CrowdStreet has two ways to verify your accredited status.
Use VerifyInvestor.com via your CrowdStreet investing account (instructions are outlined in this article: How do I access VerifyInvestor.com?)
Use a qualified, independent third party verifier, such as your CPA, attorney, or wealth advisor. You can use the verification letter template below.
Once you have your letter, you can upload it to your account through your Investing Account under Accreditation verification.
For more information on how to use a qualified, independent third party verifier, refer to this article: How do I use a qualified, independent third-party verifier to verify my accreditation status?
