Understanding Dialing Instructions for Calls to and within the US

• Outside the USA: When you are making a phone call to a number in the USA from outside the country, you need to start with the country code "+1". The "+1" is the international dialing code for the USA.
• Inside the USA: When you are making a phone call to a number within the USA from another number within the USA, you do not need to include the "+1" country code. You can simply dial the 10-digit local number.

In summary, the presence of "+1" depends on whether you are dialing internationally (from outside the USA) or domestically (from within the USA).
