How can I determine whether an individual is a licensed electrician in
New York State - or is it city - or is it borough or what? I have a
first name and a last name. Please do not tell me to look at some copy
of a
possibly "forged" certificate! I want to know whether this person is
REGISTERED with the appropriate agencies!
Thank You.

The licensing of electricians in NYC is handled by the New York City
Bureau of Electrical Control, which is part of the Licensing Division
of the New York City Department of Buildings:

New York City Department of Buildings: Frequently Asked Questions

Here you'll find more information on the "Building Information System"
that is mentioned in the FAQ quoted above:

The BIS was not functioning when I tried it, but it's possible that
the site is undergoing weekend maintenance. If you want to investigate
the BIS, I suggest trying it tomorrow, during working hours. Your best
bet probably is to take the advice of the FAQ: telephone the Bureau of
Electrical Control at 212 669-8672 and give them the full name of the
person whose licensure you'd like to check.

Below I've linked to a cached page (possibly a slow-loading one) that
will give you an idea of what to expect from the BIS. Note that
there's a link for "Skilled Trades Licensees Search." Once the BIS is
up and operating again, that link (on the real BIS site, not the
cached copy, of course) should help you to obtain exactly the
information you need.

This is the combination of search terms that gave me the best results
in locating this information for you:

Google Web Search: "new york city" + "how do I" + 'licensed
electrician"

I hope this will enable you to make a determination on the licensing
status of your electrician. If anything is unclear, please request
clarification; I'll be glad to offer further assistance before you
rate my answer.

EXCELLENT and THANK YOU!
