How to Redeem Gift Card Codes: Apple / Google Play / Steam Guide
Redemption entries per platform, region-matching rules, and troubleshooting for redemption failures, plus region tips before buying.

Nine out of ten redemption failures come from region mismatch. Confirm the code region matches your account region before redeeming; that is also the only rule when choosing a region at purchase.
Apple gift cards
In the App Store, tap your avatar and choose Redeem Gift Card or Code. The code region must match your Apple ID region; US cards need a US Apple ID.
Google Play gift cards
Choose Redeem code in the Play Store menu. Some countries also check the IP location; use a US IP when redeeming US cards.
Steam wallet codes
Redeem under Add Funds in the Steam client. Wallet codes are currency-specific and credited at the day’s rate; cross-region use risks a red lock, so always match your account currency.
Troubleshooting checklist
Check in order: typos (0/O, 1/I), account region, abnormal IP, and whether the code was already used. If it still fails, contact support with the order ID and a screenshot for a replacement.
