Rule 506(b) vs 506(c): What's the Difference and Why It Matters to Investors

The difference between 506b vs 506c boils down to two things: who can invest and how the deal gets marketed. Rule 506(b) lets issuers raise unlimited capital from accredited investors (plus up to 35 non-accredited investors) but bans general advertising. Rule 506(c) allows public advertising but restricts participation to verified accredited investors only. Which structure a platform uses directly affects your experience as an investor.

What Is Regulation D?

Both 506(b) and 506(c) fall under Regulation D of the Securities Act of 1933. Reg D provides exemptions that let companies raise money without the full SEC registration process — which can cost $1 million or more and take months. Instead, issuers file a simple Form D with the SEC after the sale begins.

Regulation D is the backbone of private capital markets. In 2024, Reg D offerings raised over $2 trillion — dwarfing the roughly $200 billion raised through traditional IPOs. Most private real estate deals, venture capital funds, and private equity offerings use one of these two rules.

How Rule 506(b) Works

Rule 506(b) is the older, more established exemption. It has three defining characteristics:

No general solicitation. The issuer cannot publicly advertise the offering. No Facebook ads, no Google campaigns, no billboards. The deal can only be shared through pre-existing relationships. In practice, this means you need to already be on a platform's radar or connected to the sponsor before you hear about the deal.

Up to 35 non-accredited investors. While most 506(b) deals target accredited investors, the rule allows up to 35 "sophisticated" non-accredited investors. These investors must receive extensive disclosure documents similar to what a registered offering would provide. Most issuers skip this option because the extra disclosure requirements are expensive.

Self-certification of accredited status. This is the big one for investors. Under 506(b), platforms can accept your word that you meet accredited investor requirements. You check a box, maybe answer a questionnaire, and you're in. No tax returns, no bank statements, no CPA letters.

How Rule 506(c) Works

Rule 506(c) arrived in 2013 as part of the JOBS Act. Congress wanted to modernize capital raising, and the centerpiece was lifting the ban on advertising for certain private offerings.

General solicitation allowed. Issuers can advertise anywhere — social media, podcasts, email blasts, webinars. This is why you see platforms like CrowdStreet and EquityMultiple running Google ads for specific deals. Before 506(c), that would have been illegal.

Accredited investors only. No non-accredited investors, period. The trade-off for advertising freedom is a stricter investor pool.

Mandatory third-party verification. Here's where 506b vs 506c creates the biggest friction for investors. Under 506(c), the issuer must take "reasonable steps" to verify that every investor is actually accredited. Self-certification doesn't cut it. You'll need to provide one of the following:

• Tax returns or W-2s from the past two years showing $200,000+ income ($300,000+ joint)
• Bank, brokerage, or other account statements showing $1 million+ net worth (excluding primary residence)
• A written confirmation letter from a CPA, attorney, or registered investment advisor
• A verification letter from an SEC-recognized third-party service

The verification process typically takes 2-5 business days. Services like Verify Investor and Parallel Markets handle this for many platforms, usually at the issuer's expense.

506(b) vs 506(c): Side-by-Side Comparison

Advertising: 506(b) prohibits it; 506(c) allows it.

Investor types: 506(b) allows accredited plus up to 35 non-accredited; 506(c) requires all investors to be accredited.

Verification: 506(b) accepts self-certification; 506(c) requires documented proof.

Disclosure requirements: 506(b) must provide extensive disclosures to non-accredited investors; 506(c) has no special disclosure rules beyond the standard PPM.

Fundraising limit: Neither has a cap — both allow unlimited raises.

SEC filing: Both require Form D within 15 days of the first sale.

Which Platforms Use Which Rule?

Most online investment platforms have gravitated toward 506(c) because their business model depends on marketing to attract investors. You can't build a web platform and then tell people they need a "pre-existing relationship" with you.

CrowdStreet primarily uses 506(c) for its marketplace offerings, which is why you'll go through a verification process before investing. EquityMultiple similarly operates under 506(c) for most deals. AcreTrader uses 506(c) for its farmland offerings, requiring verification through a third-party service.

Some platforms use a hybrid approach. They might operate a 506(b) offering for their main fund (where investors come through referrals) and 506(c) for deals they want to advertise broadly.

Platforms operating under different exemptions — like Regulation A+ or Reg CF — don't face these restrictions at all, which is one reason platforms like Fundrise can accept non-accredited investors.

Why the Distinction Matters to You

If you value privacy, 506(b) is more convenient. Self-certification means you don't have to hand over tax returns or financial statements to a platform or third-party verifier.

If you want deal flow, 506(c) offerings are easier to find. Because issuers can advertise, you'll discover more opportunities through normal channels — search engines, social media, investment newsletters.

If you're not accredited, 506(b) is technically your only path into Reg D offerings, but very few issuers use the non-accredited investor allowance. Your better options are Regulation A+ or Regulation Crowdfunding deals.

If you're evaluating a deal's legitimacy, the 506b vs 506c distinction tells you something about the sponsor's approach. A 506(c) offering has gone through extra compliance steps. The verification requirement adds a layer of friction that some argue filters out less serious investors.

The Verification Process Step by Step

For 506(c) offerings, verifying your accredited status follows a standard process:

1. Create an account on the platform and indicate your interest in a deal.
2. Select your qualification method — income, net worth, or professional credentials.
3. Upload documentation or authorize a third-party verifier to check your records.
4. Receive your verification letter, typically valid for 90 days.
5. Invest once the platform confirms your status.

Some platforms cover the verification cost. Others pass it to the investor — expect $50-$150 per verification if you're paying out of pocket.

Common Misconceptions About 506(b) vs 506(c)

"506(c) offerings are safer." Not necessarily. The verification requirement protects the issuer's compliance, not your investment returns. A verified accredited investor can still lose money on a bad deal.

"506(b) means the deal is exclusive." The no-advertising rule creates that impression, but plenty of mediocre deals use 506(b). The exemption structure says nothing about investment quality.

"You can't switch between the two." Issuers generally choose one structure and stick with it for a given offering, but they can use different rules for different offerings. A sponsor might run one fund under 506(b) and another under 506(c).

Frequently Asked Questions

What is the main difference between 506(b) and 506(c)?

The core difference is advertising. Rule 506(b) prohibits general solicitation but allows self-certification and up to 35 non-accredited investors. Rule 506(c) permits public advertising but requires all investors to be accredited and verified through documentation or third-party services.

Do I need to be accredited for both 506(b) and 506(c)?

Rule 506(c) requires all investors to be accredited. Rule 506(b) allows up to 35 non-accredited investors who qualify as "sophisticated," though most issuers choose not to include them due to extra disclosure costs. Practically speaking, most deals under either rule target accredited investors.

How long does 506(c) verification take?

Most third-party verification services complete the process within 2-5 business days. You'll need to upload tax returns, financial statements, or obtain a letter from a CPA or attorney. Once issued, verification letters typically remain valid for 90 days before you need to re-verify.

Can a company switch from 506(b) to 506(c)?

Not easily for the same offering. Once an issuer has begun raising under 506(b), switching to 506(c) creates legal complications — especially if they've already accepted self-certified investors. Most issuers choose one structure before launching and run separate offerings under different rules if needed.

Why do most online platforms use 506(c)?

Online platforms depend on digital marketing to attract investors, and 506(b) prohibits general solicitation. A platform running Google ads or social media campaigns would violate 506(b) rules. Rule 506(c) was essentially created for this business model — advertising is allowed as long as investor verification is rigorous.

Does 506(b) or 506(c) affect my returns?

The exemption structure doesn't directly affect returns. However, 506(c) offerings may have slightly higher compliance costs that sponsors pass through as fees. The real impact is on deal access and the friction of getting verified, not the underlying investment performance.
