An annual USTA membership is required to play on USTA teams. The cost is $44 for an adult yearly membership and anyone 70+ the fee is $42 for a yearly membership.  For each team a player wants to play on, they must register for that team. The cost of each team registration is $ 22 (plus a $3 administration fee charged by Tennis Link). Some leagues registration fees are less because of the season and flex-play.
