2 accounts on 2 different platforms

sorry to be a pain was just wondering how linking your number works I want to keep my ps4 account (main account) but switched pc a while ago I bought the watchpoint pack on pc does that mean im stuck using my new pc account or can I choose to use my ps4 account because there’s 6 years of progress I don’t want to lose

Unless they introduce a way to link your accounts together under 1 profile (something I really want), you’ll likely need 2 phone numbers.
