Shaping An Accessible World

Telecommunications For the Deaf and Hard of Hearing Inc.

Washington DC—Site of 2009 TDI Conference—Where Access Begins!


TDI (formally known as Telecommunications for the Deaf and Hard of Hearing, Inc.) was established in 1968 originally to promote further distribution of TTYs in the deaf community and to publish an annual national directory of TTY numbers. 


Today, it is an active national advocacy organization focusing its energies and resources to address equal access issues in telecommunications, media, and information technologies for four constituencies in deafness and hearing loss, specifically people who are deaf, hard-of-hearing, late-deafened, or deaf-blind.

TDI is also the parent organization for the Community Emergency Preparedness Information Network (CEPIN) project.  The project intended  to promote awareness in emergency management and preparedness activities for special needs populations. You can visit CEPIN’s website at


TDI’s website is currently under renovation. Check back for a new and improved website shortly.
