ADM updates online-gambling system protocols for use from 24 September
Italy’s Customs and Monopolies Agency (ADM) published version 1.2.1 of its procedures for checking communications between concessionaires and the central system, effective 24 September 2026. The update changes technical and accounting-message specifications; ADM said successful checks completed under version 1.2 remain valid and need not be repeated.
Concessionaires can use the revised protocol without repeating successful checks completed under the previous version.
