What is a Form 211?
Form 211 is the form which must be completed pursuant to FINRA Rule 6432 and submitted to the FINRA OTC Compliance Unit to initiate or resume quotations in the OTCBB, OTC Markets, or any other quotation medium pursuant to SEC Rule 15c2-11 . To view or print the Form 211, please visit our Forms Page . A 211 Addendum Form must be submitted in addition to the Form 211 for the OTCBB.

Do financials submitted with the Form 211 have to be audited?
The periodic reporting requirements relied upon by FINRA Rule 6530 require annual audits of an issuer's financial statements for quoting on OTCBB. However, current FINRA rules do not require audited financial statements for quoting on other quotation mediums , but they should be prepared in accordance with GAAP or, for foreign issuers, in accordance with their home country's accounting standards.
