Illinois Real Estate Email Signature Requirements (Including the City-and-State Rule, 2026)
Illinois wrote a rule for electronic communication rather than leaving email to inference, and it asks for something unusual: the city and state of your sponsoring broker’s office. It also flips its team-name rule between advertising and email, which is the trap most Illinois agents fall into.
Step by step
Use your own licensed name — a team name will not do
68 Ill. Adm. Code 1450.720(g)(1) requires your name “as licensed with the Division”, and says a team name “may be used in addition to the individual licensee’s name.” In an email signature the team name is an extra, never a replacement.
Add your sponsoring broker's name
225 ILCS 454/10-30(f): “The sponsoring broker’s business name and the name of the licensee must appear in all advertisements, including business cards.” And under 10-30(d) a sponsored licensee “may not advertise under the licensee’s own name” alone. For a franchise, the business name includes the franchise affiliation as well as the individual firm.
Add the city and state of your broker's office
The requirement almost nobody outside Illinois has: 1450.720(g)(3) asks for “the city and state where the sponsoring broker’s physical office registered with the Division is located” — or, for a virtual office, a direct link to the broker’s virtual office website.
Make the broker's name equal or larger
10-30(f): where an advertisement carries a team name or an individual’s name, “the sponsoring broker’s business name shall be at least equal in size or larger.” Note this is stricter than Texas, which only asks for half the size. The rule offers three ways to satisfy it — equal-or-larger font, equal-or-larger area, or a logo that incorporates the broker’s name at that size.
Or skip the manual setup
Autograph designs the signature on your Mac and installs it into Apple Mail in one click — images hosted at permanent URLs, assigned to the right account, and re-applied automatically when a macOS update or iCloud sync wipes it.

1450.715(b)(1): “a logo, emblem, label, trademarked image, or similar identification used by the sponsoring broker is not considered a part of the sponsoring broker’s name unless it contains the sponsoring broker’s name.” A bare brand mark does not discharge the requirement.
Skip the license number — Illinois does not require it in your ads
No advertising provision in the Act or in Part 1450 requires one. Illinois does require licence numbers in one place — a brokerage’s virtual office website must display a registry of sponsored licensees and their numbers — but that is the firm’s website, not your signature.
Designated managing broker? You must say so
10-30(g) requires those designated with the Department as a designated managing broker to identify themselves as such in advertising (signs excepted). Other managing brokers may call themselves a managing broker, but not a designated one.
Using a nickname? File it first
Your name must be the name as licensed or registered. Under 1450.150(b), a licensee who regularly practises under “an alias, diminutive, or nickname” must notify the Division — so “Mike” for “Michael” in your signature is a filing, not a style choice.
The rule that was written for email — without using the word
Illinois is one of the few states with a provision aimed squarely at electronic communication rather than at advertising in general. 68 Ill. Adm. Code 1450.720(g) requires a licensee using “any electronic or digital means of communication” to include, in the initial communication with a member of the public or another licensee: their name as licensed, the sponsoring broker’s name, and the city and state of the broker’s registered office.
Be precise about one thing: the word “email” does not actually appear in that rule, or anywhere in the advertising sections of the Act. “Any electronic or digital means of communication” plainly covers email in ordinary reading, and that is how it is universally applied — but it is an inference, not a named match, and we could find no IDFPR bulletin or FAQ that says “email signature” in terms.
The team-name trap
Illinois treats team names differently in advertising than in communication, and this catches people out.
In advertising and marketing (1450.720(d)(1) and (e)(1)), a team name may be substituted for the individual licensee’s name.
In electronic or digital communication (1450.720(g)(1)), the team name may be used “in addition to the individual licensee’s name.”
So a billboard can carry the team name alone. An email signature cannot. Your own licensed name has to be there.
Blind advertising, and why it is expensive
Illinois has a named offence for getting this wrong. A “blind advertisement” is defined in 225 ILCS 454/1-10 as one that does not include the sponsoring broker’s complete business name or, for electronic advertisements, does not provide a direct link to a display with all the required disclosures. Using one is a disciplinary violation under 20-20(a)(28), carrying a fine of up to $25,000 per violation. A signature missing the brokerage name is the textbook example.
Team names: the statute and the rule do not quite agree
Worth knowing before you name a team. The statute, 10-30(a), says team names “may not contain inherently misleading terms, such as ‘company’, ‘realty’, ‘real estate’, ‘agency’, ‘associates’, ‘brokers’, ‘properties’, or ‘property’” — flatly, with no qualifier.
The rule, 1450.715(a)(2), lists the same terms but adds a safe harbour: unless the term is followed by the word “team”. That is a genuine tension between the statute and the agency’s own regulation. The rule reflects IDFPR’s current position; the statute is unqualified. If you are choosing a name, this is a question for your managing broker rather than a settled point.
Currency — and a stale source to avoid
The advertising rule 1450.715 was amended effective 7 July 2025, and the statute’s advertising section was amended by P.A. 103-236 effective 1 January 2024. Two cautions: Cornell’s Legal Information Institute still shows the pre-2025 text of 1450.715, and the widely-circulated Illinois REALTORS® advertising checklist is a 2019 document that predates both the 2021 electronic-communication rule and the 2025 amendments — it contains nothing on digital disclosures at all.
One long-range note: every section of the Act carries a scheduled repeal date of 1 January 2030 under the State’s sunset provisions. That is routine reauthorisation, not an expiry, but it means the citations here have a horizon.
State law vs. the NAR Code
Everything above is Illinois law, enforced by IDFPR against your licence. The NAR Code of Ethics is a membership contract enforced by your association. Illinois law touches it at one point only: 20-20(a)(13) makes it a disciplinary matter to use “any trade name or insignia of membership in any real estate organization of which the licensee is not a member” — a prohibition on claiming what you do not hold, not a requirement to display anything.

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.
Four required elements, one signature
Your name, your broker’s name at equal-or-greater size, and the office city and state — on the first message to every new contact. Autograph builds it once, installs it into Apple Mail in one click, and sets up your iPhone by QR code so the mobile version carries the same disclosures.

Can I just use my team name in my Illinois email signature?
No. Illinois splits this: in advertising and marketing a team name may be substituted for your name, but in electronic or digital communication it may only be used “in addition to” your own licensed name. Your name has to be in the signature.
Does Illinois require my license number in my email signature?
No. No advertising provision in the Act or in Part 1450 requires it. The one place Illinois does require licence numbers is a brokerage’s virtual office website, which must display a registry of sponsored licensees and their numbers — that is the firm’s obligation, not yours.
Why do I have to include a city and state?
Because the electronic-communication rule asks for it. 1450.720(g)(3) requires “the city and state where the sponsoring broker’s physical office registered with the Division is located” — or, if the brokerage runs a virtual office, a direct link to its virtual office website instead. Illinois appears to be alone in requiring this in a signature.
How big does my sponsoring broker's name have to be?
At least equal in size or larger than the team name or your own name — stricter than Texas, which asks only for half the size. The rule accepts equal-or-larger font, equal-or-larger area, or a logo incorporating the broker’s name at that size. A logo without the name in it does not count at all.
