I have two SE's both purchased the same week in Sept 2017 from Best Buy for $140 as AT&T Prepaid phones. One was located by serial number, the other is not finding the serial number. If I do the search based on AppleID / name, it locates the same one that the serial number lookup located.
Other family members have iPhone 6s Plus's and they were located by serial number.
