What is the difference between a personal lines license and a property and casualty license?

A property and casualty license covers the full property and casualty lines, including commercial risks such as general liability. A personal lines license is narrower: it covers property and casualty insurance sold to individuals and families for primarily noncommercial purposes, such as personal auto and homeowners policies. In some states, including California and Illinois, the two are separate license tracks, so a property and casualty licensee may need an additional application to add personal lines.
