How to redeem a PlayStation Store voucher code from buzai232's blog

As we prepare to launch the new PlayStation Plus membership service, we are doing some work behind the scenes to make the transition as smooth as possible for all of our existing members. As part of this work, we’ve temporarily disabled stacking memberships for existing customers until after the launch. Rest assured that your voucher code is still valid, and you will be able to redeem your code either when your existing membership expires and deactivates, or after the new PlayStation Plus service launches in your area, whichever happens first.

If you are not a current member of the service the voucher is for, you can redeem your voucher using a PS4 console, PS5 console, web browser, and PlayStation App. If you join PlayStation Plus and still have an active membership when the new PlayStation Plus service launches, you will transition into PlayStation Plus Essential. If you join PlayStation Now and still have an active membership when the new PlayStation Plus service launches, you will automatically migrate to the PlayStation Plus Premium.

If you currently have a PlayStation Plus or PlayStation Now membership, due to changes we are making to the service prior to launch, you won’t be able to redeem a voucher code for that service until your existing membership expires and deactivates, or after the new PlayStation Plus service launches in your area, whichever happens first. Rest assured that your voucher code is still valid. See next question for further information.
If you do not have an active membership, the PlayStation Plus voucher you redeem will provide you access to PlayStation Plus Essential for the length of time denoted on your original voucher. For example, a one-month PlayStation Plus voucher will provide access to one month of PlayStation Plus Essential.

The PlayStation Now voucher you redeem will provide you access to PlayStation Plus Premium for the length of time equivalent to the monetary value of your original voucher. Please check the conversion chart below for details.

If you are an existing customer, the PlayStation Plus or PlayStation Now voucher you redeem will be converted to a length of time on your current PlayStation Plus membership plan equivalent to the monetary value of the voucher you are redeeming. Please check the conversion chart below for details.
PlayStation Store voucher codes contain twelve digits. If you have a ten-digit discount code, please see How to redeem a Discount Code.

The voucher code must be for the same region as your account. If you have a physical card, look for a printed flag indicating its country.

In order to redeem some subscription vouchers you may need a valid payment method on the account.

PlayStation®Plus trial vouchers can only be redeemed on accounts which have not previously subscribed to PlayStation Plus.

It is not possible to transfer funds or content between accounts, so make sure to redeem your code on the correct account.
You can only use a voucher code once. To check the transaction history of your account, sign in to Account Management online. If already used, the voucher code will appear in the transaction details section.
