Chicago Campus Mail Codes

The mail code system increases sorting speed and reduces errors. Like zip codes on U.S. mail, campus mail codes are the primary factor determining where a piece of mail is delivered.

The Chicago campus mail code is alphanumeric and should appear next to the department or division name on your stationary.

There is no need to add a line for the mail code to your return address on letterheads, envelopes, and business cards as long as the correct alphanumeric code appears as part of the address. When giving your address to someone on campus, please include your mail code. Also, please use the mail code when addressing campus mail. Most campus mail envelopes have a line in the address block for this purpose.

Campus mail codes are listed below by street address and within each address, by department. To find a location not listed here or for any questions concerning use of the campus code, please contact Tom Luczkowiak, Mail Services Manager, at 847-491-8411.
