libphonenumber

What it is

Google’s libphonenumber carries the numbering plan of every region: which numbers are valid, how they are written, which line type each range is, the original network of many mobile prefixes, the places geographic ranges serve, their time zones, and emergency and short numbers. It ships with the application; every answer names its version.

What the copy installed here holds

The metadata ships with the application; its release is named in every answer.

How it is read

Not a table of blocks: it answers whether a number is valid for its plan and which line type its range is.

• Its carrier names come from prefix data and name the range’s original network, never the one serving a ported number.
