Zone Groups

The Zone Groups are divided into three regions: Americas, Asia/Oceania and Europe/Africa. Within each region there are two divisions, Group I being the higher and Group II the lower, except for Europe/Africa Zone, which also has a Group III.

Zone Groups are week-long events played at one location. Each Group is initially split into round-robin pools, with play-offs then deciding promotion and relegation. The exact format of each Group varies according to the number of participating teams.

Ties

World Group and World Group II

Ties are contested in a best-of-five rubbers format and are played over a weekend. There are two singles on Saturday, and then the reverse singles and a doubles on Sunday. The tie is hosted by one of the competing nations.

The host nation is decided depending on where the two competing teams played their most recent tie against each other. If a nation had home advantage last time then it will be away next time, and vice versa. If the nations have never previously met, or if they faced each other at a neutral venue, then the choice of ground is decided by lot.

Zone Groups

Ties are contested in a best-of-three rubbers format and are played on one day. There are two singles followed by a doubles. Due to the multi-nation format, ties take place on successive days.
