How many rounds do you need to play to obtain a Handicap Index?

The Rules of Handicapping require that, before obtaining an official WHS Handicap Index (Initial Handicap Index), the following be played and posted:

• one 18-hole or 9-hole round in EGA member countries
• three 18-hole rounds or six 9-hole rounds in other countries

Outside EGA member countries, a combination of 18-hole and 9-hole rounds is also permitted, for a total of 54 holes.
