Distinguishing Cambridge from Neighboring Codes
It is common for people to confuse the postal boundaries of Cambridge with neighboring cities like Boston. While 02138 is firmly rooted in Cambridge, the area just across the river might fall under the 02128 Boston code.

The Role of Zip+4 Codes
For maximum precision, the standard 02138 can be expanded into a Zip+4 code, which adds four additional digits to pinpoint a specific building or group of addresses. This extended format is particularly useful for high-volume mailers and universities managing large volumes of correspondence. If you are sending mail to a specific department at MIT or a particular law school dormitory, utilizing the Zip+4 system ensures your item arrives without delay or confusion in the complex campus environment.
