What Is a Letter of Invitation?

A letter of invitation serves as a formal request for an individual’s presence or attendance to an event, dinner, celebration or formal occasion. Letters of invitation are often distributed for weddings, retirement ceremonies, graduation celebrations, birthdays, anniversary parties and formal galas in the community.

A letter of invitation includes information about the host, the location of the event, time and date of the celebration and attire desired at the party. The letter should also include details about the occasion, such as a person’s age for a birthday celebration or the number of years worked when a person is retiring and hosting a retirement party.
