We ship all the products via Delhivery, FedEx and India Speed post. Since Delhivery and FedEx are market leaders when it comes to eCommerce shipping, most of the pin codes are covered by them and deliveries in these pin codes are fast.
However, since they operate only in cities with greater eCommerce penetration, there are a few pin codes which are not serviceable by them on a prepaid or cash-on-delivery service. In such cases, the orders are shipped via India speed post since it covers all the pin codes on the prepaid mode. COD shipments cannot be sent via India speed post.
You can download the entire list of pin codes served by these companies from here.
