Radio Button

A radio button user interface element, used in form fields with two or more choices. Differs from a checkbox, in that only one response can be selected.

This emoji generally shows the on/enabled state for the radio button, with a smaller circle inside a larger outer circle.

Note: this emoji is not supported in Twitter / X names, to minimize confusion with a verified checkmark. Learn more here.

Radio Button was approved as part of Unicode 6.0 in 2010 and added to Emoji 1.0 in 2015.
