Microsoft Rewards Avaiability in Argentina

It's probably down to differences in licensing regulations between the three countries.

Unfortunately that's not an answer we can truly give a direct answer about on the forums, as a good majority of anyone you'll ask on here doesn't have any connection to/ doesn't have the ability to contact the various people needed to answer this question.
As a lot of us are community members and don't work for Microsoft.

The full list of regions where Microsoft Rewards is available is found here: https://support.microsoft.com/en-us/help/4027275/microsoft-account-rewards-regions-and-languages
while they may not support your region now, at some point in the future they may. An ETA on when that is would be unknown as their always working on expanding their programs.

Hello,

We can only recommend authorised Xbox retailers

Microsoft Rewards is a great way to earn points that can be redeemed for gift cards, subscriptions, and competitions/sweepstakes entries. The service is currently supported in Argentina as per the Microsoft Rewards regions

There are also regular promos and contests where you can win or earn Game Pass codes. These are often hosted by brands like Doritos and Monster Energy.

Hope this helps.

Hello epicplaneflyer,

We see that your Xbox Live Account region is currently set to Argentina. Since that country is not a Rewards eligible region, you cannot sign up for the program.

Hello xxxjuanpi18xxx,



I really shouldn't know when it is available for more countries. That's up to Microsoft to make that
decision.

You can find the support countries on
this page.

My suggestion is to check back every 2 months and see if there are more countries added to Xbox Live Rewards.
