Many observers, recipients, or even businesses may find mail-stop codes incomprehensible, but employees at the facility can decipher and comprehend the information, including details about the address, the floor, and even the department or desk where the mail must be sent.

The facility uses stop codes for both internal mail and mail received at the organization. In the United States, when sending mail to a mail stop facility, state the recipient's name, the recipient's mail stop code, the department and facility names followed by the street address and city, state, and ZIP code.

ZIP codes separate mail delivery areas within a city. Each of these smaller areas is divided into a set of mail stops. For example, the ZIP code 33004 can have different post offices such as 33004-0001, 0002, and so on.
