The escort card is used to direct guests to their predetermined table seating arrangement for the wedding reception. It corresponds with a master seating chart, which may or may not designate guests to specific seats.
Generally, guests will find the escort card on a separate table as they enter the reception. The card will be marked with the guest's name and table assignment. The guest tables are either numbered or named, and the escort card is the guests' way of finding the table card they are looking for.
Further, if each table has preassigned seats, then a seating chart or escort card will direct guests to a specific table (labeled by number or name), where guests will find their name printed on separate place cards already on the table at each place setting.
Escort cards direct; place cards seat each individual. One or the other, or both may be used, depending on the formality and preferences of the couple.
Escort cards can be creative. They are not limited to "cards," but may be items. These items may be tied into the favors.
