At the moment, in services which are not theoretically liberalised - as is the case with national postal services - there is a basic form of liberalisation, which is agreed within the framework of the Universal Postal Union, allowing for lower tariffs.
På nuværende tidspunkt er der inden for tjenester, der teoretisk ikke er frie - f.eks. de nationale postvæsener - en grundlæggende liberalisering, som foregår via Verdenspostunionens system og tillader lave takster.
