Genshin Impact codes give free Primogems and materials, but they expire fast. Here is how to claim them without wasting a code.
Check you are Adventure Rank 10
You must reach Adventure Rank 10 before the game lets you redeem a code. Do this first.
Redeem on the official page
Open genshin.hoyoverse.com/en/gift, sign in with your HoYoverse account, pick your server and enter the code. This is the fastest way to clear several codes in a row.
Redeem in the game
Open the Paimon menu, go to Settings, then Account, then Redeem Code. Enter the code and confirm. The reward arrives by in-game mail.
Be quick with livestream codes
The three codes from each Special Program stay valid for about 48 hours. Claim them as soon as they are announced.
Skip expired codes
Check the date on any list. Codes from earlier versions stop working, and some only work on one server.
