Use Zip Code Title For Free

The correct way to address letters and packages in the United States is "City, State ZIP code". This format ensures that the letter or package is delivered to the correct location. In this example, "New York" is the city, "NY" is the state abbreviation, and "10001" is the ZIP code.

The most complete ZIP Code is a nine-digit number consisting of five digits, a hyphen, and four digits, which the USPS describes by its trademark ZIP+4. The correct format for a numeric ZIP+4 code is five digits, a hyphen, and four digits.

Place the city, state, and ZIP Code in that order on the last line. This must be the last line. Never place an ?attention line,? telephone number, or other entries after the ZIP Code line.

Leave one space between the city and state and two spaces between the state and ZIP Code?. Use black ink on white or light-colored paper. Use a PO Box? address or street address?but not both.

Write the mailing address of the recipient, starting with the street and city on the third line, and state and zip code on the fourth line. If the recipient is in another country, indicate the name of the country in the fourth line.

If you want to improve the chances that the letter will make it to its destination quickly, you should use the five-digit ZIP code plus the four additional numbers that are specific to the area. To format, write the ZIP code with a hyphen afterward and then the four additional numbers will immediately follow that.

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.
