Locate and Provide Your Texas Webfile Number

Your Webfile number is your "access code" to Webfile issued by the Comptroller's office. It is printed in the upper left corner of the tax report we mail to each taxpayer and on most notices. It is two letters followed by six numbers (Example: RT666666).

If you do not have your Webfile number, you can contact Texas DOR at (800) 442-3453 24 hours a day, 7 days a week. This automated system can provide a Webfile number if you can provide confidential information from a previously filed report. You can request a duplicate report via this automated system if you cannot provide the confidential information.
