Due to increasing inflation, overprint stamps for the respective domestic postal rates were issued on January 14, 1946. The selling price was adjusted to the respective level of the currency. For the parcel rates and, in addition to 70 filler stamps, a 30 filler stamp (up to 5 kg with overprint "Cs. 5-I") and an 80 filler stamp (up to 10 kg with overprint "Cs.10-I") were used. The 30 filler and the 80 filler stamps from 1943 each showed the royal crown. In the nascent communist Hungary, the stamps were quickly withdrawn.
