About the Acronym Finder

The Acronym Finder is a searchable database of more than abbreviations and acronyms about computers, technology, telecommunications, and the military. Over the years, the site has received numerous awards.

Acronym Finder is not a glossary of terms, web search engine, or dictionary or a thesaurus -- it is only designed to search for and expand acronyms and abbreviations. If you need more information about a word or other reference topic, we highly recommend

See Search Tips for information about using the site, including advanced search techniques.

If you don't find an acronym or abbreviation in the database, but know its meaning, you may suggest it be added here. If it meets our guidelines, it will be reviewed, verified, edited, and added to our database in our next update (usually several times a week).

What's an Acronym?

An acronym is a pronounceable word formed from each of the first letters of a descriptive phrase or by combining the initial letters or parts of words from the phrase. Here are some examples of acronyms:

North Atlantic Treaty Organization = NATO
MODulator/DEModulator = MODEM

An acronym is actually a type of abbreviation. Our database contains abbreviations, acronyms, and initialisms and we make no distinction between them in our database or on our site. We are more interested in defining "acronyms" for you than we are in trying to properly distinguish between abbreviations, acronyms, and initialisms.

Though you sometimes see acronyms or abbreviations written with periods after each letter (e.g., U.S.A.), we don't use that form here. When entering search terms, don't include the periods (unless the acronym normally contains a period, i.e., X.25).
