This question has come up quite a bit this wedding season so I decided to share this post again.
These two cards are most often mistaken for the same purpose. But I am here to clear that up!! There is a different purpose for each card.
The Escort card (as shown) is the card that you traditionally find on a large table at the cocktail hour or entrance to the reception. This card is used to "escort" guests to their table. So traditionally the Escort card will list the name of the guest and their table assignment.
The Place card is the card that you will find at your "place" setting at the table. This card identifies which seat is yours to sit in at the table.
