is UID of mifare classic editable?

It would be nice if UID is write-protected so that I can use it to detect card clones. So, can it be modified?

As far as I know, the UID-s of the Mifare Classic are'nt guaranteed to be unique, so beware of that problem.

Yes and no. The standard Mifare Classic has a locked sector 0, where the UID is stored. However, if you Google changeable uid mifare, you'll find several (comparatively expensive) cards for sale with sector 0 unlocked.
