Add or change phone numbers

Your phone numbers show up on your contact card and are visible to your contacts, depending on the permission you choose when adding them.

  1. Under My phone numbers click a box and type your number. Use only the digits 0123456789, and no parentheses or hyphens. When adding international numbers, type the + sign, then the country code followed by the local number.
  2. Check the boxes next to the numbers that you want to show on your contact card.
  • Work Phone: is visible to all contacts except blocked or external contacts. If your campus directory entry has your work phone number, this option will be grayed out and it won’t let you change the number or remove from your contact card, even if you uncheck the box next to Include in my contact card.
  • Mobile Phone: is visible only to contacts with Workgroup or Friends and Family permissions.
  • Home Phone: is visible only to contacts with Friends and Family permissions.
  • Other Phone: this option is set by the Skype for Business server and cannot be modified.  It is visible only to contacts with Friends and Family permissions.
