The state abbreviations are as follows: AL for Alabama, AK for Alaska, AZ for Arizona, AR for Arkansas, CA for California, CO for Colorado, CT for Connecticut, DE for Delaware, FL for Florida, GA for Georgia, HI for Hawaii, ID for Idaho, IL for Illinois, IN for Indiana, IA for Iowa, KS for Kansas, KY for Kentucky, LA for Louisiana, ME for Maine, MD for Maryland, MA for Massachusetts, MI for Michigan, MN for Minnesota, MS for Mississippi, MO for Missouri, MT for Montana, NE for Nebraska, NV for Nevada, NH for New Hampshire, NJ for New Jersey, NM for New Mexico, NY for New York, NC for North Carolina, ND for North Dakota, OH for Ohio, OK for Oklahoma, OR for Oregon, PA for Pennsylvania, RI for Rhode Island, SC for South Carolina, SD for South Dakota, TN for Tennessee, TX for Texas, UT for Utah, VT for Vermont, VA for Virginia, WA for Washington, WV for West Virginia, WI for Wisconsin and WY for Wyoming.
