Can I use abbreviations for state names?

Yes, you may abbreviate state names. However, before manually adding a state (or province) you should check whether the state already exists in the database. (Hint: If you enter the country first, the corresponding states, if available, will appear.) For example, the default list of states for the United States uses the standard two-letter abbreviations. New York appears as NY and Virginia appears as VA in the list of U.S. states.
