What is my login name and email address?

Penn's centrally operated email servers are PennNames compliant servers so your login name (also known as a "username") will be the same as your PennName (your unique University username) upon which your PennKey is based. While you do not need to have a PennName before creating a new account on our email servers, you do need to first have a record in PennCommunity, the central University data store. User records are loaded into PennCommunity by:
  1. Registrar load of students
  2. Payroll load of employees
  3. UPHS load of employees
  4. Manual submission of a Guest record by your department's PennCommunity administrator

Your email address is your login name combined with your domain name joined with the @ ("at") symbol. Since there are multiple domains hosted on these email servers, you may have a number of possible email addresses.

Following are recommendations that ISC makes for which email address you should use. Please check with your LSP or account administrator to see which email address is preferred by your department. It is most important that your email address match expectations of other users on the system. If another user is trying to find calendar information for you, he/she may not be able to find it if you are listed in the Global Address List (GAL) as and your correspondent is looking for info for
