US Supreme Court Fax Number — Fax Court Filings and Documents

The Supreme Court of the United States lists a Clerk's Office fax line at 202-479-3011 in Washington, DC. The Court's procedures are formal and specific, and fax is not a substitute for the official filing methods set out in the Supreme Court Rules, which govern paper submissions and the Court's electronic filing system. Use the fax number for correspondence with the Clerk's Office rather than as a way to lodge a petition or brief, and confirm any requirement with the Clerk before sending.

What You Can Fax to US Supreme Court

  • Motions and briefs
  • Case correspondence
  • Emergency filings
  • Attorney appearance forms
  • Settlement documents
Tip: Always include the docket number on every page so the Clerk's Office can match your fax to the right case. The Supreme Court Rules dictate paper format, color of brief covers, and the number of copies required, none of which a fax can satisfy, so treat fax as a channel for letters and routine correspondence rather than formal filing. If you are responding to a deadline, send early in the day and keep the Send FAX Mail confirmation as a record of when the Clerk's machine received your pages.

The published fax number for the Clerk's Office at the Supreme Court of the United States is 202-479-3011. Call the Clerk's Office to confirm what they will accept by fax before you rely on it.

No. The Supreme Court Rules require petitions and briefs to be filed as paper documents in a specific format, along with electronic filing through the Court's system for represented parties. Fax does not meet those requirements and should be used only for correspondence.

Routine correspondence with the Clerk's Office, such as letters about a pending matter, is the practical use for the fax line. Anything that counts as a formal filing must follow Rule requirements for paper and electronic submission instead.
