What is the order for designatory letters after a person's name?

Answer 1

The use of letters after an individual's name (postnominal letters) follows a prescribed order and may vary according to the nature of the address:

Note: The abbreviation 'Bt' (for a baronet), and 'Esq', if applicable, precede all other letters.

Order of Letters after the NameThe series of other letters are grouped, and ordered, either by regulations or by custom as follows:

1. Orders and Decorations conferred by the Crown (Crown Honours).

2. Appointments in the following order, Privy Counsellor, Aide de Camp to HM, Honorary Physician to HM, Honorary Surgeon to HM, Honorary Dental Surgeon to HM, Honorary Nursing Sister to HM, and Honorary Chaplain to HM. Thus PC, ADC, QHP, QHS, QHDS, QHNS and QHC.

3. Queen's Counsel, Justice of the Peace and Deputy Lieutenant. Thus QC, JP and DL.

4. University Degrees [in date order, list the higher of any qualifications in the same subject].

5. (a) Religious Orders (b) Medical Qualifications.

6. (a) Fellowships of Learned Societies, (b) Royal Academicians and Associates, (c) Fellowships, Memberships, etc, of Professional Institutions, Associations, etc, and (d) Writers to the Signet.

7. Member of Parliament.

8. Membership of one of the Armed Forces, such as RN or RAF.

It is important to keep the group order, even if the individual letters in groups 4, 5 and 6 present difficulties.

The nature of the correspondence determines which series of letters should normally be included under groups 4, 5 and 6. For instance, when writing a professional letter to a doctor of medicine, one would normally add more medical qualifications than in a social letter.

On a formal list, those who have letters signifying Crown Honors and Awards are usually given only the principal letters in groups 4, 5 and 6 (for example MD, FRCS, FRS).
