Can I activate Know by heart in my region?
Most distribution platforms (like Steam) have regional restrictions and different prices for each game: e.g., Know by heart will cost more for customers from United States than from Argentina, but customers from US cannot activate Argentina’s Know by heart key.
We show this regional restrictions information under “Region” in our filters and in the list of Know by heart offers. For instance, “Know by heart Global” means it can be activated in any country, “Know by heart Europe” – only in Europe, and “Know by heart Japan” — in Japan only.
However, some shops do not provide regional information, so the best way to make sure Know by heart will be activated in your region is to visit shop’s product page: there’s always a special block next to the price that shows if it can be activated in your country or not.
What is the difference between Know by heart offers from official stores and keyshops?
Official stores get their Know by heart keys directly from game developers or publishers, while keyshops resell keys from unknown sources.
Keyshops are usually cheaper than official stores, but they are riskier. We recommend reading keyshops’ and sellers’ customer reviews first. Also, most keyshops have buyer’s protection programs to guarantee a refund in case Know by heart key is not working.
