There are many alumni chapters in India and around the world. Those in India include Delhi, Mumbai, Kolkata, Chennai, Bangalore, Hyderabad, Jaipur, Indore, Noida, Gurgaon, J&K, Gujarat, Punjab and, of course, Dehradun.

Overseas chapters include the US, UK, Singapore, Hong Kong, Dubai, Australia, Nepal, Pakistan, South Africa, and UAE.

The chapters meet regularly for social occasions, large and small, and to welcome newcomers to their geographical region. This includes boys who have just left the school and who have arrived to start their university studies, either at undergraduate or postgraduate level.

They receive a copy of the Old Boys Directory which gives them the contact details for each region.
