Unfortunately, the 2l-5n transition date won't be much help in dating
the sign's installation.

Signs of the type you describe are often made in high volume and will
be used until the stock is exhausted even if the number if partially
obsolete. I've seen a great many such signs still in use where the
phone number was partially obsolete. For example, signs for a cab
company in a small town still had the old 5 digit number rather than
the current 7 digit number. So, the sign/fence could've been installed
well after the conversion.

Another possibility is that the fence was second-hand and in use before
used on your property.

Postal zip codes came out around 1964, but it took years for people to
change their addressing from the old zone system ("Philadephia 50, PA")
to zip code ("Philladelphia, PA 19150".

There is a highway company whose trucks to this day still say "DE 3" on
them. (I wanted to take a picture the other day when passing a work
area, but there was no place to safely pull over, plus taking pictures
these days of public works evokes suspicion and maybe a police
inquiry.)

One of the reasons we have mandatory ten digit and area code overlays
is to avoid splits for forcing people to get a new area code. That's a
nusiance for business people who must print up new stationery, change
their advertising, alert customers, etc. I'm lucky in that I still
have my original area code. My region had one split and I stayed on
the old side of the boundary. Even my cell phone is the old area code.
But now we have overlays. I'm glad I don't have a new area code, I
can't even keep track of them.
