Sending electronic invoices for public contracts has become mandatory for large companies and will soon be for small and medium-sized enterprises.

In order to transmit your electronic invoices to the right recipient, it is essential to understand what the Peppol identification number is and what this number is for.

What is a Peppol identification number in Luxembourg?

A Peppol identification number is a unique identifier that allows you to transmit an e-invoice to the right recipient via the Peppol network.

In Luxembourg, this number starts with 9938 and is followed by ":" and the recipient's VAT number.

For example: 9938:lu1359935

Please note that when a public body has several departments or divisions, this number can be a unique number also starting with 9938 but not containing a VAT number but a unique identifier number.

For example: 9938:20225000078
