List of counties in Alabama

The state of Alabama has 67 . Each county serves as the local level of government within its borders. The land enclosed by the present state borders was joined to the United States of America gradually. Following the American Revolutionary War, West Florida was ceded to Spain by treaty while the remainder was organized primarily as the Mississippi Territory, and later the Alabama Territory. The territorial assembly established some of the earliest county divisions that have survived to the present, including the earliest county formation, that of Washington County, created on June 4, 1800. In 1814, the Treaty of Fort Jackson opened the territory to American settlers, which in turn led to a more rapid rate of county creation. Alabama was admitted to the Union as the 22nd state in 1819. The Alabama state legislature formed additional counties from former Indian lands as the Indian Removal Act took effect and settlers populated different areas of Alabama. In 1820, Alabama had 29 counties. By 1830 there were 36 and Native Americans still occupied large areas of land in northeast and far western Alabama. By 1840, 49 counties had been created; 52 by 1850; 65 by 1870; and the present 67 counties by 1903.Foscue, Virginia O. (1989) Place Names in Alabama. Tuscaloosa, Alabama: University of Alabama Press. ISBN 081730410X Houston County was the last county created in the state, on February 9, 1903.
According to 2010 U. S. Census data, the average population of Alabama's 67 counties is 71,399, with Jefferson County as the most populous (658,466), and Greene County (9,045) the least.  The average land area is 756 sq mi (1,958 km2). The largest county is Baldwin County (1,590 sq mi, 4,118 km2) and the smallest is Etowah County (535 sq mi, 1,386 km2).  The Constitution of Alabama requires that any new county in Alabama cover at least 600km2 in area, effectively limiting the creation of new counties in the state.
The Alabama Department of Revenue's Motor Vehicle Division issues standard automobile license plates that bear a one- or two-digit number identifying the county in which the vehicle is registered. This number is given in the fourth column in the table below. The first three prefixes are reserved for the state's historically most populous counties, and thereafter proceed alphabetically. Individual license plate numbers are assigned sequentially in each licensing office. The numbers are in the format XA1111A or XXA111A, depending on whether the prefix is one or two digits.  Overflow registrations are accommodated by substituting a letter for one of the registration numbers, such that XXZ999Z is followed by XXA0A0A.
The Federal Information Processing Standard (FIPS) code, used by the United States government to uniquely identify counties, is provided with each entry. The FIPS code links in the table point to U. S. Census "quick facts" pages for each county.
