If you are in Canada, use BLS. You don't need PCC from Delhi police. PCC from Indian police stations would lead to a rejection.
This is important. If anyone is reading this and you are in India please apply through PSK for PCC and select the correct category (resident permit afaik). Your local police also gives you a PCC but that is not valid. You need the one from passportindia.gov.in website.
I submitted an application through BLS, but due to an incorrect police station, the verification was not done, and it wasn't clear by the police officer. Right now the status shows " Police Verification Report is not clear and application is under review at Indian Embassy/Consulate.Close"
No idea outside India. I am an outland PNP NOI and I am yet to do PCC as waiting for ITA.
PCCs from police stations are often time/place bound - that has led to rejections here. PSK is safest.
So many have gotten rejections because of PCCs from local police stations. We don't know why that happens, that's why the general advice is to avoid it.
Your PCC should be issued after the date you left India. If your PCC was issued before you left India, it won't work. My answer is also specific to what we see in Express Entry. You'll have to check past cases of PNP or maybe ask under PNP section to get right info.
