What Are the Advertising Limits of Reg D 506(b), 506(c), and Reg A+?

Rule 506(b) bans public advertising of your offering entirely, Rule 506(c) permits it but requires you to verify that every investor is accredited, and Regulation A+ permits it to the general public but requires SEC qualification before you can accept a single dollar. That one distinction decides whether your fund can run paid ads, publish a live deal page, or post about an open raise on LinkedIn. Pick the wrong exemption and you are not just limiting your marketing reach; you risk breaking the exemption your entire raise depends on. Here is what each one actually allows.

Key Takeaways

• Rule 506(b) prohibits general solicitation and general advertising, which means no paid ads, no public deal pages, and no open webinars about a live offering. You can only approach investors you already have a pre-existing, substantive relationship with.
• Rule 506(c) allows fund managers to advertise publicly to accredited investors, but every purchaser must be verified as accredited. Self-certification is not enough under 506(c).
• The March 2025 SEC no-action letter simplified 506(c) investor verification, making general solicitation practical at scale for the first time since the rule took effect in 2013.
• Regulation A+ lets you market a real estate offering to non-accredited investors, but the SEC must qualify your Form 1-A offering statement before you can close any sale.
• Antifraud rules and platform ad policies apply to all three exemptions, so compliant advertising is about how you say it as much as whether you are allowed to say it.

What Counts as General Solicitation?

General solicitation is any offer of securities made to the public rather than to people you already know. The term matters because it is the dividing line between the three exemptions.

The SEC treats the following as general solicitation: publicly accessible websites describing your offering, social media posts about a live deal, paid advertising on Meta, Google, or LinkedIn, mass emails to purchased or rented lists, press releases about the raise, and seminars or webinars whose attendees were recruited through advertising.

Critically, it is the offer that triggers the rule, not the sale. A single LinkedIn post about an open deal counts even if nobody invests. There is no cure for it after the fact.

Why Can't You Advertise a 506(b) Offering?

Rule 506(b) is the traditional private placement, and it comes with an explicit prohibition on general solicitation and general advertising under Rule 502(c). In exchange for that silence, you get real flexibility on who can invest: unlimited accredited investors, plus up to 35 non-accredited but sophisticated investors in any rolling 90-day period.

You also get a lighter verification standard. Under 506(b), accredited investors can self-certify their status through a subscription questionnaire. You need a reasonable belief, not documentary proof.

The pre-existing, substantive relationship

Because you cannot solicit publicly, 506(b) fundraising runs entirely through relationships. The SEC requires that a relationship be both pre-existing, meaning it was formed before this offering began, and substantive, meaning you know enough about the person's financial circumstances and sophistication to evaluate whether the investment suits them.

That standard is why most 506(b) sponsors build an investor list months before a deal goes live. An intake questionnaire, a real conversation, and a documented timeline of the relationship are what separate a compliant offer from a prohibited one.

SEC staff guidance has confirmed that a password-protected investor portal works for 506(b) as long as prospects are screened and qualified before they ever see a specific deal. The public side of your site builds the list. The gated side shows the offering.

What you can still publish under 506(b)

The prohibition is on advertising the offering, not on marketing your firm. Under 506(b) you can still publish educational content about your asset class, share market commentary, run a podcast, build an email list, and describe your track record and team, as long as none of it references a live securities offering or invites investment in one.

In practice this is why content compounding works so well for 506(b) sponsors. Brand-level content builds the relationship pipeline that the rule requires, and it keeps working long after it is created.

What Can You Advertise Under Rule 506(c)?

Rule 506(c) is the exemption built for advertising. Adopted under the JOBS Act and effective September 23, 2013, it permits issuers to broadly solicit and generally advertise an offering. Paid ads, public deal pages, webinars, podcasts, press coverage, and cold outreach are all on the table.

The trade-off is strict: every single purchaser must be an accredited investor, and you must take reasonable steps to verify it. Non-accredited investors are prohibited under 506(c), with no exceptions.

The verification trade-off

Verification is a separate legal obligation from whether the investor is actually accredited. A signed questionnaire alone does not satisfy it. The rule provides safe harbor methods: reviewing two years of tax returns, reviewing bank or brokerage statements dated within the prior three months, or obtaining a written confirmation from a registered broker-dealer, SEC-registered investment adviser, licensed attorney, or CPA.

This friction is the reason 506(c) was underused for over a decade. Asking a prospective LP to hand over tax returns kills conversion at exactly the wrong moment in the funnel.

What changed in March 2025

On March 12, 2025, the SEC's Division of Corporation Finance issued a no-action letter confirming that a high minimum investment amount can satisfy the reasonable-steps verification standard. If an issuer requires a minimum investment of at least $200,000 from a natural person or $1,000,000 from an entity, obtains written representations that the investor is accredited and that the investment is not financed by a third party for the purpose of making it, and has no knowledge contradicting those representations, the staff agreed that verification is satisfied.

That guidance is what finally made advertised 506(c) raises practical at scale. The right framing for fund managers: 506(c) has been legally available since 2013, but only became operationally viable after the 2025 verification simplification.

One useful detail: the SEC has confirmed that an issuer running a 506(b) offering can switch to 506(c) mid-raise. Offers made before general solicitation begins are not integrated with what follows, so long as every purchaser after the switch is verified. You cannot switch back.

How Does Regulation A+ Compare?

Regulation A+ is often described as a mini-IPO. It permits full public advertising to anyone, including non-accredited investors, which makes it the only one of the three that opens a real estate offering to a retail audience.

The cost is process. You must file a Form 1-A offering statement and have it qualified by the SEC before any sale closes. That review takes months and real legal spend.

Tier 1 versus Tier 2

Tier 1 permits raises up to $20 million in a 12-month period but requires state-by-state registration and review, which makes national advertising campaigns expensive to clear.

Tier 2 permits raises up to $75 million and preempts state registration, so a single national campaign works. In exchange, Tier 2 requires audited financials and ongoing SEC reporting: an annual Form 1-K, semiannual Form 1-SA, and current reports on Form 1-U. Tier 2 also caps non-accredited individual investors at 10% of the greater of their annual income or net worth, though they may self-certify that figure.

Most real estate sponsors using Reg A+ structure as a REIT, because entities that would be classified as investment companies are ineligible for the exemption.

Testing the waters

Reg A+ offers one marketing advantage neither Reg D exemption matches: testing the waters. You can publicly solicit non-binding indications of interest both before and after filing your Form 1-A, which lets you build a waitlist while the SEC review runs.

Those materials must state that no money is being solicited or accepted and that no commitment can be accepted until qualification. After qualification, offers must be accompanied by or preceded by the offering circular, which is why Reg A+ deals cannot advertise on television or radio but can advertise anywhere a link to the circular fits.

506(b) vs 506(c) vs Reg A+: What's Allowed?

Use this as a channel-planning reference before any campaign goes live. A check means permitted, an X means prohibited, and a conditional entry means permitted only on the stated terms.

What Limits Apply No Matter Which Exemption You Choose?

Choosing 506(c) or Reg A+ unlocks advertising, but it does not remove every constraint. Four rules apply across all three.

Antifraud provisions. Section 17(a) of the Securities Act and Rule 10b-5 apply to every communication regardless of exemption. Misleading performance claims, cherry-picked track records, and projections presented without risk disclosure create liability even in an offering you are fully entitled to advertise.

The Investment Adviser Marketing Rule. If your firm is an SEC-registered investment adviser, Rule 206(4)-1 governs your fundraising communications. Testimonials and endorsements require specific disclosures and written agreements, gross performance cannot be shown without net performance given equal prominence, and hypothetical or targeted returns carry additional conditions.

Broker-dealer compensation. Paying a marketing agency, finder, or lead vendor a percentage of capital raised is the classic trigger for broker-dealer registration analysis. The SEC has long treated transaction-based compensation as a hallmark of acting as a broker. Flat-fee and retainer arrangements avoid that exposure.

Platform advertising policies. Meta now requires financial-services advertisers to use a Special Ad Category that removes age and gender targeting, restricts geographic radius, and disables lookalike audiences. Google's consumer-finance policy similarly bars targeting by age, gender, marital status, or ZIP code in the US. These policies bind 506(c) and Reg A+ campaigns even though securities law permits the ads, which is why Predictive Investor Targeting now depends far more on first-party data, intent signals, and landing-page qualification than on demographic filters.

Which Exemption Fits Your Raise?

For most growth-stage real estate fund managers, the decision comes down to three questions.

• Do you need non-accredited capital? If yes, Reg A+ is your only option among these three. If no, stay in Reg D and avoid the qualification timeline and reporting burden.
• Do you need to advertise? If your existing investor list cannot fill the raise, 506(c) is the practical choice. If your list can cover it, 506(b) keeps the process simpler and lets you accept a limited number of sophisticated non-accredited investors.
• Can your minimum investment support simplified verification? If a $200,000 individual minimum fits your deal structure, the 2025 guidance makes 506(c) meaningfully easier to run than it was before.

At FundFunnels, the 4 Quadrants Model maps directly onto this decision, because the exemption you choose determines which stages of the cold-to-committed funnel you are legally allowed to operate. A 506(b) sponsor builds relationships at the top and gates everything below. A 506(c) sponsor can run paid acquisition straight into a qualified investor journey.

Frequently Asked Questions

Can I switch from 506(b) to 506(c) in the middle of a raise?

Yes. SEC guidance confirms that offers and sales made under 506(b) before general solicitation begins will not be integrated with subsequent 506(c) activity. Every purchaser after the switch must be verified as accredited, and you should amend your Form D. You cannot switch back to 506(b) once you have advertised publicly.

Does posting about my fund on LinkedIn break 506(b)?

It depends on what you post. Content about your firm, your market, or your asset class is fine. A post about a live offering, or one inviting people to invest in a current deal, is general solicitation and can cost you the exemption even if nobody invests.

Is a webinar general solicitation?

It depends entirely on how attendees were recruited. A webinar promoted through paid ads or an open public link is general solicitation. A webinar invited only to investors with whom you already have a pre-existing, substantive relationship is not.

What happens if I accidentally generally solicit during a 506(b) raise?

You lose the 506(b) safe harbor for that offering, and because general solicitation is incompatible with the underlying private placement exemption, you usually cannot fall back on it. That exposes you to investor rescission rights and regulatory risk. In some cases you can pivot the remainder of the raise to 506(c), but only if you verify every purchaser from that point forward. This is a conversation to have with securities counsel immediately, not after closing.

The Bottom Line

The advertising rules are not an obstacle to work around; they are the constraint that shapes your entire investor acquisition strategy. Decide the exemption first, then build the funnel that exemption permits. Sponsors who reverse that order end up with campaigns they cannot legally run, or worse, a raise they cannot legally close.
