LoL Hope nobody ever gets that number
555 numbers are all fake. There is no 555. That's reserved and they use it as example numbers or numbers in media - like fake numbers in movies and television. So, there's no 555 - with one exception and I'm not sure if it's still true. The number I had out was once the number for information/directory services. That was <your area code> 555-1212. I hand that one out frequently.
Someday they may need those numbers
I doubt it. They just add new area codes. Lemme do some math...
Every 3 digit area code can have ~8 million numbers. There are 999 combinations - minus some reserved numbers like the 555 numbers and the 800 numbers. (Those will be trivial in the results.)
There are just a touch less than 8 billion possible numbers.
That's BILLION. That's a bit less than the total global population. If they need to, they'd either increase the area code's number of digits or add another digit somewhere. But, it's gonna be a long, long time before they need 8 billion numbers in the US - and Canada. (Canada shares the system with us, which is why you can call Canada for free, often times, and why you don't need to dial a country-code when calling Canada, unlike when you call every other country. We have no such agreements with anyone else, just Canada.)
So, we're gonna be fine for a long, long time.
Eventually, we may not even use real numbers to connect to others. So, there's also that aspect.
