Whether you’re sending a high-value product to a customer or a holiday card to a loved one, you need to use the right address data to make sure the items arrive on time and in the right place.
Postal codes, or zip codes, which are the required characters at the end of addresses, are very important for helping mail carriers figure out where to deliver mail and how to get there.
But if we dig deeper, what is a zip code, what is a postal code, and how are they different? In this essay, we’ll talk about the most important things you should know.
What is a Postal Code?
Whether an item is shipped within a state, across a country, or all the way around the world, these combinations of numbers (and sometimes letters) create a unique identification code that assigns delivery points to a specific place.
It is important to remember that the structure and use of these codes will depend on the exact location to which they are linked. This means that postal codes will probably be different from one country to the next.
No matter how it is set up, the goal of the postal code is always the same: to make mail exchange and delivery more accurate and efficient.
What is Zip Code?
The zip code was created in 1963 by the United States Postal Service® (USPS) to help people distinguish between different post offices across the country.
Mail delivery used to be based on remembering cities and states, but as the country grew and changed, it became necessary to switch to a new method based on numbers.
By 1967, the newly discovered zip code system had been used for all mail processing and delivery in the United States.
Do you want to know more about how to break down this important piece of information? How to figure out a zip code:
- The first digit: this number refers to the national area, or defined group of states.
- The second and third digit: this set of numbers signifies a region within this group, such as a large city.
- The fourth and fifth digit: these numbers represent the associate post office or delivery area of a region.
If you want to send mail within the United States, you need these five numbers. Plus-four codes, on the other hand, are used to make sure that letters are delivered even more accurately. We’ll talk more about these codes below.
ZIP+4 Codes: a look at full zip codes
Most people are familiar with the five-digit zip codes in the list above. But because of the growing need to improve mail sorting and delivery, the system needed more information to keep growing and getting better.
ZIP+4 are the last four numbers at the end of a zip code that are used as an extra way to identify a place.
This makes it possible to pinpoint an address within a few blocks. Overall, these extra numbers help improve the accuracy of letter delivery.
Key Differences Between Zip Code and Postal Code
The difference between a zip code and a postal code can be seen in the following ways:
- A zip code is a postal code that is used with an address in a few countries to show where mail is delivered. The postal code, on the other hand, is the code that is used in the postal address. This code helps sort mail so that it can be sent to the right place.
- The United States Postal Service (USPS) started the zip code system in 1963. The postal code system was started in 1959.
- Most people in the United States and the Philippines know what a “zip code” is. In the rest of the world, on the other hand, the postal code is used.
- Zip codes are used to group areas together to make it easier to sort mail, and they tell where the mail is going. On the other hand, a postal code is used to identify and talk about a place, plan a route, and get information about the people who live there.
- The postal code is made up of numbers or a combination of numbers and letters, and sometimes it also has punctuation. The zip code is only made up of numbers.
