France E-Invoicing: The ESSENTIALS of the reform #1 Addressing and Directory

Version 2.4 of the PPF external specifications focus on the operation of the PPF in its interaction with public or private entities.
The specifications describe the interactions with Dematerialization Operators (DO) and Partner Dematerialization Platforms (PDPs) for invoice exchanges and lifecycle statuses.
The PPF Directory contains all the reachable email addresses of VAT payers and public entities.
The email addresses for receiving invoices are based on the company’s SIREN number.
Companies can define multiple invoice receipt email addresses based on their needs, but it is recommended to have a limited number of addresses.
The SIREN_SUFFIXE format is suitable for private companies, while the SIREN_SIRET and SIREN_SIRET_CODE_ROUTAGE formats are more suitable for public entities.
The PDPs/PPFs update the PPF Directory with the email addresses and other information.
The directory is public and accessible to all companies through their PDP/PPF.
The directory allows companies to find up-to-date invoice receiving addresses of their recipients and facilitates the transmission of invoices.
The directory also supports interoperability between PDPs/PPFs and ensures the portability of electronic addresses.
