Large cities were divided into postal zones or postal districts, usually numbered from 1 upwards within each city.

The third digit of a Postal Index Number, which is combined with the first two digits, indicates a specific geographical region or area (except in the functional zone for the Army); it is called a sorting district.

The last two digits indicate the delivery office within the sorting district, which would be the Head Office (HO) or General Post Office (GPO).

A Delivery Office has many services for people like receiving or sending letters, parcels, and boxes to deliver them to their particular destination. A Delivery Office is responsible for providing customer service in very good faith to deliver any mail and items within a short time.

The numbering of the delivery office is done with higher numbers assigned to newer delivery offices. If the mail handled at a delivery office is too large, then a new delivery office is created, and the next available PIN is assigned. The first four digits of the two offices are common.

There are some letters and items that must have stamps on them; otherwise, they will not be able to go for the delivery. On the other hand, some letters don't require postage stamps. The best thing is that the Delivery Office is almost everywhere or near every city, village, and town.

All of them share the same code. The delivery office can be a General Post Office (GPO), or a head office (HO), or a sub-office (SO) which are usually located in urban areas or municipal areas.
