It's the worst portal ever. First, if you select residence address you still have to fill office address and I do not live in India. I filled my Qatar address and it's automatically showing ******* in pincode which is not getting changed on clicking and qatar does not have a ZIP code. In the end, I had to fill in my India residential address. I put my international number but never received an OTP on it. They do not accept international cards. After I finished the payment, the portal asked for an OTP which I had been waiting for 30 minutes. I never received it on my email ID or phone after requesting it twice and still waiting. It's better to apply manually than to apply online. There is no point.
