Fax Texas Department of Transportation — Cover Sheet and Documents
A fax for a transportation permit request in Texas only helps if Texas Department of Transportation can match it to your case — which comes down to what you put on the cover sheet. For Texas residents in Texas and the Southwest, Texas Department of Transportation is the office behind the state's transportation permitting program. This page covers what to label, what to fax, and how to find the office's current fax number.
Does Texas Department of Transportation accept a fax?
You often apply for a DOT permit online, but fax still handles supporting documents: contractor prequalification paperwork, encroachment and access permits, and forms a district or maintenance office asked for. Either way, do not assume fax works everywhere — check the agency's rules for your document first.
Finding the official fax number
Because Texas Department of Transportation handles a transportation permit request through different offices, the right fax depends on your document. Check the form's instructions or the notice, verify the line on the official site, and keep it with your file.

Cover-sheet basics for faxing Texas Department of Transportation
The cover sheet does the routing work once your fax arrives. Include a callback number so the district office can reach you about the permit. A delivery confirmation then tells you the pages reached the agency.
When fax works for a transportation permit
An oversize/overweight supplement or a right-of-way permit is where fax fits a transportation matter. Include the route or highway number and the county so the district office can locate the work. The clearer the route and project identifiers, the faster the office can process the permit.

Federal agencies still write fax into new rules and notices
The Federal Register — the daily journal of U.S. federal rulemaking — regularly publishes rules and notices that reference fax as an accepted or required submission channel for filings with agencies like the IRS, SSA, and CMS. That is why fax remains a live requirement for many official forms even as electronic portals expand.
