How to Address a Member of a
City or County -- Council or Board

Councilmen and councilwomen are roles filled by citizens on a a town, city or county council. The position can be either elected or appointed.
Counselor, counsellor, councilor or councillor are spelling used in Great Britain, Canada, Australia, South Africa, and other parts of the Commonwealth, and sometimes in the United States. They have the advantage of being gender neutral.
On an Letter Address Block or Envelope:
Technically anyone elected to office in the U.S. in a general election is entitled to be addressed as The Honorable. In practice however, while some members of local councils are addressed as The Honorable, many (perhaps most) are not.
For those who are not addressed as The Honorable, address as Dear Mr./Ms./Mrs./Dr./etc. (Name) and identify them by their office. The etc. means to use whatever honorific they normally use. For those who are addressed as The Honorable, see the forms below.
The only way to be certain of the tradition in your community is to call the office of your local council or board and check.

In a Salutation or Conversation:
Members of U.S. councils and boards are most formally addressed as Dear Mr./Ms./Mrs./Dr./etc. (Surname): or orally as Mr./Ms./Mrs./Dr./etc. (Surname).
Councilman/councilwoman are not formally used as honorifics in a salutation or in direct oral address. However, the staff of a member of a council may use the terms as honorifics for clarity, as when answering the phone “Councilman (surname)’s office” rather than “Mr./Ms. (surname)’s office” or when referring to the member in the third person as "the Councilman will be returning in ten minutes."
All that said, while Councilman/Councilwoman (surname) may not be the most traditional, it is sometimes the preferred honorific of a particular member, so follow the preference of the bearer.

Envelope, official: See note above regarding use of The Honorable.
The Honorable (full name)
(Title of position held), (Elected Body)
(Address)
for example
The Honorable Richard Trotter
Member, Montgomery County Board
(Address)
or
The Honorable (full name)
(Elected body) of (jurisdiction)
(Address)
for example
The Honorable Harriet Winslow
Board of Supervisors, Culpeper County
(Address)


Letter salutation:
Dear Mr./Ms. (surname):
or if the preference of the bearer
Dear Councilman/Councilwoman (surname):
