The Porsche Club of America (PCA) is the largest single marque car club in the world. It is a volunteer-led, non-profit organization with 147 local regions covering the USA and Canada. The regions are grouped into 14 Zones. Members join the PCA but are affiliated to the local region in which they live. This enables them to participate locally in their own region’s events and activities. As a PCA member, they are welcome to attend any PCA events whether nationally organized – such as Porsche Parade, Treffen, etc. – or run by any Zone or region on the continent. Zone 1 includes 17 PCA regions in the North East USA and Eastern Canada.
