Address Book Interop: Correct Phone No format

Hi,

We intend to use JDE Address Book Z processing for some Address Book phone records. There are some suppliers who have toll free and other numbers like 1300......, 1800....... and some others who are international suppliers and have numbers like +64 456 .............. Would it be OK to use the prefix field for that as per attached excel. My concern is that since the prefix field has some special characters like underscore (_), add (+) etc, would it be OK to have these values in there at the time of Z batch report processing? Thank you,
