  • Last name only
  • First initial, middle initial, last name
  • First two letters of first name, last name

Can I change my Cal Poly username?

Only in very rare cases, might a user get a new username. Changing a username requires manual intervention and takes substantial time and effort to ensure that it is changed in all applicable campus systems.

ITS will only change a username if:

  • An individual's legal name is changed.
  • The assigned username represents a credible danger to the health or safety of the individual.
  • The username spells out a word considered inappropriate or offensive to the individual or the university.

Any other exceptions must be approved by the ITS Office of the CIO.
