Conn.

Geography & Places abbreviation · US State Traditional

Conn. stands for Connecticut, a US state traditional abbreviation.

Connecticut's abbreviation in AP style, the GPO manual and The Bluebook, found in datelines (NEW HAVEN, Conn.), in labels such as D-Conn., and in citations to the Connecticut Reports. Its double n mirrors the start of the state name, making it easy to recognize.

Example: STAMFORD, Conn. — A signal problem delayed trains on the New Haven Line during the morning rush.

Usage notes

Connecticut's postal code is CT, not CN or CO, which trips up many people; Conn. is easier to recognize but belongs only in edited text. The silent middle c in Connecticut is a frequent spelling error that the abbreviation sidesteps.
