What is the order of acceptance and order of seeding based on?

Order of acceptance is based on ATP/WTA singles ranking, followed by LTA rating at the entry deadline. (Open ranking will be used to determine the order of players with the same rating). Seeding in all draws is based on ATP/WTA singles ranking, followed by LTA rating (and then Open ranking) at the time of making the qualifying draw (7 day rank). Wherever feasible (after ATP/WTA singles ranking), each draw is composed of players in ratings groups.
