How postal codes work in Bangladesh
Bangladesh uses a 4-digit postal code system administered by Bangladesh Post Office. The first digit broadly identifies the region, narrowing down through district and upazila to a specific post office or delivery area. Codes range from 1000 (Dhaka GPO) up through the seven divisions covered in this directory.
