New Mexico Real Estate Email Signature Rules — the 33% Rule, and an Email Duty Nobody Else Has
New Mexico sets a precise numeric floor — the brokerage’s trade name and telephone number in type no smaller than 33% of your own name — and adds a duty no other state in this series has: identify yourself as a licensed New Mexico broker on real-estate phone calls, texts and emails.
Step by step
Include the brokerage's registered trade name
16.61.32.8(B) NMAC requires the “trade name… as registered with the commission”. Not the qualifying broker’s personal name — the registered trade name. A trade name must be registered with the Commission before it is used.
Include the brokerage's registered telephone number
The same subsection requires the “current brokerage office telephone number as registered with the commission”. New Mexico is the seventh state in this series to require a brokerage phone number. Additional numbers may be added.
Set both at least 33% of the size of your name
16.61.32.8(C), the provision that binds associate brokers: the trade name and telephone number “shall be prominently displayed in a type size not less than thirty-three percent of the type size of the associate broker’s name, or in the case of a team of associate brokers, the team name.” Note the comparator is your name, not the largest text in the message.

A separate duty, and unique in this series. 16.61.17.9(P) NMAC requires an associate broker to “identify oneself on real estate related phone calls, texts or emails as a licensed New Mexico real estate broker.” The parallel rule for qualifying brokers is 16.61.16.9(T). Effective since January 2021.
Skip the license number
Verified — and this one was decided rather than merely absent. The Commission voted against a licence-number-in-advertising rule in June 2016. Of thirty-four states checked, only California and Nevada require one.
Do not expect a size exemption for email
The rule exempts “electronic displays of limited information, such as thumbnails, text messages, links and tweets of 200 characters or less”, where linked to a compliant display. Email appears in neither list — neither the enumerated media nor the exemption — so it gets no character-based safe harbour.
Do not advertise under any other trade name
16.61.17.9(I): an associate broker shall not engage in real estate activity “under a trade name(s) other than the trade name(s) of the qualifying broker with whom the broker is affiliated.” And advertising you did not prepare must go to the qualifying broker for approval before release.
The email duty that is not an advertising rule
Most states in this series leave you to work out whether an email is advertising. New Mexico creates a separate obligation that applies to email regardless.
Read it carefully, because it is narrower than it looks. It requires disclosure of your licensee status. By its terms it does not require the brokerage name, the telephone number, or a licence number.
So a New Mexico signature has two tracks. Every real-estate email must say you are a licensed New Mexico real estate broker. And if the email also advertises property or real estate services, the advertising rule adds the registered trade name and phone at the 33% floor.
That second half is a reasonable application rather than a settled one — no Commission guidance construes email under the advertising rule, and “advertising” is not a defined term anywhere in the Commission’s rules or the statute.
New Mexico decided against the licence number
Across this series the licence-number myth has usually traced to a proposal that quietly died, or to a rule one board over. New Mexico is different: the Commission considered it and voted it down.
On 20 June 2016 the Commission rejected a rule that would have required licence numbers on all advertising, adopting instead a narrow duty tied to contract-track documents. That surviving rule — 16.61.16.9(S) — requires the qualifying broker’s name, contact information and licence number on “any written document… that has the potential to become an express written agreement”.
Listing agreements and purchase agreements are in scope. A marketing email is not, and neither is a signature block.
The state's own code is the stale one here
An inversion of the pattern this series has documented in nine states. New Mexico’s compiled administrative code serves an out-of-date version of this rule — carrying the pre-2021 text of subsection D and a history line ending in 2017, with the January 2021 amendment missing entirely. The Commission links to that stale copy from its own site.
Cornell, for once, is correct — it carries the amended subsection and cites the 2021 register entry properly. Do not “correct” it against the state publisher on this rule.
The amendment was validly adopted: it appears in the New Mexico Register, in the Commission’s adopted-rules posting, and in the Commission’s own rule book. The compilation simply missed it — the state’s update index for that year lists eleven sibling parts from the same package and omits this one.
There is a second defect in the official text. The history note printed at the foot of the advertising part says it was “replaced by 16.61.31 NMAC, Advertising/Disclosure”. 16.61.31 is Signage — the rule about the physical sign at your office entrance. The advertising part is 16.61.32. The error sits in the state’s compiled text and Cornell reproduces it.
New Mexico has no team rule
The word “team” does appear — but in exactly one substantive place, and only as a measuring stick. The 33% clause says the floor is measured against “the associate broker’s name, or in the case of a team of associate brokers, the team name”.
There is no team registration, no naming requirement, no banned words, and no team-formation filing. New Mexico is the fourteenth state in this series with no team rule, with that one caveat.
Everyone here is a broker
New Mexico abolished the salesperson licence — the rule creating it is marked repealed. Both licence classes are brokers: a qualifying broker qualifies and supervises the brokerage, an associate broker is affiliated with one qualifying broker.
Two consequences for a signature. An associate broker calling themselves a “broker” is accurate here, unlike in states where that would overstate a licence class. And the 33% floor by its terms binds associate brokers — a qualifying broker advertising under subsection (B) owes the trade name and phone but has no stated size floor.
How current is this?
The advertising rule was last amended effective 3 January 2021, and that amendment changed only subsection D — the owner-broker ownership disclosure — which has no bearing on a signature. The substantive requirements above date from 1 January 2017.
Checked against the state’s own annual update indexes: no changes to this chapter in 2024, 2025 or 2026. The only real-estate-adjacent activity in those years was in the appraiser, appraisal-management and home-inspection chapters.
State law vs. the NAR Code
No New Mexico rule restricts professional designations or job titles. The statute does supply the hook on association marks: it is a ground for discipline to use “any trade name or insignia of membership in any real estate organization of which the licensee is not a member”. Beyond that, NAR’s Code and your local association’s rules are contractual and are not enforced by the Commission.

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.
Trade name and phone, at the right proportion
New Mexico measures the brokerage name against yours at a fixed 33% floor, and wants the registered phone number too. Autograph builds the signature once at the right proportions, installs it into Apple Mail in one click, and sets up your iPhone by QR code so the ratio survives.

How small can the brokerage name be in my New Mexico signature?
No smaller than 33% of the type size of your own name — or of the team name, if you use one. Both the registered trade name and the registered brokerage telephone number are subject to that floor. Note the comparator is your name specifically, not the largest text in the message.
Do I have to say I'm a licensed broker in my emails?
Yes, and this is separate from the advertising rule. 16.61.17.9(P) NMAC requires you to “identify oneself on real estate related phone calls, texts or emails as a licensed New Mexico real estate broker”. It is a status disclosure — by its terms it does not itself require the brokerage name or phone number, though the advertising rule may add those.
Does New Mexico require my license number in advertising?
No — and it was decided, not merely omitted. The Commission voted against such a rule in June 2016, adopting instead a narrow duty covering documents that could become an express written agreement. Listing and purchase agreements are caught; a marketing email is not.
Is there an exemption for short posts?
Yes, but a narrow and precisely drawn one: “thumbnails, text messages, links and tweets of 200 characters or less”, and only where linked to a display carrying the full disclosures. Email is not on that list — nor on the list of enumerated media — so no character-based exemption is available to a signature block.
