Question

iPhone has a pretty good telephone number splitting function, for example:

Singapore mobile: [phone]
Singapore resident line: [phone]
China mobile: [phone]
China resident line: [phone]
HongKong: [phone]
USA: [phone]

Notice the nice features here:
– the splitting of country code, area code, and the rest is automatic;
– the delimiter is also nicely adopted to different countries, e.g. “()”, “-” and space.

Note the parsing logic is doable to me, however, I don’t know where to get the knowledge of most countries’ telephone number format.
where could i found such knowledge, or an open source code that implemented it?

Answer 1

You can get similar functionality with the libphonenumber code library.
