Ten-Digit Dialing Reminder

Don't forget, for those times when you're not making a call using one click with Skype for Business, ten digits are required when dialing Ohio State phone numbers (area code + ###-####) and the same ten-digit phone number for long distance calls. You will not need to prefix numbers with a 9 to dial off campus. The previously used five-digit campus shortcut dialing is no longer supported.

If you have questions or need assistance, please contact the IT Service Desk by calling 614-688-4357 (HELP), emailing servicedesk@osu.edu or visiting Self Service.
