Getting your Handicap Index is easy as 1-2-3

1 - Sign up for a GHIN Number

GHIN—Golf Handicap and Information Network, pronounced “jin”—is a handicapping computational service provided by the USGA through authorized associations and clubs. A golfer must belong to a golf club to obtain a USGA Handicap Index after which they will get a GHIN Number.

Your unique GHIN number lets you post scores from which your Handicap Index is calculated.

  • You can get a GHIN number by joining a golf “club” such as the men’s or women’s club at a local golf course, or one at your workplace or community. Join
  • Don’t want to join a club? Find an Associate Club through WA Golf.  Members receive a GHIN number with their online club membership.

2 - Start posting your scores

Once you have your GHIN number you can post your scores in one of three ways:

  • At the golf course posting terminal after your round is played
  • Online at or at
  • Through the USGA GHIN app on your mobile device. The app lets you post your scores, calculate course handicap, view score history and more.

We recommend posting your scores as soon as possible after your round was played.

3 - Post five 18-hole rounds*

A minimum of five 18-hole or 10 nine-hole scores posted are all that’s needed to calculate and establish your Handicap Index! The more you post your scores, the more accurate your handicap.

* In January 2020 we will be switching over to the World Handicap System. For more information on the World Handicap System and how it will affect your current handicap, please visit
