General guidelines

Abbreviations, including acronyms (e.g. UNESCO), should be used sparingly. In certain formal contexts, such as General Assembly resolutions, they should not be used at all.

When they are used, abbreviations should always be explained. The name or title should be written out in full the first time it occurs in the main body of a document, followed by the abbreviation in parentheses. Thereafter, the abbreviation may be used in footnotes, figures, tables and boxes. If an abbreviation first appears in a footnote, figure, table or box, it should be written out in full again the first time it is used in the main body of the document.

Alternatively, if a document contains numerous abbreviations, a list may be included after the table of contents or at the end of the document if there is no table of contents. A list of abbreviations applies to the main document and to any annexes or attachments to it.

In United Nations publications, a list of abbreviations, if required, is normally included in the explanatory notes.

Abbreviations are not used for names or titles that occur only once or twice in a text. When the entity referred to is better known by the abbreviation (e.g. Habitat III, UN-Habitat and UN-Women), it may however be preferable to include the abbreviation even if the name occurs only once.

The most common units of weight and measure, such as cm², kg and km, need not be written out.

Abbreviations are not used in document titles or headings.

"United Nations" should not be abbreviated in English. The form "ONU" is acceptable in French.

In United Nations style, abbreviations are written without full stops: UNDP, not U.N.D.P.

Abbreviations must not be used with the definite article: the members of UNESCO, the programmes of WHO, except when they are used adjectivally: the IMF report, the NGO coalition.

Abbreviations should not be used in the possessive form: the Commander of UNMIL or the UNMIL Commander, not UNMIL's Commander.

Forms of address such as “H.E.” or “His Excellency” and “H.R.H” or “Her Royal Highness” should not be used in United Nations documents. The title “Dr.” may be used for doctors of medicine acting in a medical capacity.


	Abbreviations should not be used for the following (although short titles may be used where appropriate):

	Principal organs and major offices of the United Nations: General Assembly, Security Council, Economic and Social Council United Nations Office at Geneva/Vienna/Nairobi
	Titles of senior officials: Secretary-General, Under-Secretary-General, Special Representative of the Secretary-General

	Most commissions and committees, boards, panels and the like
	Conventions, treaties, plans/programmes of action
	Non-technical terms and concepts in widespread use, such as "the rule of law", "human rights", "human resources" and "sustainable development"
	Funds, programmes and the like that are not established as organizations
	Names of Member States
	General Service (Principal level, Other level, Local level)
	The International Criminal Court (to avoid confusion with organizations such as the International Chamber of Commerce)
