I changed my adhaar address from one state to another. Yup, no police verification is done. I got it done in adhaar KYC point and it took 3~4 days iirc.
I posed about this in this same thread iirc few months ago. I went to change address on my adhaar and each adhaar KYC point was only admitting 10 people daily saying servers are down. One persons already had adhaar but his fingerprints weren't getting registered so they casually registered new adhaar in his name taking his biometrics once again. I don't think it checks new fingerprints against fingerprints already available in their database so who knows how many duplicates are there
