A statement on the Rotherham website said: 'We have been made aware of information concerning the potential for some visiting supporters to purchase tickets in the home end for our play-off semi-final against Preston North End.
'The club have therefore taken advice on ticket sales and will limit tickets to a maximum of five per person. Supporters must also be on our database to purchase tickets or if you are a new registration you will need to provide ID which can be either a passport or driving license.
'If you cannot provide either of the above forms of identification, then two utility bills with your current address on will be acceptable.
'We would like to thank our supporters in advance for their co-operation.'
Meanwhile, Preston Season Ticket holders have until Wednesday to take up their ticket for their seat, before tickets are released for general sale.
