When it comes to building franchise territories, precision is everything. Whether you’re defining exclusive rights, setting marketing boundaries, or mapping a franchise territory, having an accurate list of ZIP codes for your target city is the foundation of everything that follows.
But here’s the catch: not all ZIP code lists are created equal. Many online sources are outdated, incomplete, or flat-out wrong—and ZIP codes change more often than you might think, with new ones added or adjusted regularly to keep up with shifting population and delivery demands.
✅ The good news? The U.S. Postal Service (USPS) offers the most up-to-date, official ZIP code lookup tool—and it’s completely free.
✅ Even better? Zors makes it easy to turn that list into a clean, professional territory map with just a few clicks.
In this article, we’ll show you:

Let’s dig in.👇
The U.S. Postal Service maintains the official list of every active ZIP code nationwide. By using their free lookup tool, you tap directly into the source for the most current data.
Open the USPS Lookup Tool
Go to https://tools.usps.com/zip-code-lookup.htm and select “Find by City & State.”
Click "Find By City & State"
Enter Your Location
City: Virginia Beach
State: Virginia
Hit “Search”
You’ll see a list like:
VIRGINIA BEACH VA 23450
This ZIP Code™ used for a specific PO BOX
VIRGINIA BEACH VA 23451
VIRGINIA BEACH VA 23452
VIRGINIA BEACH VA 23453
VIRGINIA BEACH VA 23454

💡 Tip: Double‑check for any “unique” ZIPs (e.g., PO Boxes) you may or may not want included
Chatbots and Search Engines: Search results often pull from static blog posts, cached content, or third-party lists that haven’t been updated in months—or even years. Models don't connect directly to USPS.
Web Scrapers & APIs: Often miss recent changes—some ZIP codes might be retired or newly created.
Third‑Party Databases: Licensing delays mean data can be weeks or months old.
Manual Lists on Blogs: Static articles rarely get updated, so relying on them is risky.
Need to verify whether a particular address falls within your target city or county? The USPS ZIP Code Lookup tool can help with that too.
Instead of searching by city, use the "Find by Address" tab. Just enter a full street address, and once the result appears, click the downward expanding arrow icon (▼) to see additional info like:
City name recognized by USPS
County name
Delivery point details
🧭 Why this matters:
When territory boundaries depend on municipal or county lines—or when certain areas use one city name for mailing but are governed by another—this extra detail helps you stay precise and map accurate territories with the rights franchisees want.
✅ Perfect for checking edge cases, verifying franchisee locations, or resolving city/county overlaps.
