Input Zip Code Voucher For Free

A credit card ZIP code is the 5-digit zip code from your U.S. billing address. When you make a purchase, the ZIP code you enter must match the ZIP code associated with your official cardholder address.

So what do the extra numbers mean? These last 4 digits represent specific delivery routes within delivery areas. This extra detail means an even more precise matching to a more granular level. It could represent a handful of houses on one side of a street, or even a single building that receives a high volume of mail.

In 1983, the zip + 4 format we now use (e.g., 60601-1635) was introduced to support delivery to densely populated areas. The first three digits before the hyphen identify the sectional center or large city. The second two classify the post office facility or delivery area.

The USPS provides a free ZIP+4 code lookup tool on their website that can be used to find accurate and up-to-date ZIP+4 codes for specific addresses. By using this tool, individuals and businesses can ensure that their mail is delivered to the correct location in a timely and efficient manner.

Usually what happens is a carrier or post master from the office where the package is sent will correct the zip code by looking at the address and even reach out to that particular post office to ensure the package is delivered to the correct address.

ZIP & ZIP+4 United States ZIP codes are five numerical digits long. ZIP+4 codes, also known as add-on or plus-four codes, include four additional digits that identify a geographic segment within a ZIP code delivery area. The first digit in a ZIP code represents a defined group of U.S. states.

If prompted for your ZIP code, just enter the three digits of your postal code plus two zeros. So for example, if your postal code is A2B 3C4, the 5-digit number you should enter is 23400.
