Perhaps they should read this: https://news.ycombinator.com/item?id=19214035 https://news.ycombinator.com/item?id=19214035 Phone numbers are something you dial into a phone. They are not a alphabetic ISO code and then some numbers. Country codes and international dialing codes are NOT 1:1. North Korea for example has two dialing codes but is one county. Many island nations share the US's +1. Staphones have their own dialing prefixes that don't correspond to an ISO country code. With all due respect, this code is a disaster and it is guaranteed to lead to problems when one of these many edge cases is hit.
