Call the USA from South Korea
Call a US friend, university, office or business from South Korea. Start with the city and date at the other end, then confirm the full +1 number and its rate.
Seoul and the USA may be on different dates
A morning in Seoul can still be the previous day in the USA. The live clocks show the local date as well as the hour so a family arrangement or business appointment does not slip by a day. Check the selected office's own opening schedule too.
Use one international format in your browser
Enter +1 followed by the three-digit US area code and seven-digit local number. Do not add a Korean carrier-selection prefix to that browser format. Ask a US business for its full international contact number if you only have a short code or internal extension.
US international number format
+1, then the three-digit area code and seven-digit local number. Check the full number and current rate before calling. Other countries share the +1 code, so confirm the destination is identified as the USA.
Questions before you call
How do I avoid calling on the wrong US day from Korea?
Check the date displayed beside the US city's clock, not only the time. Confirm appointments using the recipient's US date and city as well as your Seoul date.
