Please see Destiny 2 PC Region Definitions for regional information on Destiny 2.
We provide keys for all of the regions mentioned within this link, however, you will only receive a key for the regional location you are purchasing from. Using a VPN to make purchases on our site will result in the incorrect regional key being provided.
Please also ensure that your Blizzard account's "Country of Residence" matches your current location. You will not be able to redeem your Destiny 2 key if they are not the same. Please contact Blizzard support if you find that your Country of Residence is incorrect.
