The CDP of Stanford is mostly made up of Stanford University. Stanford is an unincorporated part of Santa Clara County and is adjacent to the city of Palo Alto. Stanford, California is a valid postal address, and has its own post office and zip codes: 94305 (campus buildings) and 94309 (post-office boxes).
For years, mail sent to Stanford, CA would be redirected to Stamford, Connecticut because the Post Office assumed the then-non-existent address was a misspelling.
