# Peppol electronic invoice module for Dolibarr
Peppol is (among other things) an electronic invoice format used in almost all of Europe (except Germany-France which use [[en:projet_factur-x:accueil|Factur-X]]). The Peppol module for Dolibarr lets you generate invoices in this format and send them to your correspondents.
## Customer's electronic identifier
The default electronic customer identifier is the customer's intra-Community VAT number. However, some customers may have a "peppol identifier" which should be used as a priority.
Since version 1.0.28 of 18/07/2023, you now have a new field in the Third Party file that allows you to store this information, which will then be used when the XML file is generated.

Since version 1.0.50 you can also click on the link to the right of the peppol ID to check in the directory whether this number is correct.
