Yes and even companies that can request it (I worked for one in this role) have to provide extensive documentation. A phone must be purchased for us (with invoice with serial no) originally, or it must have been enrolled in our corporate MDM before getting locked. And for a while they didn't even accept the latter. So even if you are at a third party you won't get away with sneaking these through. Which is good, a bit annoying sometimes though when some of our vendors didn't provide serial number invoices. We now require it but during the first years of anti-theft lock it was a bit of an issue and caused a lot of e-waste for us, sadly.
