u shouldnt really need to worry about the psn ea code. since like it says on lodestone:

Users who purchase digitally from PlayStation Store will not need to enter an early access code, or a full promotion code at launch, as it is included as part of your purchase and will automatically flag your Sony Entertainment Network account.

so on 19th the code should be out of pending and actually approved when servers goes live.

for physical if u got it from se store then should be sent a few hrs before early access like what happen with ARR
