[[Autostrade of Italy]] follow a single numbering, even if managed by different concessionaire companies: they are all marked with the letter "A" ("RA" in the case of motorway junctions, with the exception of the [[Bereguardo]]-[[Pavia]] junction numbered on the signs as [[Autostrada A53 (Italy)|Autostrada A53]], and "T" for the international [[Alps|Alpine]] tunnels) followed by a number. Therefore a motorway with the same numbering can be managed by different concessionaire companies (for example the [[Autostrada A23 (Italy)|Autostrada A23]] is managed for a stretch by {{ill|Società Autostrade Alto Adriatico|it}} and for the remaining stretch by Autostrade per l'Italia<ref>{{Cite web|url=http://www.programmazioneeconomica.gov.it/wp-content/uploads/2019/07/esito-CIPE-24-luglio-2019-SI-PUBBLICHI.pdf|title=CIPE - Esito seduta del 24 luglio 2019|access-date=27 September 2019|language=it}}</ref><ref>{{Cite web|url=http://www.autostradealtoadriatico.it/Home/Company|title=La Società - Società Autostradale Alto Adriatico|access-date=21 September 2019|language=it}}</ref>). In road signs the alphanumeric acronym is enclosed (not in the case of the 16 junctions) in a green octagon with a white acronym. The numbers of motorways and tunnels are assigned with a circular from the [[Minister of Infrastructure and Transport (Italy)|Minister of Infrastructure and Transport]] to be published in the ''[[Gazzetta Ufficiale]]''.<ref>Art. 129 of the ''Regulations for the Implementation of the Italian traffic code'' in relation to article 39 of the Italian traffic code.</ref>
