Expansion to four-digit area codes is already provided for in the North American Numbering Plan (NANP).  All existing area codes would have 9 added in between the first and second digits (notice no current area codes have 9 and the second digit).  That would provide for a 10x expansion to over 6,000 area codes within the NANP.

The issue would remain, of course, that a lot of US-based software only has room for ten digits.

Which makes such software unusable even in Mexico or EU. Of course, not a problem for domestic-only things.
SSN may be another numerical ID with the same set of issues - low capacity of the system and rigid notation.

Bolded portion especially true.  A US company who only does business with customers within a 300-mile radius has no need for software that doesn't assume 123-456-7890 telephone number format.

Incidentally, the computer programs I use at work assume that format.  You just type "5254545656" and it outpurs "525 454-5656".  These are programs provided by the phone company.

What happens if you put in a phone number with other than 10 digits? It may well simply have a if(input.length == 10) { input.insert_space(3); input.insert_dash(7); } block.

I commonly see just the first 10 digits shown. Annoying if 1 was used first.
