Ask your local phone company.
That depends on your wireless carrier (cellphone company) or your local telephone company (for a landline phone).
Dial the full number - including the area code.
From a landline, dial 00 1 and then the area code and number. From a mobile phone, dial +1 (including the plus symbol) and then area code and number.
If you have only the 7-digit number for a cell phone number in an area with more than one area code, there is no way to determine which area code it belongs to, other than guessing. In particular, in the United States and Canada (except for numbers in area code 600), cell phones use the same geographic area codes as landline phones, and in all cities and even most rural areas, you can take your telephone number with you, even switching from cellular to landline or vice-versa.
To forward telephone calls from a landline to a cell phone line, follow these general steps, which may vary depending on your service provider: Dial the activation code provided by your landline service provider (such as *72) on your landline phone. Enter the phone number of the cell phone where you want calls forwarded. Wait for a confirmation tone or message indicating that call forwarding has been set up. Test the call forwarding by making a call to your landline; it should be forwarded to your cell phone. Note: To deactivate call forwarding, dial the deactivation code provided by your landline service provider (such as *73) on your landline phone.
Your phone or Caller ID unit is probably programmed to display numbers in the same area code with just the 7-digit number. On most units, you can change that setting. Check your user manual.
It is quite common in the U.S. for a person to have a cell phone with an area code from somewhere other than where they currently live. To have a landline with a different area code is much more difficult and expensive.

US cell phone numbers are indistinguishable from landline numbers. They use the same geographic area codes, and calls are billed at the same rates. The telephone country code for the USA (plus Canada and certain Caribbean-ish islands) is +1. On a mobile phone, just dial +1 (including the plus symbol) and the area code (3 digits) and number (7 digits). On a landline, dial 00 1 and the area code and number.
The 360-473 prefix is in Bremerton, Washington. There's no way to know if a particular number is a cell phone or a landline. Local number portability means that you can change from a cell phone to a landline, or vice-versa, and keep the same number.
