I was under the impression that having the MAC address on the device's label was some kind of regulatory requirement for Wifi - I have never seen a wireless device without it.

I think that's for APs, given pretty much no smartphone has its MAC printed on it.

Oh, true! I thought it was the MAC address in tiny print on iPhones but it's actually the FCC ID and IMEI. On the other hand, all smartphones have the MAC and serial number easily accessible in their settings menu.

You must not have seen an iPhone in quite a while. There is absolutely nothing printed on iPhones these days, all of the regulatory stuff is under the Settings menu.

Depends on the country. Although they have been hiding it pretty well, and usually it is only symbols and not detailed information like IDs.

Many phones let you rotate your MAC too, to prevent profiling...

iPhones haven't been doing that for years - they have no markings other than the apple logo on the back.

[trangus_1985]

It is a requirement, although you can now use "e-labels". Such as, a page in the settings that has the FCC information. (IANAL)

Where does your phone have this sticker?

[drfuchs]

In the battery compartment.

No, or at lease, not on iPhone: https://guide-images.cdn.ifixit.com/igi/QAtX1WnxfYrMhOZg.hug... (13 on the left, 12 on the right; via iFixit)
