Most "real estate email signature" templates online were written for no state in particular — a headshot, a title, a phone number, a logo. That's fine until your state's real estate commission opens a file, because in most states an email signature legally counts as advertising, and advertising has rules: what name you use, whether your brokerage has to appear, and sometimes whether your license number does too. This post covers exactly what five of the largest states require, with a picker to find yours, so you can fix a signature before it becomes a complaint instead of after.
Five states isn't all fifty, but the pattern across them is consistent enough to tell you what to check even if yours isn't listed.
Texas's TREC FAQ states directly that email is covered as an "advertisement" under its advertising rule. Florida's rule extends its "clear and conspicuous" brokerage-name standard to email and text, not just print. New York's Department of State guidance says its advertising rules apply "on social media," which its broader advertising checklist ties to the same disclosure list as any other ad. If your state hasn't published guidance this specific, assume email counts — it's the safer default, and it's what most state commissions that have addressed it directly have concluded.
New York's regulation requires brokers and salespersons to advertise under the name they're licensed with the Department of State — a nickname is allowed only alongside the full licensed name, not instead of it. California's disclosure statute similarly ties the required name to the licensee's actual identity, not a marketing name. If you go by a shortened or married name day-to-day, check whether your state requires the licensed version to appear too.
Florida requires the brokerage's licensed name in every advertisement, placed clearly and conspicuously, with the individual agent's name never larger than the brokerage's. Texas requires the broker's name at no smaller than half the size of the largest contact-info text in the ad. Illinois requires the sponsoring broker's name to be as large as, or larger than, the individual or team name. None of these are met by a signature that's all headshot, personal name, and team branding with the brokerage logo shrunk into a corner.
California is the outlier among the five: Business & Professions Code §10140.6 requires your name, your 8-digit DRE license identification number, and your responsible broker's identity on solicitation materials meant to be a consumer's first point of contact — and a companion regulation caps how small the license number's font can be relative to the rest of the ad. Texas, by contrast, does not require a license number in advertising at all under Rule 535.155. Don't copy a California-style license-number line onto a Texas signature assuming it's universally required — check your own state first.
A new brokerage, a title change (agent to associate broker, for instance), or a team rebrand all reset your compliance — New York explicitly bars using a license title like "broker" or "licensed sales agent" if that's not your actual, current designation. Put a signature review on the same checklist as updating your MLS profile when any of those change.
The statute targets "solicitation materials" for first point of contact with a consumer — DRE's own list of covered material types includes electronic and online advertising, so a cold-outreach signature is squarely inside it.
Read the source rule ↗General information, not legal advice — advertising rules change and your brokerage may layer stricter requirements on top of the state minimum. Confirm with your broker or state commission before you ship a new signature to your whole team.
A signature template designer optimizing for broad appeal has no incentive to bake in California's license-number-and-font-size rule or Illinois's broker-name-prominence rule — those requirements would look like clutter to someone in a state that doesn't require them. The result is templates tuned for visual appeal everywhere and legal compliance nowhere in particular.
It's natural for an agent building a personal brand to make their own name and headshot the visual anchor of the signature, with the brokerage logo added almost as an afterthought. Florida, Texas, and Illinois all have some version of a rule against exactly this pattern — the brokerage isn't allowed to be the smallest or least prominent element.
Because most of the states we checked don't require a license number in ordinary advertising, agents who move from a state that does (California) to one that doesn't (Texas) sometimes drop it entirely out of habit, or keep it purely as a trust signal without realizing that where it IS required, there's also a minimum font size tied to it.
"Broker" sounds more authoritative than "Associate Broker" or "Sales Associate," so it creeps into signatures as a shorthand — but New York's rule specifically prohibits using a title that doesn't match your actual license type, and vague titles like "licensed sales agent" are called out by name as non-compliant.
Real estate teams often want the team brand to dominate the signature — team logo, team tagline, team Instagram handle. Texas's rule specifically measures the sponsoring broker's name against "the largest contact information for any sales agent, associated broker, or team name" in the ad, which means an oversized team name raises the bar for how large the broker's name has to be, not lowers it.
DRE requires your name, license number, and responsible broker's identity on first-point-of-contact solicitation materials, with a font-size floor on the license number.
TREC requires the license holder's name and the broker's name at a defined minimum size relative to other contact info — no license number requirement in the advertising rule itself.
FREC requires the brokerage's licensed name, clearly and conspicuously placed, never smaller than the individual agent's name.
DOS requires your licensed name, an accurate license type, your brokerage name, and your office address or phone.
In the states we checked here, yes — Texas and Florida both explicitly extend their advertising rules to email, and New York's guidance covers "social media" under the same disclosure list, which its checklist treats consistently across channels. Treat email as advertising by default unless your state has said otherwise.
Only if your state requires it. California does, under Business & Professions Code §10140.6, with a font-size rule attached. Texas does not require a license number under its advertising rule. Don't copy a license-number line between states without checking — an unnecessary number isn't a violation, but it signals the signature wasn't built for the state you're actually licensed in.
Build (or configure) a version of your signature per state and make sure the version going out from any state-specific email address or campaign matches that state's rule — the safest approach is to satisfy the strictest applicable rule if you can't easily split signatures by state.
In states with a relative-prominence rule — Texas and Illinois among the ones covered here — no. The broker or sponsoring broker's name has to meet a minimum size relative to the largest name in the signature, and an oversized team name raises that bar rather than exempting it.
Generally yes. State advertising rules are written to reach the individual licensee, and a template your brokerage handed you isn't a legal shield if it turns out to be missing a required disclosure. It's worth flagging any gap to your broker, since a fix at the template level protects everyone using it, not just you.
Your state's real estate commission or licensing board publishes its advertising rule directly — search "[your state] real estate commission advertising rule" or check the Association of Real Estate License Law Officials (ARELLO) directory of regulatory bodies for a link to the right agency.
Your email signature is advertising in most states, and the specific requirements — license number, brokerage prominence, exact license title — vary enough that a generic template can't cover all of them. Confirm your own state's rule using the picker above, build the disclosure lines it names into your signature once, and re-check only when your brokerage, title, or team branding changes.

IDFPR requires the sponsoring broker's business name at least as large as your individual or team name, plus your registered name.
Don't assume any of the above transfers directly — confirm your own state's current advertising rule before finalizing a template.
