I have looked everywhere concerning the styles format for phone numbers. Here is my situation: I am writing a letter and want to use this format "Text # xxx-xxx-xxxx" as part of the address/email heading. I am hearing impaired (hard of hearing) and want people to "understand" that it means to text me by phone. So, I am leaning toward to using this: "xxx-xxx-xxxx SMS/Text only" or "Text/SMS #: xxx-xxx-xxxx" The Chicago Style, AP Style or the Manual Style doesn't have something of that sort, so any help or suggestions will be much appreciated.
