The At-home card tradition began in Victorian times as a way to officially announce a newlyweds’ joint home together and the date at which they would begin living there. At-home cards were originally sent along with the Wedding Announcement or Wedding Invitation.
Today, at-home cards are still useful as a way to alert people of an address change after marriage. Many people also use these cards to announce a name change. Often, couples will send their cards out after the wedding and will include more information than just their home address. It may be useful to include second homes, as well as cell phone numbers and email addresses, along with any other means of contact for you and your new spouse.
