Redemption code questions (do redemption codes add time to existing subscription, multiple codes)

[Dean22397660z4uh]

I have the following scenario: 

• I currently have an active Photography plan (20GB) 12-month subscription. This subscription was from redeeming a code I bought from an authorized 3rd party (Newegg). I activated this subscription on January 9, 2023. It expires on January 8, 2024. 
• I recently purchased another Photography plan (20GB), 12-month — same subscription product — from another authorized 3rd party (Dell). 

Here are my questions: 

1. What happens when I try to redeem the second code from Dell? Will it (A) create a new Photography plan subscription that runs parallel to my current one? Or will it (B) add 1 year to my existing plan, such that my new Photography plan expiration is January 8, 2025 (instead of January 8, 2024)?

2. If (B) to question #1 above is correct, is there a limit as to how many redemption codes I can redeem? For example, if I buy 2 more 1-year redemption codes and redeem to my account, can I add them to my account now and extend my expiration date another 2 years?

3. If (A) to question #1 is correct, is there a time limit as to how long a code is valid for? i.e., if I need to wait for my existing subscription to expire, how long can I "sit on" an unredeemed code, and will it become invalid after X months, even if it has not been used?

I've both called and chatted with Adobe support, but I am getting conflicting answers. Some agents say that redeeming the code creates a parallel subscription, while other agents say that it adds additional time to the existing subscription. I've also read this help article, and it seems to suggest (B) to question #1 is correct (assuming I am redeeming the same product in the same Adobe account), but given the conflicting answers from support, I'd like to check.

if you sign in with the same adobe id as your current subscription and then redeem your code, the additional time will piggy-back to your current subscription and extend it.

Dean, thanks for your question. Using Redemption codes can be tricky. The method Kglad described works when both plans purchased are identical. You should be ok with the scenario above. Still, there is the possibility a different reseller will be offering a redemption code for a slightly different service, which could then lead to duplicate but near identical memberships being created.

If you keep purchasing the redemption code from the same reseller, there is a good chance they will still offer the same plan a year later. If you use a different reseller, the risk is mentioned above. If you need any assistance or end up creating a duplicate membership while completing the steps listed in https://helpx.adobe.com/download-install/kb/redemption-code-help.html then please don't hesitate to click on https://helpx.adobe.com/contact.html?rghtup=autoOpen to begin a secure chat session so a member of our support team can help you.

For future viewers of this discussion, I would encourage you to purchase your plan directly from https://www.adobe.com/ if it is available within your country. The additional account management options listed in https://helpx.adobe.com/manage-account.html are available to individuals who buy through the Adobe online store. 

You should also avoid purchasing multiple redemption codes simultaneously and stacking them on the same account, as it could lead to the membership being invalidated or flagged for possible fraud.
