Template:Area code list

How to manage this template's visibility

• Use {{Area code list |state=collapsed}}  to show this template in its collapsed (hidden) state.
• Use {{Area code list |state=expanded}}  to show this template in its expanded (fully visible) state.
• Use {{Area code list |state=autocollapse}}  to show this template in its collapsed (hidden) state only if there is another template of the same type on the page.
• Unless set otherwise (see state parameter within the template's code), autocollapse is the default state.

Usage

This macro is placed on the primary listing page for all the area codes in each state or country in the North American Numbering Plan. If there is more than one area code for a state, it should link the state to a page such as [[List of Idaho area codes|Idaho]]. Where there is a page listing all area codes for that state or country, each area code listed on it should point back to the state's area code list page. If there is only one area code for the country or state, then it is placed on that area code page, e.g. [[Area code 302|Delaware]].
