From a landline in the United States, Canada, etc., dial 1 + area code + number.
From a cellular phone in the US or Canada, you can usually dial just area code + number.
From a GSM mobile phone, anywhere in the world, dial +1 and then the area code and number, including the plus symbol.
Otherwise, dial your international access prefix (most commonly 00), then country code 1 and the area code and number.
(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 Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
