In 1950, Indiana established county codes for license plates, which were designated with 2 letters followed by up to 4 numbers. The oldest counties are generally located in the south, near the Ohio River, while the newer ones are in the north, in territory acquired later. This can be seen in smaller counties that only need fewer than 30,000 license plates and used the letters “A”, “B” and “C.
After the county number there was a single letter (which normally represented the BMV branch within the county) and possible 9,999 plates per county number and branch letter. The coldest temperature ever recorded in Indiana occurred in the town of New Whiteland, Indiana, on January 19, 1994, when the temperature reached −36 °F (−38 °C). The average monthly rainfall ranged from 2.05 inches (52 mm) in January to 4.78 inches (121 mm) in July. In recent years, average temperatures in Franklin have ranged from a low of 18°F (−8°C) in January to a high of 84°F (29°C) in July, although an all-time low of −22°F (−30°C) was recorded in January 1985 and an all-time high of 104°F (40°C) in June 1988. Many of the final counties were formed after the acquisition and dissolution of the Miami Grand Reserve (which encompasses present-day Howard County and parts of the surrounding counties) between 1834 and 1840.
In Indiana, the most common number associated with counties is the state's county code, which is a sequential number based on the alphabetical order of the county.
