When listing the honours and awards enjoyed by any person it is not customary to include the Order of St John, as this is a Royal Order of Chivalry and not a State Order, and so confers no precedence.^[6] The statutes of the order state (statute 32(2)) The letters specified ... may be used ... but admission or promotion to any Grade of the Order ... shall not confer any rank, style, title, dignity, appellation or social precedence whatsoever.

The Grades of the Order of St John are:

Grade I	Bailiff or Dame Grand Cross	GCStJ
Grade II	Knight or Dame of Justice or Grace	KStJ or DStJ
Grade III (a)	Chaplain	ChStJ
Grade III (b)	Commander (Brother or Sister)	CStJ
Grade IV	Officer (Brother or Sister)	OStJ
Grade V	Member (since 2008) Serving Brother or Serving Sister (before 2008)	MStJ SBStJ or SSStJ
Grade VI	Esquire (no longer in use as of 2018)	EsqStJ

Fellowship or membership of learned societies, academies or professional institutions

These are generally placed in the order learned societies first, then Royal academicians, then professional institutions. There are two schools of thought as to how these should be ordered within each category: A & C Black's Titles and Forms of Address states that "As a general rule, letters should be shown in the order of the foundation of the societies, etc."^[3] Contrary to this, Debrett's consider that within learned societies: "There is no recognised order for placing these letters. In practice, where one society is indisputably of greater importance than another the letters are usually placed in that order."^[43]^{[N 20]} Similarly, for professional institutions: "[T]here is no recognised order for placing qualifications awarded by different bodies, a recipient usually places these letters on headed paper, business cards, etc, in order of importance to his particular profession."^[45] There is no clear distinction between a learned society and a professional institute. With regard to Royal Academicians, Debrett's says: "Although Royal Academicians come second in this list, it is not suggested that they yield in precedence to fellows of learned societies. In practice, the two lists do not coincide."^[46]

Black's notes that where a professional body or society has multiple grades of membership, only the highest is used except in professional correspondence, and that fellowships "election to which is a distinction" (e.g. FRS, RSA, RA, FBA) should be used on all correspondence, whereas initials only indicating support for a society are limited to correspondence on matters of interest to that society. Initials can also be used in professional contexts to indicate expertise.^[3] Debrett's also distinguishes between initials issued as an honour, and those available as a subscription, with only the former normally being used in social correspondence. The former include fellowships of "principal learned societies", including, in order of foundation, FRS, FSA, FRSE, FRSL and FBA.^[47]

In this table, all societies, institutions, etc. are listed alphabetically by substantive name,^{[N 21]} rather than attempting to establish an order of precedence.

Some post-nominals (and associated professional titles) are protected as "Professions Regulated by Professional Bodies Incorporated by Royal Charter" under the European professional qualification directives.^[48] These are indicated with an asterisk (e.g. CEng*).

Memberships and fellowships of the various medical Royal Colleges are listed post-nominally as medical qualifications (see the previous section) rather than with professional bodies and learned societies.

Chartered and other professional statuses

Some bodies award Chartered and other professional statuses with separate designatory letters from those indicating membership. These letters are placed before the designatory letters for fellowship or membership of the awarding body, e.g. CPhys MInstP. Where chartered status is a membership level within an institute, this is shown under that institute's entry above, e.g. Chartered Architectural Technologists, MCIAT, or Chartered Tax Advisor, CTA.

Membership of the armed forces and civilian services

In the armed forces, two or more branches may have officers with the same or similar titles, such as "Captain", which is a rank in the Royal Navy, Army and Royal Marines. To differentiate between the branches, post-nominals such as "RN" are used. However, such post-nominals are not used for the higher positions, since the higher officers are differently-titled in each branch.

This is the last set of post-nominals given by the Ministry of Justice and Debrett's; it is not included by Black's.

Notes

^ Esquire (or Esq as a suffix) is now commonly used in the UK in place of the prefix Mr in formal address;^{[citation needed]} according to the Dictionary of Genealogy it has no real meaning, while according to Buckingham Palace it is an entitlement of all British-born men.^{[citation needed]}
^ The Order of Saint Patrick is now dormant.
^ ^a ^b ^c The Order of the Star of India is now dormant.
^ ^a ^b ^c The Order of the Indian Empire is now dormant.
^ The Order of Victoria and Albert is now defunct; no appointments have been made since the death of Queen Victoria.
^ The Order of the Crown of India is now dormant.
^ ^a ^b The Indian Order of Merit is now dormant.
^ The Order of British India is now dormant.
^ The Indian Distinguished Service Medal is no longer awarded.
^ Previously known as the Colonial Police Medal (CPM).
^ Postnominals date from Sep 16 onwards, when it became a state award. Previous awards of the Merchant Navy Medal, awarded from 2005 to 2015, did not attract post-nominal letters. See http://www.merchantnavymedal.org/
^ The letters "PC" are normally only used to identify members of the Privy Council of the United Kingdom who are peers. The distinction is needed because peers already hold a prefix ("Rt Hon" or higher) even when they are not Privy Counsellors, while the same cannot be said of non-peers.^[7] However if the prefix "The Right Honourable" is omitted before a non-peer's name then the post-nominal letters "PC" may be used to identify a person's membership of the Privy Council.^[8]
^ Identified by post-nominal abbreviation only when citing legal reports, in every other circumstance identified by pre-nominal title^[9]
^ Placed here on the Ministry of Justice list but after memberships of learned societies, royal academies and professional bodies by both Debrett's and Black's
^ "Member of Parliament" is used in the UK and other Commonwealth countries to describe members of the lower house of Parliament only. In the UK, members of the House of Commons are described as Members of Parliament, like in Canada, but members of the House of Lords are not.
^ When the London Assembly was first established in 2000 there was some debate over its members' post-nominal letters. The most commonly used were "AM", "GLA", "MLA" and "GLAM". GLA is a short form of Greater London Authority, of which the London Assembly is part. A consensus eventually grew around the use of AM.
^ The exact post-nominals for degrees vary between courses and between universities, common ones are shown here, ordered according to the Framework for Higher Education Qualifications.^[12]
^ Use of Cantuar for Kent is rare and risks confusion with both Lambeth degrees and the University of Canterbury, NZ. The Latin name for Kent is Cantium (hence Cantiensis) which would give Cant (also used by the University of Canterbury, NZ); the University of Kent was originally the University of Kent at Canterbury.
^ Awarded to undergraduates who receive a BEng or MEng degree from a programme within the City and Guilds College-Imperial College London.
^ Debrett's previously added that: "Strictly speaking, [Learned Societies] should be arranged according to date of foundation or incorporation of the societies concerned, but some hold that those with a Royal Charter should take precedence."^[44] This has been deleted from the current advice.
^ I.e. by what they are a society or institute of or for, e.g. Aeronautical for the Royal Aeronautical Society. Bodies without a substantive name, such as the Royal Society, are listed at the top, ordered by their full names.
^ While based outside the UK, the RIA is an all-Ireland learned body covering Northern Ireland
^ Used only within the society

[5] Esquire (or Esq as a suffix) is now commonly used in the UK in place of the prefix Mr in formal address;^{[citation needed]} according to the Dictionary of Genealogy it has no real meaning, while according to Buckingham Palace it is an entitlement of all British-born men.^{[citation needed]}

[6] The Order of Saint Patrick is now dormant.

[India1-7] The Order of the Star of India is now dormant.

[India2-8] The Order of the Indian Empire is now dormant.

[9] The Order of Victoria and Albert is now defunct; no appointments have been made since the death of Queen Victoria.

[10] The Order of the Crown of India is now dormant.

[India3-11] The Indian Order of Merit is now dormant.

[12] The Order of British India is now dormant.

[13] The Indian Distinguished Service Medal is no longer awarded.

[15] Previously known as the Colonial Police Medal (CPM).

[16] Postnominals date from Sep 16 onwards, when it became a state award. Previous awards of the Merchant Navy Medal, awarded from 2005 to 2015, did not attract post-nominal letters. See http://www.merchantnavymedal.org/

[pc-20] The letters "PC" are normally only used to identify members of the Privy Council of the United Kingdom who are peers. The distinction is needed because peers already hold a prefix ("Rt Hon" or higher) even when they are not Privy Counsellors, while the same cannot be said of non-peers.^[7] However if the prefix "The Right Honourable" is omitted before a non-peer's name then the post-nominal letters "PC" may be used to identify a person's membership of the Privy Council.^[8]

[Legal-22] Identified by post-nominal abbreviation only when citing legal reports, in every other circumstance identified by pre-nominal title^[9]

[25] Placed here on the Ministry of Justice list but after memberships of learned societies, royal academies and professional bodies by both Debrett's and Black's

[mp-26] "Member of Parliament" is used in the UK and other Commonwealth countries to describe members of the lower house of Parliament only. In the UK, members of the House of Commons are described as Members of Parliament, like in Canada, but members of the House of Lords are not.

[mla-27] When the London Assembly was first established in 2000 there was some debate over its members' post-nominal letters. The most commonly used were "AM", "GLA", "MLA" and "GLAM". GLA is a short form of Greater London Authority, of which the London Assembly is part. A consensus eventually grew around the use of AM.

[uni-29] The exact post-nominals for degrees vary between courses and between universities, common ones are shown here, ordered according to the Framework for Higher Education Qualifications.^[12]

[46] Use of Cantuar for Kent is rare and risks confusion with both Lambeth degrees and the University of Canterbury, NZ. The Latin name for Kent is Cantium (hence Cantiensis) which would give Cant (also used by the University of Canterbury, NZ); the University of Kent was originally the University of Kent at Canterbury.

[59] Awarded to undergraduates who receive a BEng or MEng degree from a programme within the City and Guilds College-Imperial College London.

[64] Debrett's previously added that: "Strictly speaking, [Learned Societies] should be arranged according to date of foundation or incorporation of the societies concerned, but some hold that those with a Royal Charter should take precedence."^[44] This has been deleted from the current advice.

[68] I.e. by what they are a society or institute of or for, e.g. Aeronautical for the Royal Aeronautical Society. Bodies without a substantive name, such as the Royal Society, are listed at the top, ordered by their full names.

[71] While based outside the UK, the RIA is an all-Ireland learned body covering Northern Ireland

[73] Used only within the society

[78] Fellows who were fellows of both the Institute of Actuaries and the Faculty of Actuaries prior to their merger may continue to use both FIA and FFA

[104] No post-nominals are assigned by the society in its regulations;^[75] the use of the post-nominal letters FRAS is however recognized by many reference works.^[76]^[77]^[78]^[79]

[111] Note the President uses the statement "President, RIBA" but does not gain specific post-nominals

[133] May be used in correspondence, etc., but not in screen credits

[166] Not a Privy Council approved individual chartered designation^[138]

[167] Issued jointly with the American Institute of Certified Public Accountants and used alongside FCMA or ACMA by CIMA members

[211] According to Debrett's and Black's, listed after fellowships of learned societies, royal academicians, and memberships of professional bodies. Debrett's lists Writers to the Signet before MPs, while Black's lists them together.

[rank-243] "RN" or "RNR" is used for officers with the rank of Commodore or below.

[army-244] In the Army, the initials of the regiment or corps of the officer are used as post-nominals. Until 2015, those above the rank of Lieutenant Colonel had their former regiment or corps preceded by the word 'Late', representing their elevation to the General Staff. This practice was abolished by order of the CGS with effect from 1 Apr 15, but remains in usage amongst those who retired prior to this date

[raf-245] "RAF" or "RAFVR" technically should be used for officers with the rank of Air Chief Marshal and below, though, in practice, it is used for officers with the rank of Wing Commander and below.

[nurse-258] The title of "1st Level Registered Nurse" is comparable to the old titles of RGN, RMN etc. The title of "2nd Level Registered Nurse" refers to those previously called Enrolled Nurses. The post-nominal letters for 1st Level Registered Nurses can be used interchangeably but not together i.e. either Your Name, RN1 or Your Name, RNA not Your Name, RN1, RNA
