1. Understanding Orange County's Postal System

Orange County, like other regions in the United States, uses a five-digit postal code system to streamline mail delivery. Sometimes, you'll see a postal code followed by a hyphen and four more digits; this is the postal code plus four, or ZIP+4 code, which helps further narrow down the location to a specific block, building, or even side of the street.

The postal codes are generally arranged geographically, though there can be exceptions due to historical reasons or local postal service considerations. The lower postal codes tend to be in the northern parts of the county, gradually increasing as you move south. — Is Netflix Down? How To Check & Troubleshoot
