The Dickinson zip code most commonly refers to 58601, the standard ZIP code for Dickinson, North Dakota. The city also has 58602, which is used for P.O. Box addressing. This distinction is useful because a search for Dickinson ZIP codes can produce both numbers even though they do not serve exactly the same addressing purpose.
The United States Postal Service identifies Dickinson, North Dakota with the ZIP codes 58601 and 58602. Current USPS postal documentation continues to list the pair together for Dickinson.
For someone completing an address form, sending a parcel, registering a business location or checking a delivery address, the important point is that the correct code depends on the type of address being used.
| ZIP code | General use | Location |
| 58601 | Standard addressing | Dickinson, North Dakota |
| 58602 | P.O. Box addressing | Dickinson, North Dakota |
Understanding 58601 and 58602
ZIP codes are part of the United States Postal Service addressing system. They help organise mail into increasingly precise geographic and delivery areas.
In Dickinson, the two commonly associated codes have different practical roles.
58601 is the standard code most people are looking for when they ask for the Dickinson ZIP code. It is the code generally associated with physical street addresses in the city.
58602, meanwhile, is used for P.O. Box purposes. A P.O. Box is a numbered compartment at a postal facility rather than a physical delivery point such as a house, apartment or commercial building.
This means that simply knowing the city name is not always enough to select a ZIP code. The complete mailing address matters.
Dickinson ZIP Code at a Glance
| Address situation | ZIP code to check |
| Typical street address | 58601 |
| P.O. Box | 58602 |
| City | Dickinson |
| State | North Dakota |
| State abbreviation | ND |
USPS records have consistently associated both 58601 and 58602 with Dickinson. A recent USPS five-digit scheme document lists 58601–58602 for Dickinson, ND.
Why the Correct ZIP Code Matters
A ZIP code may appear to be a small detail, but it can affect several everyday processes.
For ordinary post, an accurate ZIP code supports automated sorting and routing. For online purchases, it can help determine delivery availability, shipping calculations and address validation. Businesses may also use ZIP codes when maintaining customer records or checking service areas.
There is another practical reason to distinguish 58601 from 58602: a form may ask specifically for a street address or a P.O. Box. In that situation, using the wrong code can create an address mismatch.
For example, someone entering a physical Dickinson residence would normally need the ZIP code associated with that street address rather than automatically selecting the P.O. Box code.
Dickinson, North Dakota in Context
Dickinson is a city in western North Dakota and serves as an important regional centre. The city is officially recognised in current U.S. Census geographic data as Dickinson city, North Dakota.
Its location is relevant when distinguishing the city from places with similar names elsewhere in the United States. Searching for “Dickinson zip code” without specifying the state can produce results for other communities named Dickinson.
Adding North Dakota or ND makes the intended location clear:
Dickinson, ND 58601
That is generally the format someone expects when entering a standard Dickinson street address, although the complete address should always determine the final ZIP code.
Common Mistakes When Searching for the Dickinson ZIP Code
One common mistake is treating 58601 and 58602 as interchangeable. They are both connected with Dickinson, but their postal applications differ.
Another is assuming that every address in a city must use one ZIP code. Postal boundaries do not necessarily follow simple municipal boundaries, and different delivery arrangements can result in different ZIP codes.
A third mistake occurs when an online form automatically suggests a ZIP code. Autocomplete can be useful, but it should not replace checking the complete address when accuracy matters.
Practical Checks
| Situation | What to verify |
| Sending a letter | Street or P.O. Box address |
| Ordering online | Complete delivery address |
| Completing a form | Whether it asks for street or P.O. Box |
| Business records | Official registered or physical address |
| Moving to Dickinson | ZIP code attached to the new address |
The Practical Difference Between a Street Address and a P.O. Box
The simplest way to understand the two codes is to focus on the destination.
A street address identifies a physical location where mail can be delivered. A P.O. Box identifies a postal box at a post office.
Therefore, someone asking for the standard Dickinson ZIP code will generally be looking for 58601. Someone specifically using a Dickinson P.O. Box may encounter 58602 instead.
The distinction is particularly useful for businesses, organisations and residents who maintain both a physical location and a postal box.
What the Postal Records Show
The association between Dickinson and these ZIP codes is not a recent internet convention. USPS documentation has listed 58601 and 58602 for Dickinson across multiple versions of its postal materials. Historical USPS records also show the same pairing.
This provides useful context when older addresses, directories or archived documents contain either number. However, when dealing with a current delivery, the complete address should take priority over an old database entry.
The Future of Dickinson Zip Code Information in 2027
ZIP codes are unlikely to become less relevant simply because more transactions are digital. Physical deliveries remain dependent on accurate addressing, while online businesses continue to use postal data for fulfilment and location validation.
The more important change is likely to be how people access address information. Digital checkout systems, mapping platforms and automated address verification increasingly present ZIP codes alongside complete addresses.
For Dickinson, the distinction between the standard 58601 code and the P.O. Box-associated 58602 code should remain useful for people trying to convert an informal location description into a correctly formatted postal address.

Conclusion
The answer to the question “What is the Dickinson zip code?” is usually 58601 when referring to a standard street address in Dickinson, North Dakota. The city also uses 58602 for P.O. Box addressing.
That two-code distinction explains why different directories or search results may show different numbers for the same city. It does not necessarily indicate conflicting information. Instead, the codes can serve different postal purposes.
