The use of the postal code map is becoming more popular as large companies and governmental agencies recognize the benefit of having a unique identifier for all of the cities in the world. Postal codes are used on a global basis with scanners in centralized postal stations that sort and distribute millions of letters, parcels and packages each day. The system of scanning posts is so efficient that the percentage of mail that is mishandled is minimal.

Many of the scanners used in centralized postal stations are designed to read bar codes that contain postal codes. Bar codes containing relevant data from the maps are affixed to envelopes and parcels and quickly distributed using the scanning machine.

Many of these scanners also are equipped to read handwritten letters and numbers on a parcel. When the letter goes through the scanning machine it translates the handwritten numbers and letters into codes that then transfer the letter to the appropriate distribution bin.

Postal stations are located in small towns and cities throughout the world. Postal employees collect and distribute mail in these small stations which are then collected by centralized postal collection teams. The centralized stations are located in large cities and often near airports.

The machines that are used in centralized stations are very large. They receive mail via a conveyor belt that narrows to a width that forces the letter under the scanner. When the letter has been scanned it is automatically transferred by conveyor belt to bins that are sent to distribution points locally, nationally, or internationally. When a department must manually sort mail that cannot be read by the scanner, the postal operator scans the handwritten numbers and letters. The data is then transferred to the main system which allows the scanning machine to read numbers and letters of that shape automatically when they are sent through the system again.

Inserting the wrong postal code can cause a letter to go awry. The letter or parcel may wind up in a foreign country and not be returned to the sender for several years. This is not the case when no number is put on the parcel. In that case a postal officer puts the proper postal code on the letter using information collected from the postal code map.

All scanning machines are connected using a global postal map that is contained in the hard drive of each machine. The data is regularly updated and is continually being improved to make the system more efficient. In some cases, the scanners are set to read the number closed to that shown on the postal map. When this number is incorrect, the letter can be lost.

When you need a postal code it is very easy to get the postal code map for your local area or region. Many people find that they are able to access a database of postal codes through websites that focus on the codes in different countries or regions.

Large companies are finding that using postal code maps as part of the electronic systems for tracking clients is cost effective and efficient. The codes assigned to each country, region, and city in the world are unique and make it very easy for large companies to electronically organize and store client records easily.
