Let's see how that would work with my phone number:
+31 10 75 01888 991
| | | | |
| | | | extension
| | | number
| | prefix
| area code
country code
And this is even shorter then the maximum allowed length for a
phone numer (15 digits according to ITU-T E164).
Typically I store telephone numbers in a domain with the
following definition:
CREATE DOMAIN phonenumber AS VARCHAR(20)
CHECK (VALUE LIKE '+_% _% _%');
