On wifi 2.4GHZ transceivers they require to be FCC certified:


"Certified" basically means that the device meets or exceeds all of the
requirements set forth by the FCC.


Are vendors required to supply FCC numbers by law to inquiring
customers?

Possibly, depending upon the type of device. What "number" specifically?


Are radios that have been modified such as placed in an enclosure with
antenna required to be recertified by law?

Not if you did it yourself and have no intention of marketing it.

"Certification" or "Type acceptance" is basically used for mass marketing
letting the public know that the device does meet the minimal requirements.


What is the real-world policy of the FCC on the above two questions?

Thanks, in advance, for any helpful answers
