License number has the same format for all products and consists from the three paths. The first is the product identifier: PLSK for Plesk, SB for Sitebuilder, VZ for Virtuozzo, HSPC for PBAS (formerly HSPcomplete) and EXP for Expand. The second eight digits path is unique one and actually it is the license number. And the four digits third path is the number that indicates how many times the license was updated, upgraded and renewed.

It is always important to know the full license number if you contact Parallels support. How to find the license number for Parallels server products is described in the articles below:
