Can I activate Portal in my region?
Most distribution platforms (like Steam) have regional restrictions and different prices for each game: e.g., Portal will cost more for customers from United States than from Argentina, but customers from US cannot activate Argentina’s Portal key.
We show this regional restrictions information under “Region” in our filters and in the list of Portal offers. For instance, “Portal Global” means it can be activated in any country, “Portal Europe” – only in Europe, and “Portal Japan” — in Japan only.
However, some shops do not provide regional information, so the best way to make sure Portal 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 Portal offers from official stores and keyshops?
Official stores get their Portal 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 Portal key is not working.
