Address mail with 5 or 9 digit zip code

In the United States, the standard ZIP code is a 5-digit code that is used to identify a specific geographic area. However, there are also ZIP+4 codes, which are 9-digit codes that provide more precise geographic targeting.

Here's how to address mail with a 5-digit ZIP code:

Format:

[Recipient's Name] [Street Address or PO Box] [City, State ZIP Code]

Example:

John Doe 123 Main Street Anytown, CA 12345

And here's how to address mail with a 9-digit ZIP+4 code:

Format:

[Recipient's Name] [Street Address or PO Box] [City, State ZIP+4 Code]

Example:

John Doe 123 Main Street Anytown, CA 12345-6789

Note that the ZIP+4 code is optional, but it can help improve delivery accuracy and speed. The extra 4 digits provide more precise geographic targeting, which can be especially useful for businesses or organizations that receive a high volume of mail.

It's worth noting that the USPS recommends using the ZIP+4 code when possible, as it can help reduce errors and improve delivery times. However, if you're unsure whether to use a 5-digit or 9-digit ZIP code, you can always check with the USPS website or consult with a postal service representative for guidance.
