Banks, passport offices and job portals also check the code against your address.
For this reason, many online shops reject an order when the code and district do not match.
Likewise, couriers in Dhaka sort parcels by code before they go out for delivery.
So, a correct code saves time for you and for the person who receives the parcel.
