For all those who are wondering about how PCC works:
1) At the time of filing the application, you have to send the PCC for all the districts you live in. If you lived at more than one address in one city for more than 6 months and the other address is in another district where you lived more than 6 months, then you have to send two PCCs.
2) For Re-PCC, you only have to send the PCC for the district you lived in from the time the last PCC was issued(Application submitted). So if you lived in the same district, then you only need to send 1 PCC from that district. If you changed address after applying, then you will have to send two PCC's. One from the old address district and one from the new address district. And if both addresses are in the same district, then its only 1 PCC.
I hope I didn't further confuse you guys.
