Considerable discrepancies occur among catalogs as to how many basic Hungarian stamp releases were overprinted by the NZRU. Some compilations list all of the dozens of revenue stamps that were prepared. Others ignore most of these stating that they were essays and therefore never put into postal circulation. No two listings are the same and this has caused a great deal of confusion among philatelists.

Nevertheless, there are basic characteristics of these overprints that everyone does agree upon. The Uzhhorod overprints all consist of three lines of Ukrainian text: "Poshta Zakarpatska Ukraina" (Post of Transcarpathian Ukraine) plus a denomination. (Although not indicated, the value is in Pengő and/or fillér.) Three distinct overprints (A, B, and C - see Figure 8) were employed. Overprinting of Hungarian stamps took place at two different times in two different printeries. That is about all that can be stated with certainty, as the various experts are in disagreement about the specifics.
