PMSSS is a golden opportunity for us and we should not take any risk for it. No doubt there is very less difference in the domicile Pincode and Aadhar Pincode for you and your friends but you have to make sure that both addresses in aadhar and domicile are the same.
The affidavit will take less than 30 mins and cost around 30 Rs only. This will make you safe during document verification.
You also have enough time to make the changes in the domicile till the online application form.
