And it would be trivial to provide functions to map that into the
customary format for various countries. In fact, since there's 4 bits
left over, it might be possible to encode the formatting used for the
number in the storage itself.

BTW, you sure about 68 bits? That doesn't seem to allow for a full 20
digit number; or are there restrictions on the max value for one of the
fields?
