South Dakota Real Estate Advertising Rules — the Guidance Isn't South Dakota's
South Dakota’s advertising law is four lines long and asks for one thing in a signature: the name of your firm. The document its own Commission links under “Guidance from SDREC” asks for your office city, every state you are licensed in, and a brokerage phone number — none of which is South Dakota law.
Two neighbouring states publish the same document and each took a position on it. Nebraska prints an explicit note that it is not mandated. Montana enacted it as a binding rule — then repealed it in 2025. South Dakota alone presents it bare, as its own guidance.
Step by step
Name the firm you are associated with
SDCL 36-21A-72(1): “Each advertisement shall clearly state the name of the firm with which an individual licensee is associated.” That is the whole of the identification requirement. No size rule, no placement rule, no proportion.
If you are soliciting, say you are a licensee
§ 72(3), added in 2019: any advertisement in which a licensee tries to secure listings, offers to buy, sell or lease, or performs any other licensed act “shall clearly disclose that the advertised acts or services are being offered by a licensee”. The same duty appears twice more in the unprofessional conduct statute.
If you advertise as a team, identify anyone unlicensed
§ 72(2) is South Dakota’s genuinely distinctive provision. Team advertising must state the brokerage name, must not suggest the team operates independently of the broker, and must “clearly identify the nonlicensed individuals included in the advertisement”. If your signature or team block lists a transaction coordinator or marketing assistant who holds no licence, that person has to be identified as unlicensed. No neighbouring state imposes this.

None is required. We searched the governing statute chapter and the live administrative article: there is no licence-number display duty, no telephone requirement, and nothing about your office location. The nearest genuine number duty concerns a time-share registration number placed on filed documents — a filing, not a display.
Do not follow the Commission’s linked guidelines as if they were rules
That document asks for the brokerage name on every email message, plus “the city where the licensee’s office is located”, plus “the other jurisdictions in which the licensee holds a licence”, plus a telephone number. None of those four elements exists anywhere in South Dakota law. Its own title says “Recommended”, and its operative verbs are “should”.
If you are selling your own property, say so
The proviso at the end of § 72 lets a licensee advertise their own property in their individual name, provided the advertisement discloses that the owner is a licensee. Unlike North Dakota next door, South Dakota compels no particular wording — there is no required “Owner/Licensed Broker” string.
All of it is in the statute; the rules are silent
South Dakota has no advertising regulation for licensees. We pulled the entire live administrative article: nineteen chapters, and the only advertising rule in any of them binds auctioneers. The team chapter contains a single rule, and it is a broker recordkeeping duty.
So the whole regime is four subdivisions of one statute. That is not unique — Minnesota is in the same position — but it does mean that anything presented as a South Dakota advertising rule is either the auction rule or not South Dakota at all.
The definition is narrower than any neighbour’s
SDCL 36-21A-2 defines advertising as any attempt, “by publication or broadcast, whether oral, written or otherwise, to induce a person to use the services of” a licensee.
That is limited twice over — by channel and by purpose. Every comparator that defines the term uses a medium-neutral formula instead: Iowa’s reaches “all forms of identification… disseminated in any manner and by any means of communication” and names email outright; North Dakota’s says “in any manner and by any means of communication”; Montana’s says “in whatever form”.
Two rules that cite an authority for continuing education
South Dakota’s two advertising-adjacent rules both cite rulemaking authority that no longer says what they think it says.
The team rule cites subdivision (11) of the Commission’s authority statute. The live statute has only nine subdivisions. When teams were added in 2019 they genuinely were (11) — but a 2021 act deleted two subdivisions and renumbered, moving teams to (9) and auctions from (7) to (5). Neither rule was conformed.
So today the auction advertising rule cites subdivision (7), which is now continuing education.
The guidance was never adopted, and never disclaimed
We searched 52 sets of Commission minutes covering 2019 to 2026. The word “advertising” does not appear once. The only mentions of the association that wrote the guidelines are conference travel motions.
So the document was never rescinded — but it was also never adopted, never discussed and never reviewed in any published minute. Minutes go back only to 2014 and the document dates from 2009, so its arrival is untraceable.
One more wrinkle: the Commission’s own published law book misprints the team subsection, rendering “advertisement” as “advertisements” against both the enrolled bill and the codified text. Minor — but it means the regulator’s own publication is not textually authoritative either.
What the internet gets wrong about South Dakota
- “South Dakota requires your licence number.” False. Nothing in the statute chapter or the live rules requires it.
- “South Dakota requires the brokerage phone number, your city, and the states you are licensed in.” False as law — and this one comes from the Commission’s own linked guidance, which is why it is so persistent.
- “South Dakota has an internet advertising rule.” It never has. Montana did, and repealed it in 2025; the two get conflated.
- “South Dakota’s team rule governs team names.” It does not. It governs disclosure, and the implication of independence — there is nothing about what a team may call itself.
An honest note on this page
South Dakota’s substantive requirements are thin, and a page built as a formatting checklist would not be worth writing. What makes it worth writing is the gap: a South Dakota licensee who follows the Commission’s own linked guidance will put four things into their signature believing the state requires them, when the state requires none of them — and the two neighbouring states using the identical source document each took an explicit position on it, while South Dakota did not.
What does your state actually require?
Pick a state. Every answer is taken from the current rule text and checked against that state’s own statute and regulations — not from a template, and not from the regulator’s summary of its own rules, which is wrong in twenty-six jurisdictions.
Name the firm, and make it render
South Dakota asks for your firm’s name and little else — the harder part is a signature that survives Gmail, Outlook and the next macOS update. Autograph builds it once, installs it into Apple Mail in one click, and re-applies it when an update wipes it.

What does South Dakota actually require in an agent’s email signature?
The name of the firm you are associated with. If the message is soliciting business — trying to secure a listing, or offering to buy, sell or lease — it must also disclose that the services are being offered by a licensee. That is the whole of it. No licence number, no phone number, no office city, no size or placement rule.
The Commission links Internet Advertising Guidelines. Do I have to follow them?
They are not South Dakota law. That document is an industry association’s 2009 model text, published with no adoption statement and no disclaimer; its own title says “Recommended” and its requirements are phrased as “should”. It asks for your office city, every jurisdiction you are licensed in, and a brokerage telephone number — none of which appears anywhere in South Dakota’s statute or rules. Following it does no harm; believing it is compulsory is simply wrong.
Does South Dakota require a licence number in advertising?
No. We searched the governing statute chapter and the entire live administrative article. The only number duty in the vicinity is a time-share registration number that goes on documents filed with the Commission — a filing obligation, not something you display.
My team includes an unlicensed assistant. Does that change my signature?
It can, and this is South Dakota’s most distinctive rule. Team advertising must “clearly identify the nonlicensed individuals included in the advertisement”. If a team block names someone who holds no licence, they have to be identified as unlicensed. None of South Dakota’s neighbours imposes an equivalent duty.
Is a normal client email even “advertising” in South Dakota?
Arguably not, though we would not build a signature on that argument. South Dakota’s definition is unusually narrow: an attempt “by publication or broadcast… to induce a person to use the services of” a licensee. A one-to-one email to an existing client is neither publication nor broadcast, and is not trying to induce anyone to retain you. No South Dakota authority resolves the point, and naming your firm costs nothing — so name it.
