What the Error Means
"Key has already been redeemed" or "This code has already been used" is the message Epic Games displays when the system identifies the code as already activated. The problem can originate from the seller's side or from Epic's side.
Root Causes
1. The Code Was Genuinely Already Used The most common cause: the code was resold (fraud by a dishonest seller), or you already activated it in the past and forgot.
2. Epic Database Error Sometimes a code is marked as used due to a technical glitch during a previous activation attempt, even though the V-Bucks or item were never actually credited.
3. Typo When Entering the Code Similar characters (O and 0, I and 1, l and 1) are easy to confuse. An incorrect code could coincidentally match a different code that was already used.
4. Regional Restrictions Some codes are tied to a specific region. Trying to activate them in a different region may produce this same error instead of a regional restriction message.
Step-by-Step Resolution
- Check if you already activated the code. Go to epicgames.com → Account → Transactions. Look for a V-Bucks credit or the corresponding item. If it's there — the code was activated on this account.
- Double-check the code character by character. Re-enter the code carefully, avoiding autocorrect and character confusion. Best to copy it directly from the original email or PDF.
- Check your account's region. If the code is meant for a specific region (e.g., Argentina), confirm your Epic account matches that region, or that the code was purchased for global activation.
- Contact the seller. If the code was purchased on Marix or another service — contact their support with your order number and a screenshot of the error. A legitimate seller will check the code status on their end.
- Contact Epic support. At help.epicgames.com, create a ticket with the code (or partial code), a screenshot of the error, and the purchase date. Epic may restore the item if they confirm a technical error.
What to Do If You Were Scammed
If you bought the code from an unverified seller and it turned out to be used — this is a classic fraud scheme. Contact:
- the support team of the platform where the purchase was made;
- your bank to dispute the transaction (chargeback);
- law enforcement if necessary.
Frequently Asked Questions
Can Epic unlock a code that's already been used? Epic won't unlock codes that were legitimately activated. But if the error occurred for a technical reason — they may manually credit V-Bucks upon request.
How long does Epic take to respond to tickets? Usually 24–72 hours. During high-traffic periods (season launches, holidays) it can take up to 5 days.
How do I vet a seller before buying? Buy from authorized resellers or trusted services. Check reviews, how long the shop has been operating, and whether a guarantee is offered.
To avoid this issue entirely, buy V-Bucks and Fortnite gift cards on Marix — only valid codes with an activation guarantee.
