Yes. It's clever decision. See the citation from page http://www.usno.navy.mil/USNO/astrometry/optical-IR-prod/ucac
"UCAC3 official star numbers While the MPOS number (last column on each data record) mainly provides a means to identify known high proper motion stars, the primary star identification number should look like: 3UCzzz-nnnnnn The "3UC" is constant and indicates the UCAC3 catalog. The 3 digit "zzz" number is the zone the star is in, followed by a dash and a 6 digit number which is the record number of the star on that zone. Thus the official designation of the star 42 in zone 7 would be 3UC007-000042.
