Four digit campus mail codes are managed by Mail and Delivery Services (MDS),
in coordination with the School of Medicine's Mailroom.

Please use this page to review or search the mail code file.

If you anticipate a change in the location of your mail stop, please contact us.
Many times a change in location will require the assignment of a new mail code.
Please do not make up or assign your own mail codes!

Please also note that campus mailcodes are different from the US Post Office Zip+4 system. To view the USPS Zip+4 code for your address click here.

Mail codes are grouped into either the University Departments( UNIV) or the Medical Center departments (SMC).

Please direct requests for new mailcodes to: mailroom@bonair.stanford.edu.
