Oklahoma Real Estate Advertising Rules — the 50% Rule, and What It Actually Says
Oklahoma is the only state in this series whose size rule is ambiguous in its own text. It requires the broker’s reference at “at least fifty percent (50%) or larger than” yours — wording that can be read two very different ways, and which is almost always quoted in the stricter form the rule does not use.
Step by step
Use the broker's registered trade name or licensed name
OAC 605:10-9-4(a)(1): a broker advertising “must use their registered business trade name or the name under which the broker is licensed”. Yard signs must additionally carry the broker’s office telephone number.
Make clear you are a broker, not a private party
The same paragraph requires the advertisement to “indicate that the party is a real estate broker and not a private party, to include, but not limited to, ‘agency’, ‘company’, ‘realty’, or ‘real estate’”. Oklahoma is unusual in naming the acceptable words.
Never let contact details be the whole advertisement
(a)(2): “No real estate advertisement shall show only a post office box number, telephone number or street address.”
Include your broker's reference at the required size
(b)(3): an associate must include the broker’s name “in such a way that the broker’s reference is prominent, conspicuous and easily identifiable” — which the rule then defines as “at least fifty percent (50%) or larger than any associate reference included in the advertisement.” See below on what that actually means.
Or skip the manual setup

(b)(1) and (c)(1): neither an associate nor a team may advertise under their own name alone, and all advertising must be “under the direct supervision of” the broker.
Skip the license number in advertising
Oklahoma requires your licence number on contracts — and only where you are personally the owner or purchaser. Nothing requires it in an advertisement. Of twenty-nine states checked, only California and Nevada do.
Selling your own property? Disclose in writing that you are licensed
(d)(1) requires a licensee who owns or is buying the property to disclose in writing in all advertisements that they are licensed. The statute backs this up, making it a disciplinary cause to advertise “without disclosing in writing that the licensee is a real estate licensee”.
Team? Register it, pay $100, and put “team” or “group” in the name
605:10-9-3.2 requires the broker to register each team at $100 per team name, before any licensable activity. The name must be unique statewide, and “all registered team names shall contain the word ‘team’ or ‘group’”.
The 50% rule says two different things
The rule defines “prominent, conspicuous and easily identifiable” as the broker’s reference being:
“at least fifty percent (50%) or larger than any associate reference included in the advertisement.”
Read one way, the broker’s name must be at least half the size of yours. Read the other, it must be at least half again as large as yours. Those are opposite ends of a wide range, and the difference decides whether a signature complies.
We could find no Commission interpretation resolving it. What we can say is that the widely-circulated paraphrase — “the broker’s name must be 50% larger than yours” — is not what the rule says. It picks the stricter reading and drops the “at least fifty percent” half of the phrase.
Practical answer: set the broker’s name at least as large as your own. That satisfies either reading, and it is what the neighbouring states require anyway.
Renumbering on 1 November 2026
An amendment published in the Oklahoma Register as adopted — heard in December 2025 and approved by joint resolution in May 2026 — is due to take effect on 1 November 2026. Two things matter:
- A new provision: “Team members are prohibited from holding themselves out as owner of a firm that provides brokerage services.”
- A renumbering: the team version of the broker-name and 50% rule moves from (c)(3) to (c)(4). Any guide citing 605:10-9-4(c)(3) for that rule is correct today and wrong from 1 November 2026.
This page cites (b)(3) for the size test throughout, because that subsection number is stable across the amendment. The substance of subsections (a) and (b) is unchanged.
Arriving the same day, and worth knowing if you automate anything: 605:10-9-1(g) extends the broker’s responsibility to “virtual or remote assistants, and any software-based tools (including chatbots, Artificial Intelligence Models, or Generative AI)”. Oklahoma is the second state in this series to legislate about AI in this area, after Wisconsin’s advertising-disclosure rule.
Where email fits
Oklahoma never names email. It reaches it through a broad definition instead — 605:10-1-2 defines advertising as “all forms of representation, promotion and solicitation disseminated in any manner and by any means of communication, to include social networking”.
Two electronic channels are named specifically, and both are stricter than the general rule:
- Social networking — (a)(7): a licensee engaged in licensed activities through social networking “must indicate their license status and include their broker’s reference”. Note the licence-status element, which the general advertising rule does not require.
- Websites — the broker’s reference “shall appear on every individual page and/or frame”.
The Commission's checklist will not keep you compliant
Oklahoma is the fourteenth state in this series where the regulator’s published material falls short of its own rules — though here the problem is omission rather than error.
The Commission’s Advertising Checklist asks whether the broker’s name is “prominent, conspicuous and easily identifiable” — but omits the 50% definition entirely. It also omits the prohibition on advertisements showing only a box number, phone or address; omits the franchise disclosure requirements; and never mentions websites or email.
Nothing in it is wrong. But a licensee who passes the checklist can still be in breach of the rule, which is a poor property for a compliance checklist to have.
Cornell serves two different versions of this rule
A trap specific to Oklahoma, and a new one in this series. Cornell hosts the advertising rule at two separate URLs — one current, correctly showing the November 2024 amendment, and one stale, showing 2019 as the latest version. Both are live, and nothing on either warns you the other exists. Elsewhere in this series Cornell has simply been out of date; here it is out of date and current at the same time, depending which link you land on.
Oklahoma’s own rules portal is the authority — note that the Secretary of State paths some sources still cite are dead, returning an authentication error rather than a redirect.
Three citation corrections
- There is no “associate broker” in Oklahoma. The licence classes are broker, broker associate, sales associate and provisional sales associate — plus branch broker. “Broker associate” and “associate broker” are not interchangeable, and only one of them exists here.
- The team rule is 605:10-9-3.2, not 3.1. There is no section 605:10-9-3.1 — the numbering jumps.
- “Last amended November 2013” is stale by a decade. The advertising rule was amended in 2018, 2019 and 2024, and changes again on 1 November 2026.
One further caution: a cease-and-desist rule, 605:10-17-3.1, appeared in the 2026 notice of rulemaking intent but does not appear in the final adoption. It is not law.
State law vs. the NAR Code
No Oklahoma rule restricts which titles or designations may appear in an advertisement, and none requires you to state your licence class in ordinary advertising — the only status-disclosure duties attach to social networking and to advertising your own property. REALTOR®, GRI and the rest are NAR membership matters. And as noted above, NAR’s limited-display exemption has no Oklahoma counterpart.

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.
Broker's name, sized to satisfy either reading
Oklahoma’s size rule can be read two ways, and a signature retyped on a phone satisfies neither. Autograph builds it once with the broker’s name set correctly, installs it into Apple Mail in one click, and sets up your iPhone by QR code so the proportions hold.

Does the broker's name have to be 50% larger than mine in Oklahoma?
That is the usual paraphrase, and it is a misquote. The rule says the broker’s reference must be “at least fifty percent (50%) or larger than” the associate reference — wording that can mean half the size, or half again as large. No Commission interpretation resolves it. Setting the broker’s name at least as large as your own satisfies either reading.
Does Oklahoma require my license number in advertising?
No. Oklahoma requires your licence number on contracts, and only where you are personally the owner or purchaser of the property. There is no licence-number requirement in the advertising rule.
What are the rules for an Oklahoma team name?
Teams must be registered by the broker at $100 per team name, before any licensable activity, and the name must be unique across the state. Every registered team name “shall contain the word ‘team’ or ‘group’”. From 1 November 2026, team members are also barred from holding themselves out as the owner of a brokerage firm.
Is there an exemption for short-format posts or thumbnails?
Not in Oklahoma. NAR’s Code has an exemption for “electronic displays of limited information”, but that is a membership standard. Oklahoma’s rule contains no limited-display exemption, and its social-networking provision is stricter than the general rule — requiring you to indicate your licence status as well as the broker’s reference.
