SEC Paper Form 144 Filings—Update and FAQs

Since the start of the pandemic, Form 144s have been filed both electronically and on paper mailed in to the SEC Public Reference Room. While The Washington Service has captured electronic filings in our database, the Reference Room was closed to the public between April 2020 and June 2022. Consequently, no mailed-in filings were disseminated by the SEC during that period. After the Reference Room’s limited opening in early June 2022, paper filings gradually became available. We make recent filings available the same day as they are released, and we have now integrated the older paper filings.

In this post we provide answers to your questions concerning the integration of mail-in 144 filings into the EZ-Insider website. As of mid-November 2022, we have processed all disseminated pandemic-delayed paper filings.


Q. What is a Form 144?

A. In a nutshell, the Form 144 is a required filing resulting from the SEC’s Rule 144, which requires disclosure and regulation when trading restricted and control securities. As a statement of intent to sell, their value (even retrospectively) is partially derived from their disclosure of broker information, derivative security types, and foreign filers’ recent activity. Prior to the pandemic, these forms were filed exclusively on paper, by mail. At the Reference Room's closure in April 2020, electronic filing via email became prevalent, although not adopted by all brokers. Paper Form 144s that have continued to be mailed in are currently being disseminated once a week by the SEC. [Click here for more info about Form 144s]

Q. What percentage of the filings were missing?

A. We estimate that electronic filings made up about 70% of all filings for the last two years, based on previous years' totals. The integration of mail-in 144 filings included an increase of about 30% to round out the total filings.

Q. Will the filings eventually be integrated into the website?

A. Absolutely. We strive to provide a comprehensive representation of the data; this now includes the older filings that were inaccessible prior to the Reference Room’s re-opening. The Form 144 data has been meticulously integrated into the database using our previously established and rigorous process, providing EZ-Insider users an accurate and full picture of the last two years. 

Q. Will the filings be released as headlines on partnered news wires?

A. As they are integrated into the system, the older filings will not be published as new headline articles on our partner news services (i.e., Bloomberg, Dow Jones, etc.). However, the filings and their data may be seen in the historical-style articles, retrospectively.

Q. Will this impact my data feed?

A. Data feeds will be assessed and augmented on a case-by-case basis. If you are a data client with questions or concerns, feel free to reach out to us at or call 301-913-5100.
