You can redeem your Google Play gift card in three ways, all of which can be seen below:
- At play.google.com/redeem: Scratch to reveal the redemption code on the back of the gift card, and enter that code at play.google.com/redeem – funds will automatically be applied to your Google Play balance.
- During the purchase flow: After choosing the digital content you want to buy, during the purchase flow, under Choose a payment method, select Redeem a Google Play Gift Card, and enter the redemption code found under the scratch-off section of your gift card.
- Using the Redeem option on the Google Play Store app on your device: Launch the Google Play Store app, then tap Menu > Redeem, and enter the redemption code from the back of the gift card.
After the credit has been applied to your account, you will be able to use it to purchase applications, games movies, books, music, TV shows and magazines, which can be downloaded directly from the Play Store and stored straight on your Android device.
