How can I access my old iCloud?

I haven’t been able to access my old account for about 2 years and I decided I would finally ask on here. I know my password and everything but when it says I need to get a verification code it’s supposed to go to a phone, which my iCloud isn’t linked to one anymore. The number was also not mine because at the time I had no number and there’s no other options like answer security questions or anything so please if anyone can help out it would be appreciated.
