Many people searching for 355 E Plumb Ln Reno NV 89502 extended ZIP code are trying to ensure their mail arrives quickly, avoid delivery errors, or complete official paperwork (like taxes, business registrations, or utility setups).

In this guide, we’ll walk you through everything you need to know about the extended ZIP code for this specific Reno address, why it matters, and how to find it reliably.

What Is an Extended ZIP Code (ZIP+4)?

Before diving into the specific code for 355 E Plumb Ln, let’s clarify what a ZIP+4 actually is.

The standard U.S. ZIP code (like 89502) identifies a general delivery area—usually a neighborhood or small town. The extended ZIP code, also known as ZIP+4, adds four extra digits after a hyphen (e.g., 89502-1234). These four digits narrow your location down to a specific segment: a city block, a group of apartments, a single high-volume receiver (like a university or business), or even a single building.

According to the United States Postal Service (USPS), using ZIP+4 codes can:

• Improve mail sorting accuracy by up to 30%
• Reduce delivery time by 1–2 days
• Lower the risk of misdelivered or returned mail

This is especially important in dense urban zones or commercial districts—like parts of Reno near Plumb Lane.

💡 Pro Tip: ZIP+4 codes aren’t static. They can change if mail volume shifts or USPS reorganizes delivery routes. Always verify before use.
