A name suffix in the Western English-language naming tradition, follows a person's full name and provides additional information about the person.

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.
