How many digits are contained in the ZIP+4?

The correct answer is: 9

The ZIP+4 code is an extension of the standard ZIP code used in the United States postal system to provide more detailed information for mail delivery. A standard ZIP code consists of 5 digits. The ZIP+4 format adds an additional 4 digits to the standard ZIP code, which helps to designate a more specific address or delivery point. Combining the standard 5 digits with the additional 4, the total number of digits in the ZIP+4 code becomes 9. This specificity assists postal services in sorting and delivering mail more efficiently, particularly in areas with high population densities or large housing complexes. Understanding the structure of the ZIP+4 is crucial for effective mailing processes and addressing.
