The prefix UJ was used for Tajikistan prior to the break-up of the USSR.

As was usual with USSR callsigns, the first letter of the suffix denoted the oblast.

Prefix Oblast # Oblast name
UJ#J 040 Districts of Republican Subordination
UJ#K  182 Kulab (before 1988-09-08 and after 1990-01-24)
UJ#K 192  Khatlon (from 1988-09-08 to 1990-01-23)
UJ#R 042 Gornyj Badakhshan GBAO
UJ#S 041


UJ#X 183 Kurgan-Tube (part of oblast #192 from 1988-09-08 to 1990-01-23)

Following independence, from 1994-01-01 the prefix for Tajikistan became EY and administrative regions were denoted by the call area, not the first letter of the suffix.
