What does mail stop mean in an address

In an address, "Mail Stop" (also abbreviated as "MS" or "M/S") is a designation used to identify a specific location or department within a large building, complex, or organization. It's not a physical street address, but rather a way to direct mail and packages to a specific area or individual within a larger facility.

When you see "Mail Stop" in an address, it usually means that the recipient is located in a specific department, floor, or wing within a larger building. For example:

• "123 Main St, Mail Stop 101" might indicate that the recipient is located in the 101st department or office on the main floor of a building at 123 Main St.
• "456 Corporate Dr, Mail Stop 3rd Floor" might indicate that the recipient is located on the 3rd floor of a building at 456 Corporate Dr.

Mail Stops are commonly used in large organizations, such as:

• Corporate offices
• Hospitals
• Universities
• Government buildings
• Military bases
• Large commercial buildings

When sending mail or packages to an address with a Mail Stop, it's essential to include the correct Mail Stop designation to ensure that the item is delivered to the intended recipient.
