There are also a lot of edge cases where I've found it doesn't work. Phone numbers change all the time, so if you are using this library you need to update it constantly, and even then it may still be outdated for new changes. If I need to validate a phone number is correct I'll send an SMS and ask the user to enter a code, otherwise I'll assume they know their phone number better than me.
