1 usually signifies a long distance call. It also is prepended to all
calls using the full 10 digit areacode + exchange and number. 

So it is possible in the USA to dial a 7 digit number without a 1
prepended for local calls in some areas. It is possible for some 7 digit
numbers to be long distance(toll) and require a 1 to be prepended to the
7 digits as a acceptance of the extra charge. All 10 digit dialing is
done with a 1 prepended.
