Pin code not needed: Instead of using the pin code, a district-wise search on the CoWIN portal can increase the chances of getting the slot. If the GPS is turned on, the nearby centres will be shown on the map. But it is better to check the entire district.

Paid/free: While booking, use filters such as Paid, Free, Age 18+, Age 45+ and so on to better locate the hospitals. Private hospitals can be located quickly if the paid option is selected.
