Should cell/mobile phones have their own area code numbers?

Question

With the massive amount of cell phones and other related devices,
wouldn't it have been better if these devices had their own designated
area code numbers? Every so may years, certain areas all around
the country have to change their area codes because they run out
of phone numbers. Also, cell phone companies have been known
to buy thousands of phone numbers in blocks at a time, thus
depleting numbers even more for area residents, companies,
businesses,etc.

Answer 1

The area code is determined by where the phone is "based". Cell phones do have their own exchanges though. This is also represented by where it is based. For example, in my area the exchange 797 is owned by Verizon Wireless, so you will never see a landline in my area using 797.

Answer 2

we would run out of area codes

Answer 3

no
