Cincinnati, OH ZIP Codes: Find Your Local Area

Navigating Cincinnati, Ohio, often starts with understanding its ZIP codes. Whether you're sending mail, relocating, or simply curious about a specific neighborhood, knowing the correct ZIP code is crucial for efficient delivery and local identification. This guide provides a comprehensive overview of Cincinnati's ZIP codes, helping you pinpoint any area within the city and its surrounding communities.

What is a ZIP Code?

A ZIP (Zone Improvement Plan) code is a postal code system used by the United States Postal Service (USPS). It consists of a five-digit number that identifies a specific geographic area for mail sorting and delivery. An optional four-digit add-on, known as a ZIP+4, further refines the location, often specifying a particular street or even a building.

The History and Purpose of ZIP Codes

Introduced in 1963, the ZIP code system was designed to streamline the mail sorting process, making it faster and more efficient. Before ZIP codes, the postal service relied on more cumbersome methods, leading to delays. By assigning a unique numerical code to every delivery route and post office, the USPS significantly improved delivery times and accuracy.
