Here's a list of all ARRL sections, along with their proper abbreviations, used in our contests. You use these abbreviations in the lines of QSO data for contests that require a section as part of the exchange (Sweepstakes and 160 Meter Contest, plus Field Day).
You also use these abbreviations in your Cabrillo log header for your LOCATION: or ARRL-SECTION: tag in all ARRL contests.
A printable version of this list is available here.
