How To Use The Federal Information Relay Service (FIRS)

To place a call to a TTY user through FIRS, the caller should dial 1-800-877- 8339 (voice or TTY). The FIRS line will emit TTY tones, then fax tones, then a voice operator will come on the line to assist nondisabled callers. FIRS is available from 8 a.m. to 8 p.m., Monday through Friday (except holidays), and may be used for any official government business.
