ZIP Code Validator
Postal Code Validation
ZIP stands for Zone Improvement Plan and it was introduced for the first time by United States Postal Service in order to increase the speed of delivery. Since then, most of the countries implemented a similar concept.
Usually, a postal code has between 4 and 6 digits, but there are countries that has letters in the postal code.
The idea behind the zip code is to differentiate the cities and streets with the same name. For example, there are many villages with the same name but in different counties, but with a different zip code. So, the zip code can identify exactly the location without knowing the address.
The steps to use this tool are:
- Enter your zip number
- Choose a country
- Click on validate button
