Understanding ZIP Code Prefixes (0-9)
The first digit of a US ZIP code represents a specific geographic region.
Understanding Geographic Coordinates
Geographic coordinates are a set of numbers (Latitude & Longitude) used to specify a precise location on Earth. When you use our ZIP Code Lookup, we provide the Centroid Coordinates—the exact mathematical center point of that ZIP code's boundary.
Latitude (Lat)
Latitude measures distance North or South of the Equator (0°). Think of it like a ladder:
- Positive Numbers (+) represent the Northern Hemisphere (USA, Europe, Asia).
- Negative Numbers (-) represent the Southern Hemisphere (Australia, South America).
The higher the number, the further North you are.
Longitude (Lng)
Longitude measures distance East or West of the Prime Meridian (0°) in Greenwich, UK.
- Positive Numbers (+) represent the Eastern Hemisphere (Europe, Asia, Australia).
- Negative Numbers (-) represent the Western Hemisphere (North & South America).
The "more negative" the number, the further West you are.
34.0522 instead of traditional Degrees/Minutes/Seconds (DMS) because it is machine-readable. This allows applications like Uber, Google Maps, and Weather apps to calculate precise distances instantly.

How "Jack" Avoided a Costly Shipping Error
Meet Jack, an eBay seller from Ohio. He received an order with a confusing address: "123 Maple St, Beverly Hills, FL, 90210".
The Problem
Jack knows 90210 is famous for California, but the customer wrote "Florida" (FL). If he ships it blindly, the package gets lost or returned.

Jack typed 90210 into our tool. The result confirmed: Beverly Hills, CA. He contacted the buyer, corrected the state to "CA," and the package arrived on time.
Alert: User entered "FL" but ZIP belongs to "CA".
