Area code 314 serves the city of St. Louis, Missouri, and most suburbs in St. Louis County.
Area code 636 acts as an envelope around the 314 coverage area. Area code 314 was split in 1996 to create area code 573, and was split again in 1999 when the outer suburbs were assigned area code 636.
East St. Louis, Illinois, and other suburbs in Illinois, are in area code 618. Area code 730 will be added as an overlay on 618, probably in 2014 or 2015.
The USA uses telephone country code +1.
(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
That depends on your phone company and calling plan.
If you are calling from a landline in area code 314 (St. Louis, Missouri, area), try dialing the call with just the area code and number (i.e., do not dial 1 first). If the call goes through, it's a local call; if not, you will get a recording telling you to hang up and redial with the '1' prefix for a toll call.
(The above advice applies to many parts of the US and most of Canada, including Missouri, but does not apply to some places including California, New York, and Illinois, among others. It also does not apply to mobiles/cellphones.)

Area codes 314 and 636 are adjacent, so it is likely that many calls between them are local, but there may also be some toll calls.The easiest way to find out is to dial the number with just the area code and number (without the "one plus" at the start). For example, dial just 314-555-0123. If the call goes through, it's local. If you get a recording telling you to hang up and dial 1+, then you know it's toll. (This works in Missouri and many other states, but not in some other states like CA, NY, IL, etc.)
In areas with "toll alerting" (you must dial 1+ for all toll calls), you must dial 1+area+number even if the area code is the same. Many cell phones require you to dial the area code and number to prevent confusion with other nearby area codes. In overlay areas, you must always dial the area code. In some overlay areas, you can dial just the area+number for local calls; in others, you must dial 1+area+number for all calls, local or toll.
Area code 314 is St. Louis, Missouri, plus a few close-in suburbs. LATA 520 is designated as the St. Louis LATA. It includes all of area code 314, plus all of area code 636 (St. Charles, MO), a large part of area code 573 (but not Columbia or Jefferson City, MO), and part of area code 618 (East St. Louis, IL). A LATA is a Local Access and Transport Area. After the break-up of the AT&T system, your local telephone company (in most cases, one of the "Baby Bells") had a monopoly on all calls within your LATA, but had to hand off calls to other LATAs to a long-distance company. In more recent years, telephone competition has expanded to include intra-LATA calls.
The 636 area code is used by the state of Missouri. It generally applies to the eastern and central areas of Missouri - other area codes used by the state include 314, 417 and 573.
