About 1,500 products will be developed and sold, featuring Birmingham 2022, Commonwealth Sport and Home Nations branding.
A first phase of merchandise, including hoodies and t-shirts, mugs, water bottles and pin badges will go on sale online in the next couple of months.
It comes after Cube Intenational was appointed to design and licence products.
Cube International will also create exclusive ranges for the Birmingham 2022 official mascot, which will be unveiled later this year.
About 35 official retail stores will be set up, including a Birmingham city centre megastore, and at a number of other city centre locations, transport hubs, Games venues and temporary live sites.
The retail stores will employ around 300 people.
In addition to these official retail stores, other local and national retailers are being encouraged to register their interest in selling products.
