OSP Registration in India: A Guide for Call Centers, BPOs & IT-Enabled Services

5 min readAugust 10, 2026

Call center operations representing OSP registration requirements in India

OSP (Other Service Provider) registration is one of the more commonly misunderstood requirements in Indian telecom regulation -- not because it's complicated, but because most businesses that need it don't think of themselves as a "telecom" company at all.

What OSP registration actually covers

OSP registration applies to companies that use telecom resources to provide a service that isn't telecom itself -- call centers, BPOs, IT-enabled services, tele-banking, tele-medicine, and similar. If your business runs a call center or uses telecom infrastructure to deliver outsourced services, OSP registration is very likely relevant to you even though you're not selling connectivity to anyone.

It got a lot simpler in 2019

DoT significantly reformed OSP registration in November 2019: bank guarantee requirements were removed entirely, the separate domestic and international OSP registrations were merged into one simplified registration, and much of the ongoing reporting burden was reduced. If you looked into OSP registration before 2019 and found it burdensome, it's worth another look -- the current process is considerably lighter than it used to be, though it's still a mandatory registration, not optional.

Who needs to register

  • Call centers and BPOs handling voice traffic
  • IT-enabled services companies using telecom connectivity as part of service delivery
  • Tele-banking and tele-medicine providers
  • Any business whose service delivery model depends on telecom resources, even if telecom isn't the product itself

Where to go from here

OSP registration sits outside Infinity Consultants' core focus, which is VNO, ISP, and PM-WANI licensing specifically. If OSP registration is what you need, we can point you toward the right resource for it. If your business is actually looking to become an ISP or VNO -- selling connectivity rather than using it to deliver another service -- that's exactly what we handle end to end.
