Application numbers are 8 digits long (99/999999). The first two digits are a series code and the last six represent a serial code assigned by the USPTO. The histpatent table has over 3 million application numbers with 7 digits, since leading zeros were dropped. Leading zeros were also dropped for patent numbers.
