how many rewards points do you need for a free gamertag change?

ok ballpark figure about 10K.

Depends on the region you're in and the amount of tax you'd have to pay really. Based on US currency, you'd need at least 10,000 for the change, plus another 2,000 or so (at most) for tax.

Hi there,

Gamertag changes cost $10 (US), but is dependent on what region you are in.

If you're asking how many Microsoft Reward (formerly Bing Reward) points need to be earned and then redeemed for a gift card within the program to then purchase the change, you're looking at 9,300-10,000 currently in the US (depending on what level you are
at within the Microsoft Rewards program).

With Microsoft Rewards points, once you earn enough points you can redeem an Xbox gift card to add funds to your account and then use those funds to purchase a gamertag change. The support person you spoke to was misinformed on how many points it takes.
Prior to the currency system Microsoft used points as currency and at that time it cost 800 Microsoft points to change a tag. Microsoft points are not the same as Microsoft Rewards points though so you would need enough points to redeem a $10 gift card as
well as a little extra to cover tax.

you would need to post on the rewards forums but do note that the rewards system is changing

anyone with pending points are having them issue to the gamertag as the points will be phrased out when the new dashboard update gets released.
