The FAAT List is a handy reference for the myriad of acronyms and abbreviations used within the federal government, emergency management and first response communities. This year's new edition, which continues to reflect the evolving U.S. Department of Homeland Security, contains an approximately 50 percent increase in the number of entries and definitions bringing the total to over 6,200 acronyms, abbreviations and terms. Some items listed are obsolete, but they are included because they may still appear in publications and correspondence. Obsolete items can be found at the end of this document.
FAAT List users are encouraged to submit acronyms or abbreviations not listed in the current edition by sending them to FAAT@dhs.gov.
