Early Access is just the pre-order code. SB access will be removed if you don't add the actual retail code onto your account before the grace period is up which is around 3 days or June 23rd.

The other platforms you need to enter the retail code from the vendor before you actually technically have SB on your account. It is separate from the pre-order/EA code.

PSN doesn't need you to enter a code since they just flag your account with it when you purchase it automatically.
