A correct dateline should include "a city name, fully in capital letters, followed in most cases by the name of the state, county, or territory where the city is located," according to the AP Stylebook. The city name should also be included in quotation marks if it's a person or entity other than the United States government. Datelines use two elements in alphabetical order: a location name and a region name. The location name is usually a city, but it can be a town or other area name as well. The region name is usually a state or province name, but it can be another type of organization such as NATO (North Atlantic Treaty Organization). If the city or town has no specific name, such as "Los Angeles", then the location name will need to provide context about what kind of place it is. For example, if it's a university, then the location name could be referred to as "University Park". If it's a small village, then the location name could be simply written as "Pennsylvania". The best way to find the appropriate state or provincial name is to look it up on a map. If you don't have a map available, then you can search online for "country name region name city name" to see if any results come up.
