Where are you getting the phone numbers from? If you're getting them from part of the phone network, you'll get a string of digits and a number type and plan, eg

441234567890 type/plan 0x11 (which means international E.164)

In most cases the best thing to do is to store all of these as they are, and normalise for display, though storing normalised numbers can be useful if you want to use them as a unique key or similar.
