Once your filing has been received at GAO, you will receive an automated reply advising that a
file number and attorney will be assigned to the filing. The reply also will advise that the
filing information and status of the filing are available on our online Bid Protest Docket,
accessible via the Legal Products link on GAO's home page or by calling our protest status line
at 202-512-5436. If you do not receive an automated reply, GAO did not receive your e-mail filing.
To ensure your filing is received in a time manner, send your filing by another method or call
the bid protest status line for assistance.

New Process Coming:
This summer, GAO will establish a secure and easy-to-use web-based electronic bid protest filing and dissemination system (EPDS). EPDS will also provide automatic notice of a protest to the agency. Once it is live, all protesters will be required to use the system to file new protests, and there will be a $350.00 filing fee. Funds from the filing fee will be used to pay for the operation and maintenance of the system. This new process necessitates changes in GAO’s Bid Protest Regulations found at 4 C.F.R. part 21. You can view and comment on our Notice of Proposed Rulemaking, including the proposed filing fee, which is published in the Federal Register, by May 16, 2016. Additional materials regarding e-filing will be added to our website, so please check back for updates.
