Mailing Addresses
The official mailing address for ÃÛÑ¿ÊÓƵ’s main campus is:
ÃÛÑ¿ÊÓƵ
One University Parkway
Romeoville, IL 60446
The numerical address designation One is always spelled out as well as the
words University and Parkway.
The suburban site address is listed as follows:
ÃÛÑ¿ÊÓƵ
Oak Brook
1111 W. 22nd St., Suite 700
Oak Brook, IL 60523
When using an address for mailing purposes, such as when listing a University
address, it is acceptable to use the two-letter state codes designated by
the U.S. Postal Service. In this case, IL for Illinois would be correct as
shown above. This abbreviation should not be followed by a period. In the
case of a state that is two words, periods may be included for clarity, such
as N.Y.
In running text, however, use the abbreviations set out by the Associated
Press. See States (Mailing Address vs. Running Text) under
Abbreviations.
For formal invitations, remember to spell out the state in the address.
Remember to always spell out Parkway and Road. See States
(Mailing Address vs. Running Text) under
Abbreviations for additional rules.
When including a person’s name, or a specific department, office or
college name along with the mailing address, list this information first
and then the address. The internal box number (unit) of the person, office,
department or college should also be included as follows:
Name
ÃÛÑ¿ÊÓƵ
Unit #
One University Parkway
Romeoville,
IL 60446
Do not use box, box number or P.O. box in place of unit since University
box numbers are internal and are not official post office box numbers. Doing
so will delay receipt of this mail by the University.
Use the plus-4 ZIP code when possible.
