Let's say you live in Villupuram both Trichy and Chennai have passport offices. Geographically, Villupuram is equidistant from Chennai and Trichy. Does that mean you can apply for your passport either from Chennai or Trichy?
No. You can't.
So, how are you supposed to know which passport office to choose from the drop down list?
1. Click here to go to the 'Passport Seva Kendra or Laghu Kendra' page. Aternately, it's the 4th link under 'Information Corner' to the left of the user login page. When you land there, this is what you'll see.
Of what use is the PSK address I've boxed in green? You'll have to choose one these addresses when you schedule your passport interview.
