Change of Address Posted on September 8, 2022 To change your legal address with the College, complete a Change of Address/Certificate of Residency form, available online at gcc.mass.edu/registrar/forms. If address is being changed to Massachusetts, the certificate of residency portion of the form must be completed. GCC may require proof of residency.
