Which three-digit number is designated for use in the United States as a telecommunications relay number for assisted calls to deaf and hard-of-hearing people?
1) 211
2) 511
3) 711
4) 811
I caught a whiff of a commercial today for this service and realized I hadn't remembered the number. We all know 411 and 911, but there's a set of government-designated rapid-dialing numbers, known as the N11's. Here's what I got from the FCC's Web site information sheet on N11's:
211: Assigned for community information & referral services
311: Assigned nationwide for non-emergency police and other government services
411: Unassigned, but used virtually nationwide by carriers for directory assistance
511: Assigned for traffic and transportation information
611: Unassigned, but used broadly by carriers for repair service
711: Assigned nationwide for access to Telecom Relay Services
811: Unassigned, but used by local exchange carriers for business office use
911: Unassigned, but used nationwide for emergency services
011 and 111 are unavailable because "0" and "1" are used for switching and routing purposes.
