<p>In the new student info packet it says the mailing address for mail is:</p>
<p>Name
Incoming Student
California Institute of Technology
Pasadena, CA 91126</p>
<p>Is it really 91126 rather than 91125, or is this a typo?</p>
<p>It really is 91126, for mailing stuff it's 91126, and the physical address is 91125.</p>
<p>91125 is for the mail codes for the offices and stuff on campus. Undergrad mail (all the MSC #'s) need to be addressed to 91126.</p>
<p>Yup, Caltech undergrads get their own unique zip code, now don't you feel special?</p>
