Post-nominal letters, also called post-nominal initials, post-nominal titles, designatory letters or simply post-nominals, are letters placed after a person's name to indicate that the individual holds a position, academic degree, accreditation, office, military decoration, or honour, or is a member of a religious institute or fraternity. An individual may use several different sets of post-nominal letters, but in some contexts it may be customary to limit the number of sets to one or just a few. The order in which post-nominals are listed after a name is based on rules of precedence and what is appropriate for a given situation. Post-nominal letters are one of the main types of name suffix. In contrast, pre-nominal letters precede the name rather than following it.
