The ZIP code system is more than 50 years old, but it is used nowadays as an efficient method to facilitate the work of postal service officers. Zoning Improvement Plan was introduced in 1963 and has been used until nowadays. Do you know by the way, that initially, this code consisted of two number only? One was used to determine a city, and the other one was applied to determine a state.

However, with time, it was evident that just two numbers are not enough to make the USA postal service efficient enough. So, further, more numbers were added to determine the postal facility, the local zone, and even, in some cases, a specific location.

Many people still believe that a postal code and a ZIP code are the same phenomena. However, it is not correct. A postal code is a code that is assigned to a particular location. In this case, you can identify the location based on the postal code. While the ZIP system is a system applied to postal codes, not geographical locations. That’s why it might look weird to usual people.

And that’s why if you don’t know a particular code, you will not be able to figure it out on your own. You might need either to use additional information sources or to request this data in the nearest post-office.

Some tools offer a reverse search. You provide the code, and they will inform you about the full address to which the code was assigned. The main disadvantage of such tools is that not all countries are available. For example, if you need to send a letter or a postcard to an African or an Asian country, you, most likely, will not find any data about these numbers.

Please also note one important fact: not all countries use this system, in some, just postal codes are applied. Well, what we are talking about: in some countries, people still live in tribes and don’t have actual addresses. So, the information that you get from the internet is good, but it is always more reliable to verify it in a local post office. Only then you can be confident that the provided data is correct and your letter will find the recipient.
