"The Strip" in Las Vegas: What's the Actual Street Name?

Factual Questions
1

The title pretty much says it all.

If I were going to send mail to the Cecil Adams Hotel & Casino, it wouldn’t look like this:

Cecil Adams Hotel & Casino

The Strip

Las Vegas, NV #####

So what word belongs in the street field?

2

Las Vegas Boulevard.

Technically, most of the strip is not in Las Vegas. Everything south of Sahara Ave is beyond the city limits.

Though I think the mailing address would still be Las Vegas, NV, if that’s what your asking. It’s just unincorpoated Las Vegas.
