World Handicap System Is Live. The initiative to unify the six different handicap systems in use around the world into a single World Handicap System on Jan 1, 2020. Now, all handicap service providers (e.g., GHIN, GolfNet, etc) use the same calculation method and the same course rating database. Chapter members wishing to open or renew a Handicap Index account are offered two options:
1. Your 2020 LPGA Ams membership includes a complimentary handicap account, offered  through Golfnet.
2. Or, you may elect to use GHIN for an annual fee of $37.
