Ward vs PIN address form fixer
PIN, ward, and zone are three different systems. Walk the decision tree before you fight a dropdown — then confirm with live civic lookups.

FAQ
Why does my PIN map to the wrong ward in an app?
Most apps approximate PIN centroids. Chennai PINs are not ward polygons. Use GCC ward lookup (or our Zone & Ward Finder) for Corporation fields, and India Post for postal fields.
Is zone the same as assembly constituency?
No. GCC zone is a municipal administration layer. Assembly constituency and Lok Sabha seats are electoral layers with different boundaries.
My school / bank form only has a zone dropdown from years ago
Ask the institution which map year they use. If they cannot say, enter locality + PIN accurately and attach a note with your current GCC ward from an official or verified lookup.
Does a zone change automatically change property tax?
Not by itself. Tax follows assessment rules on the GCC revenue portal. Zone/ward labels help route files; they are not a tax calculator.
