NLRB Fax Number — File Unfair Labor Practice Charges
The National Labor Relations Board takes unfair labor practice charges, representation petitions, and related filings by fax, but through its regional offices rather than a single national line. Each NLRB region covers a defined geographic area, and you file where the alleged violation took place. People commonly fax completed charge forms, election petitions, objections to elections, and supporting evidence to the region handling their dispute.

Tip: File with the NLRB regional office that covers the location of the alleged violation, since that's where jurisdiction sits. Name the employer, the union if one is involved, and the specific conduct you're alleging so the regional staff can open or attach the matter correctly. Keep a delivery confirmation, because charge-filing deadlines under the Act are strict and proof of timely submission matters.
