Okla. Admin. Code § 605:10 § 605:10-9-4

(a) Requirements and prohibitions.(1) A broker, when advertising, must use their registered business trade name or the name under which the broker is licensed; however, yard signs must also include the broker's office telephone number. A firm shall not register or use a trade name of another licensed firm. In addition, the advertisement must 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", as the case may be. Legal abbreviations following the trade name or name under which the broker is licensed shall be acceptable as long as they are easily identifiable by the public as such.
(2) No real estate advertisement shall show only a post office box number, telephone number or street address.
(3) A broker, when operating under a franchise name, shall clearly reveal in all office identification and in all advertising other than institutional type advertising designed to promote a common name, the franchise name along with the name of the broker or business trade name as registered with the Commission. A franchise name shall not be the complete business trade name. All institutional type franchise advertising shall indicate that each office is independently owned and operated.
(4) A licensee shall not advertise, either personally or through any media, to sell, buy, exchange, rent, or lease property when such advertisement is directed at or referred to persons of a particular race, color, creed, religion, national origin, familial status or handicap. The contents of any advertisement must be confined to information relative to the property itself, and any advertisement which is directed at or referred to persons of any particular race, color, creed, religion, national origin, familial status, age or handicap is prohibited.
(5) Any advertising in any media which is misleading or inaccurate in any material fact or in any way misrepresents any property, terms, values, services, or policies is prohibited.
(6) A licensee shall not advertise any property for sale, rent, lease, or exchange in any media unless the broker has first secured the permission of the owner or the owner's authorized representative and said permission has a definite date of expiration.
(7) Social networking. A licensee who is engaged in licensed activities through social networking mediums must indicate their license status and include their broker's reference as required elsewhere in this rule.
(8) A licensee shall not use a yard sign at the licensee's personal residence as a marketing tool, to make it appear the real property is for sale, lease or rent when such is not the case.
(9) A broker may, or authorize an associate to, promote a seller incentive with the consent of the seller. The publicity must clearly indicate the incentive is being offered by the seller and not by the licensee and that the promotion only applies to a seller's particular property or properties.

(2) All advertising by an associate must be under the direct supervision of the associate's broker.

If approved by a broker, an associate may include in the advertisement:

For the purposes of this section, "prominent, conspicuous and easily identifiable" means that the broker's reference shall be at least fifty percent (50%) or larger than any team reference included in the advertisement.
