The wedding invitation tells guests where and when the wedding ceremony is taking place but reception cards tell guests where and when the reception is taking place. Reception cards are often needed if the ceremony and reception are happening at two different locations.
The reception card is usually purchased in addition to wedding invitations but there are alternatives to purchasing reception cards. Many wedding invitations have enough room for couples to put the reception wording below the wedding invitation wording. Seal and send wedding invitations from Ann’s Bridal Bargains are great examples of this. You can also find wedding invitations with reception cards included in the price like Sep and send wedding invitations from Ann’s.
