Yes, quite a few. The first #1 ESS deployment was, as I recall, in
1967. It started off slow, but DC became the first place to experience
a major deployment, for obvious reasons. ;-)
The public wouldn't have known about it because calling features weren't
promoted much, and not at all in some areas, until 1975, or so.
Touchtone was available on No 5 XBAR in most of those areas in the the
The AT&T network policy makers deliberately held back on offering
calling features in the POTS environment for a number of reasons. But,
Centrex government customers in DC were offered the full array as soon
as the cuts were complete.

Here is a ad featuring a Correcting Selectric II in 1973.
I know, as I bought one then. ;-) The first Selectric came out in 1961.

I'd have to look through my old BSTJ's but I recall the AMPS tests
being conducted in New Jersey in the late 1970s. Chicago was the
first launch of AMPS in 1983.
[TELECOM Digest Editor's Note: Do you recall one difference between
the way 'call forwarding' was originally set up and later on? People
could 'chain call-forward', that is, you forward yours to me; I then
forwarded mine to some other party; they forwarded theirs onward, etc.
Let's call them parties 'A', 'B', 'C' and 'D'. People realized they
could forward infinitly if they had enough co-conspirators to help
them, and make a (considerable) long distance call for the price of
a local call. The next generic of 'call forwarding' did not allow
that. Yes, A could forward to B and B could forward to C, etc, but
calls directed to A _stopped_ when they reached B. Calls directed to
B _stopped_ when they reached C. Officially the theory was that
persons calling A only wanted to talk to A. For A's convenience, his
calls could be forwarded to B, but party A did not want to be
forwarded onward to C or D. Or, so said telco. And originally, if A
forwarded to B and contemporaneously B forwarded to A, it would start
an endless loop until eventually all circuits in the CO were tied up.
Telco quickly put a stop to that also. But that 'chain forwarding' was
foolish anyway; people could rarely -- if ever -- make a series of
short distance calls for less expense than a single long distance
