To vote for Dancing with the Stars, you text the specific keyword for your favorite couple to the number 21523. After each couple performs, their unique keyword will appear on the screen, and you just need to send that keyword via text to 21523 to cast your vote. There is no account needed for text voting, and you can send up to 10 votes per couple per episode by text. This number and process are currently used in Season 34 of the show.
