US addresses can yield latitude and longitude, area code, time zone, and daylight savings information as an optional return. CDYNE's PAV API returns the 'from' longitude and latitude and the 'to' longitude and latitude. It can also return the average latitude and longitude, and the time zone that the address is in. It will also return whether the address has Daylight Savings time along with the area code for that location.
CDYNE's PAV API includes geo location data as part of its Postal Address Verification solution.
