It is very easy for an unscrupulous telemarketing company to "accidentally" mis-program its telephone switchboard to send nonsense for Caller ID data.
Yes.
Depending on what you mean by "the area code of a call," it's either the area code of the phone you're calling from or the area code of the phone you're ringing. The fact that the call is "collect" (reverse charges) is irrelevant.
Since area code 656 does not exist, it has no Division 1 colleges.
Area code 808 is Hawaii. Area code 301 is in Maryland. Unless you have nationwide long distance included in your calling plan, there will be a charge for that call.

The same local telephone number can exist in many different area codes. (After all, that's the whole point of area codes.) If you know where the telephone number is from, and if that place has only one area code, you can find out that way.
It does not exist as a cheat code
Sorry, area codes are only assigned to places that exist.
When an area code splits, some of the telephone numbers change to the new area code. There is a period of permissive dialing in which calls placed using either the old or new area code will complete. After permissive dialing ends, calls placed using the old area code will receive a recorded message instructing the caller to redial using the new area code. When that recording is disconnected, calls made using the old area code will fail, or will reach a wrong number.
It depends on your long-distance company and calling plan. Area code 203 is in Connecticut, and area code 507 is in Minnesota.
Not unless there is a glitch in the system. Area code 214 is Dallas, Texas; area code 225 is Baton Rouge, Louisiana.
The area code "029" is assigned to the city Cardiff in Wales, UK.
