How to File Communications with Advertising Regulation

Firms can file communications for review via Advertising Regulation Electronic Files (AREF), an online application. In addition, firms can use AREF to view, print and save the department’s review letters.

The vast majority of communications are filed electronically through AREF. However, firms still wishing to submit hard copies must use the Advertising Regulation Filing Cover Sheet. Effective September 28, 2015, FINRA migrated the AREF system to a new platform that allows firms to submit advertising-related files through a wide variety of formats and to submit larger files.

About Advertising Regulation Electronic Files (AREF)

Advertising Regulation Electronic Files (AREF) is a Web-based application that enables FINRA member firms to file communications with the public for review by FINRA's Advertising Regulation Department. In addition, firms may use AREF to view, print, and save letters about communications filed for review. Firms may also access real time filing fee information via AREF.

Effective October 16, 2017, FINRA enhanced AREF to allow firms the option to submit websites and web pages in their native format (e.g., .html). Firms that choose to use the new capability will package websites or web pages in a compressed file format and submit them through the AREF System for review by FINRA. Firms will include in their submissions a manifest that lists each unique web page address (Uniform Resource Locator or URL) submitted for review. FINRA also enhanced AREF to allow firms the option to submit the Android version of their mobile application file (e.g., .apk) as supporting documentation when filing the point-in-time capture of the application.

The enhanced AREF system provides firms with the ability to:

  • submit audio and video files in formats such as mp4, wmv and wav, as well as files in MS Office formats such as Excel and PowerPoint and, not be limited only to PDF files;
  • submit file sizes up to 500MB;
  • save filings in draft status prior to submission to FINRA;
  • upload more than two supporting documents on an initial filing; and
  • perform improved searches and filtering functions on filings submitted.

Use of the systems is voluntary. FINRA will continue to send comment letters by mail (and, for expedited filings, by facsimile) unless you choose to receive electronic copies only.

  • You may go directly to FINRA Gateway via the following URL:
  • Questions regarding obtaining access to the system can be directed by phone to (800) 321-6273 or by email.
  • Questions regarding the comment letters that appear on AREF or about the advertising rules may be directed to the Advertising Regulation Department staff at (240) 386-4500.
