“TTY” usually means teletypewriter, an old communication device used for typed messages. Today, it is most often used to refer to a phone service or feature that helps people who are deaf, hard of hearing, or have speech difficulties communicate by text.
In everyday life, you may see “TTY” on phone settings, customer service pages, or public service information. It often tells you that a number supports text-based communication through a TTY device or a similar relay service.
