The US did not create new area codes for cell phones. I kinda wonder if it would have ever worked. There are only like 800 of them available to the whole nation. 000-199 are not usable; neither an area code or an exchange can start with a leading 0 or 1. And certain round numbers and easy to remember area codes like 200, 211, 300, 311 etc. are reserved. 411 for example is the infromation service, 911 is the emergency number. Fun fact: cell phones are required to be able to dial 911 even if they don’t have a plan or number associated to them. If you dial 911 from a disconnected cell phone, the system will randomly assign that phone a number with a 911 area code.
Even though you can carry a phone elsewhere with you, they are still “area codes.” If you get a new cell phone, it will be assigned an area code for the area you purchased it in. People have moved around and kept their familiar numbers, which is what this XKCD comic is referring to.
The next three digits are the “exchange,” which once upon a time was also routable. Everyone in the same town or neighborhood might have the same exchange, so at one point you really only had to remember 4 digits for a particular phone number, because you knew what exchange and area they were in. Especially with cell phones it’s pretty much 10 random digits.
