"SEC Form 211" refers to FINRA's Form 211, an application required under SEC Rule 15c2-11 for broker-dealers to initiate or resume quotations for a security on the Over-the-Counter (OTC) market. The form serves to ensure that sufficient, accurate information about the issuer and its securities is publicly available to protect investors. It was previously submitted by a market maker to FINRA's OTC Compliance Unit for review, but now a Qualified IDQS (Independent Qualified Data Provider) or the OTC Markets Group can review it
