Post-nominal letters
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, an academic degree, accreditation, an office, a 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.
