Quick answer: Do not redeem a Steam code just to test it. Confirm the printed value, region, currency and original purchase record, then match those details in Kardora’s quote flow before selling.

Do not confuse a Steam code with Steam Wallet balance
An unused Steam gift card contains a code that can add funds to a Steam account. A Steam Wallet balance is the amount already stored inside an account after redemption or other funding. Steam's official support says a signed-in user can see the current Wallet balance in the top-right area of Steam.
If you want to sell an unused Steam gift card, do not redeem it simply to make the value appear in your Wallet. Once the value enters an account, it is no longer an unused gift card code.
Verify the card details before selling
Use the card, receipt or original digital delivery record to confirm:
- physical Steam card or digital code;
- issuing country and currency;
- exact denomination;
- whether the protective area has been scratched;
- whether the code has been shared or redeemed;
- whether the purchase receipt is available.
Steam cards from different regions and currencies are not identical. Match the actual card instead of assuming every card with gaming artwork has the same market or estimate.
What the official Steam balance shows
Steam's purchasing and billing FAQ explains how to view funds already stored in a Steam Wallet. That account balance does not confirm that a separate unredeemed card still contains value.
For an unredeemed card, retain the original code and purchase proof. Avoid websites that promise to test a code by asking you to submit it. A valid code can be redeemed by anyone who obtains it. Steam also warns users not to give wallet gift cards to unknown people.
Check the correct rate on Kardora
Open Kardora's current quote flow, select Steam and match the region, currency, format and value. The Steam gift card rate guide explains why those details affect the NGN estimate.
Do not choose a different Steam region because its displayed rate is higher. Validation checks the submitted card, and a mismatch can make the estimate inapplicable.
Before you submit
- Confirm that you still possess an unused card or code.
- Identify country, currency, format and value.
- Keep the receipt or digital delivery record.
- Protect the full Steam code from public messages.
- Select matching details in Kardora.
- Follow the requested photo or e-code proof instructions.

Frequently asked questions
Can Steam show the balance of an unredeemed gift card?
Steam displays the Wallet balance already held in a signed-in account. Do not redeem a code just to test it when you plan to sell the unused card. Use the printed value and original purchase evidence.
Can I sell funds already added to my Steam Wallet?
Steam Wallet funds are different from an unredeemed gift card. Submit only supported unused card formats shown by Kardora, not an account balance.
What if the Steam code has been scratched?
A revealed code must be protected carefully. Do not post its photo publicly or send it to several buyers. Provide it only through the official secure submission process.
