the process works fine – landline rings, recording gives me my code.

So I have left it “unverified”.
