Stanford University will not issue duplicate diplomas under any circumstances. This measure is taken to protect Alumni from identity theft. If your diploma was permanently lost or destroyed, a replacement diploma may be ordered from the Office of the University Registrar. You must fill out the Replacement Diploma Form (pdf), have it signed by a Notary Public, and send it in with a check for the fee amount listed on the form. From the time of receipt of the form to issuance of the replacement takes 4-6 weeks.
Each replacement diploma follows the current diploma format and includes a notation stating that the diploma is a replacement of the original and listing date of its preparation. All replacement diplomas bear the signatures of the current University Chair of the Board of Trustees, President, and School Dean.
