What is US Postcode or US Zipcode:

ZIPCODE - Zone Improvement Plan Code is an addressing system used to quickly assign and better allocate addresses for easy access. Mail sent using Zipcodes travels much more better and quickly (i.e, zipping along) when senders make use of the code in the postal address. The term ZIP Code was originally registered as a service trademark by the USPS, but the registration expired in 1997.

In 1983, the U.S. Postal Service introduced an expanded ZIP Code system that it called ZIP+4, often called "plus-four codes", "add-on codes", or "add-ons". A ZIP+4 Code makes use of the basic five-digit code plus four extra digits to identify a geographic segment that is within the five-digit delivery area, such as a group of apartments, a city block, an individual high-volume receiver of mail, a post office box, or any other unit that could use an extra identifier to aid in efficient mail sorting and delivery.

For Post Office Boxes, the general (but not invariable) rule is that each post office box would have its own ZIP+4 code. The add-on code is mostly made up of one of the following: the last four digits of the box number, zero plus the last three digits of the box number, or, if the box number is made up of lessr than four digits, enough zeros are attached to the front of the box number to bring up a four-digit number. However, there is no uniform rule, so the ZIP+4 Code must be looked up individually for each of the box.


How Can I Find My Postcode or Zipcode in USA?

There are four types of US ZIP Codes and they are:
1. Unique: assigned to a single high-volume address
2. Post Office Box-only: used only for PO Boxes at a given facility, not for any other type of delivery
3. Military: This type of Zip Code is used to route mail for the U.S. military
4. Standard: all other ZIP Codes.

ZIP Codes are numbered with its first digit denoting a certain group of U.S. states, the second and third digits together representing a region in that particular group (or maybe a large city) and the fourth and fifth digits denoting a group of delivery addresses that are within that region.
