Hi @Whispering_Gemstone6406,
Thank you for reaching out. We can understand how unsettling this must be, getting sign-in codes again and again that you never asked for, especially when you don't even have an Adobe account.
We checked on our end and don't find any Adobe account tied to the details you've shared here. Just so you know, a one-time code like this only gets generated when someone tries signing in to an account that has two-step verification turned on for that number. So kindly do not enter the code anywhere, and please avoid tapping on any links in these messages.
If you'd like to report this further, do write in to our phishing team at phishing@adobe.com with the details.
Do let us know how it goes, happy to help further.
Thanks,
^AV
