About this plate
U. 2025 poz. 1326 is merely the latest in a chain running back through Dz. U. 2023 poz. 1778, Dz. U. 2019 poz. 560, Dz. U. 2017 poz. 447, Dz. U. 2011 nr 195 poz. 1160 and further, none of which was read here, so 2025 is the date of the instrument that STATES the rule and NOT the date the HP prefix began.
Region code notes
But note § 5 ust. 2 pkt 2 and § 6: a service may equally register a vehicle under an ORDINARY voivodeship+powiat number, and must do so for vehicles that are NOT liveried ("Tablic rejestracyjnych, które zawierają wyróżnik województwa i powiatu, nie stosuje się do oznakowanych pojazdów służb"). So an H plate implies a marked service vehicle, while an unmarked one wears a civil plate that no parse can distinguish.
How numbers are issued
§ 5 ust. 2 pkt 1: the service wyróżnik, then ONE letter from the 25-letter set, then the vehicle wyróżnik, which by ust. 4 is either a letter and three digits 001-999 or two digits 01-99 and two letters. Seven characters in total.
