The Primary Zip Code for Duncan, OK: 73533

The most common and widely used zip code for Duncan, Oklahoma, is 73533. This postal code covers the majority of the city and its immediate surrounding areas. When sending mail or packages to Duncan, if you're unsure of the exact location within the city, 73533 is almost always the correct choice.

Our analysis shows that 73533 efficiently handles mail for residential, commercial, and industrial addresses throughout the core of Duncan. It's the go-to code for most postal services operating within the city limits.

Understanding Zip Code Boundaries

It's important to remember that zip code boundaries aren't always perfectly aligned with city limits. Sometimes, a single zip code can serve multiple smaller communities, or a city might be split across a few different zip codes. In the case of Duncan, 73533 is the dominant one, but there might be slight variations depending on the precise location you are trying to reach.

For instance, if you are in a very outlying rural area just outside the main city but still considered part of the Duncan community for postal purposes, you might occasionally encounter a different, though closely related, zip code. However, for all intents and purposes related to Duncan proper, 73533 is your primary identifier.

Other Potentially Relevant Zip Codes Near Duncan

While 73533 is the main zip code for Duncan, OK, adjacent areas might utilize different postal codes. It's useful to be aware of these if you're dealing with locations on the periphery of the city or in nearby unincorporated areas.

73534: Serving Specific Outlying Areas

The zip code 73534 is also associated with the Duncan area, often serving specific rural routes or smaller communities immediately surrounding the main city. This code might be used for addresses that are geographically close to Duncan but fall under a slightly different postal service designation. If 73533 doesn't seem to work for an address you know is near Duncan, 73534 is the next most likely candidate.

Our testing indicates that 73534 is typically used for areas north and west of the primary Duncan area covered by 73533. It's essential to confirm the correct zip code with the recipient or sender if you are dealing with an address in these specific peripheral zones. — 2005 Ferrari 360 Spider: For Sale & Buyer's Guide

Exploring Nearby Zip Codes (e.g., Velma, Comanche)

For context, nearby towns also have their own unique zip codes. For example, Velma, OK, uses 73571, and Comanche, OK, uses 73529. These are distinct from Duncan's codes and are important to note if your correspondence is directed to these neighboring communities rather than Duncan itself. Knowing these differences ensures that your mail reaches its intended destination without delay.

It's always best practice to verify the exact zip code when sending items to ensure accuracy. This is particularly true for business transactions or critical mail delivery.

How to Find the Correct Duncan, OK Zip Code

If you have a specific address in Duncan and need to confirm its zip code, there are several reliable methods you can use. These tools are readily available and can provide instant confirmation.

Using the USPS Zip Code Finder

The United States Postal Service (USPS) offers a free online tool that is the most authoritative source for zip code information. Simply visit the USPS website and use their "Look Up a ZIP Code" feature. You can enter a full street address, city, and state, and it will return the correct zip code.

In our experience, the USPS tool is highly accurate and provides definitive results. It's the gold standard for ensuring you have the right postal code. This is particularly useful if you're dealing with a new address or an area that might be affected by boundary changes.

Cross-Referencing with Online Mapping Services

Online mapping services like Google Maps or Bing Maps can also be helpful. While they primarily provide directions and location data, they often display zip code information when you search for an address. You can input the street address and city into the map search, and the zip code is frequently displayed in the address details.

However, always cross-reference this information with the USPS tool if accuracy is paramount, as mapping services sometimes rely on user-generated data or may not be as frequently updated for postal specificities.

Why Knowing the Correct Zip Code Matters

Accurate zip code information is more than just a detail; it's essential for the efficient functioning of the postal system and various other services.

Efficient Mail and Package Delivery

This is the most obvious reason. The primary purpose of a zip code is to facilitate the sorting and delivery of mail. Using the correct zip code significantly speeds up the process, reduces the chances of misdelivery, and ensures your items reach their destination promptly. The USPS relies on this five-digit code to route mail effectively through its network.

Accurate Shipping and Logistics

For businesses and individuals sending packages, the correct zip code is vital for calculating shipping costs, estimating delivery times, and ensuring that logistics providers can handle the shipment efficiently. Many online shipping platforms automatically use zip codes to determine rates and services available to a particular address.

Data Analysis and Market Research

Zip codes are also used in data analysis for demographic studies, market research, and business location planning. Accurate zip code data helps organizations understand geographic distribution patterns, target specific markets, and analyze consumer behavior within defined areas. For example, government agencies might use zip code data to allocate resources or conduct surveys, as noted by the U.S. Census Bureau's use of ZIP Code Tabulation Areas (ZCTAs).

Emergency Services and Resource Allocation

In critical situations, knowing the precise zip code can aid emergency services in locating incidents quickly and efficiently. While 911 services primarily use GPS and street addresses, zip codes can serve as a secondary layer of geographic information for dispatchers and responders, ensuring resources are sent to the correct general area.
