We automatically format numbers for you. You can set the default country under:
SMS -> settings -> default country code
This means you can supply a number in local or international format and we'll automatically format it.
If you're sending via our API, you can also supply the 'country' parameter (optional). This will let you supply a phone number in any format, including local format for any country. Simply add the 2-character iso country code e.g. country="US".
