Geographic familiarity makes people more likely to pick up the phone, and it builds the kind of trust that out-of-state lines rarely earn. Sign up with Omnivoice and start connecting with customers across the state today.
Where is the 605 Area Code Located?
Many phone area codes are tied to specific geographic regions and help identify where a phone number is based. They are commonly used across the United States to organize telecommunications and assign numbers to different locations.
Areas Served
The 605 area code covers South Dakota, which is home to just under 900,000 people. Sioux Falls, the largest city, is a growing business hub with thriving sectors in banking, healthcare, and retail. Rapid City anchors the western part of the state near the Black Hills and supports significant tourism-related commerce. Both cities, along with Aberdeen, Brookings, Watertown, and Mitchell, fall under this regional code.
Residents tend to value straightforward, community-oriented service. Local consumers are more likely to call back a local number they recognize. Omnivoice makes it easy for any small business to get a phone number that reflects the region where their customers live and work.
Time Zone
South Dakota spans two time zones — Central Time Zone (CT) in the east and Mountain Time Zone (MT) in the west. Omnivoice lets you configure after-hours routing so that any call to your phone number outside business hours goes directly to voicemail or a backup line, regardless of the caller’s time zone.
Is It Toll-free?
The 605 area code is not toll-free. It is a standard geographic code tied to a specific region within the country code +1. Toll-free numbers use codes like 800, 888, or 877 and are billed to the receiving party. For most small businesses, a local geographic code carries more credibility with customers than a toll-free alternative.
Why Does Local Area Code Matter?
A local phone number with a 605 area code does more than just route calls. It shapes how customers perceive your business from the very first ring. When combined with a virtual phone system, it also gives businesses flexibility in how they handle communication. Here is why having a geographic code works in your favor:
- Higher answer rates: Studies consistently show that people are more likely to answer a call from a phone number they recognize as regional. When your code matches the caller’s area, they feel less guarded.
- Stronger trust signal: It signals to customers that you are invested in their community. It is the digital equivalent of having a local address on your storefront.
- Consumer values in the region: Residents of South Dakota place a premium on personal relationships and community ties. A regional code reinforces that your business is not just a faceless national chain.
- Alignment with local search and directories: Matching your number to your service area strengthens consistency across local search listings, Google Business Profile, and directory citations, which matters for local SEO.
- Regional business reputation: The entire state of South Dakota has a tight-knit business community, particularly in sectors like agriculture, healthcare, and financial services. Having a local presence signals that your company is a recognized regional player.

Top Features You Will Get With Your 605 Number
Every 605 number comes with a full suite of tools built for business calls. Here is what you get from day one:
- Multi-Level IVR: Set up a professional menu that greets every caller with a custom message and automatically routes them to the right person or department. You can configure multiple menu options, set different greetings for business and after-hours calls, and update everything without technical help. It keeps your phone number organized and accessible at every level of your operation, giving even a small team the appearance of a well-run, full-scale business.
- Webphone: Use your business phone number to make and receive calls directly from your browser — no downloads or plug-ins required. The Omnivoice webphone uses WebRTC technology to deliver clear audio and works in any modern browser. It is ideal for remote teams or anyone who prefers a desktop-based experience without a dedicated desk phone.
- Voicemail with Transcription: Every voicemail left on your local phone number is automatically transcribed to text so your team can scan messages at a glance without listening to each recording. Transcripts are delivered as notifications and stored in your account for easy reference. Your team never misses an important message, even during busy periods or after hours.
- MMS Messaging: Send and receive multimedia messages — photos, documents, and more — from the same phone number you use for voice calls. No separate messaging account or app is needed. MMS works alongside standard SMS, so your customers can reach you any way they prefer.
- Call Recording: Automatically record incoming and outgoing phone calls, or record on demand. Useful for training, quality assurance, dispute resolution, and reviewing customer conversations to improve service. Recordings associated with your business number are stored in your account. They can be played back or downloaded at any time, providing your team with a reliable reference for every customer interaction.
- User Extensions: Assign a dedicated extension to each team member so callers can reach the right person directly — no need to go through the main menu every time. Extensions are linked to your phone area code and ring across all connected devices without requiring a fixed desk setup.

605 Area Code History and Overlays
The 605 area code was created in 1947 as part of the original North American Numbering Plan established by AT&T and the Federal Communications Commission. It has served the entire state since then — one of the few codes in the country to cover a whole state without a split or partial reassignment. Related area codes in the region:
- 701 — covers all of North Dakota
- 406 — covers all of Montana
- 307 — covers all of Wyoming
- 612 — Minneapolis, Minnesota
- 303 — Denver, Colorado
Because South Dakota has a relatively low population density and volume has remained manageable, no new code shares the same geographic territory, and existing customers never face a forced change in number. Your business line stays uniquely tied to the region without the confusion that overlays can create in more densely populated areas.
Connect with More South Dakota Customers
A familiar area code is one of the simplest ways to show customers across the state that your business is part of their community. A local phone number builds the kind of first-impression credibility that toll-free lines rarely achieve. People are more likely to trust a number they recognize as regional. That trust translates directly into more conversations and more conversions.

FAQ
The 605 area code is not exclusively assigned to either cell phones or landlines — it is a geographic code assigned to both mobile and landline numbers. Under the North American Numbering Plan, codes are assigned by location, not by device type. When you set up a line through Omnivoice, it functions as a virtual VoIP number that works on mobile devices, desktop browsers, and deskphones — so you are not locked into any single device.
If you miss a call on your 605 number, Omnivoice handles it according to the routing rules you have configured. They can be forwarded to another team member, placed in a queue, or sent to voicemail with automatic transcription. You receive the transcript via text notification so you can review it at a glance. You can also set up IVR menus to offer callers a self-service option while you are unavailable.
