The Millers have started selling tickets from the towns visitor center on Bridgegate.
The office is open from 9:30am to 5pm Monday to Saturday.
Community Liason officer Mark Hitchens told the clubs official site; "This is a big move for Rotherham United; we feel that this will give the supporters who might find it difficult to get to Mangham House the option of gaining tickets from the town centre."
"What we need now is the fans to get behind us; we also need the businesses of Rotherham to back us in our quest to move back into Rotherham and into a new stadium. We are now going to be in the media spotlight so it is a massive opportunity for any company to get some good positive advertising." he added.
