Greece B2G: Invoice Number Patterns

The Greek Tax Authority, the Greek Independent Authority of Public Revenue (AADE), require that you the Document numbers you send match the following pattern:

{TIN}{Issue Date}{Serial Number}{Doc Subtype}{serial_number}{VRNL Invoice Number}

where:

• {TIN} is the Tax Identification Number (TIN) of either the supplier's or the tax representative's without the country's prefix.
• {Issue Date} the of issue in the DD/MM/YYYY format. This is explained in the IssueDate topic.
• {Serial Number} is the serial number of the installation from which the Document is issued. This is explained in the Greece B2G: Installation Serial Number topic.
• {Doc Subtype} is the document subtype code according to the Type of Standard Documents provided by AADE (the complete list of codes can be found in the section Invoice Subtype Code). This is explained in the Greece B2G: Invoice Sub Type Code topic.
• {serial_number} the series of the invoice if there is one. Use zero if none exists. This is explained in the Greece B2G: Invoice Series topic.
• {VRBL Invoice Number} is the invoice number that is specified in the VRBL Document in the Invoice/ID element. This is explained in the VRBL: Invoice Numbers topic.

In Vertex e-Invoicing, you send this information in various elements. The information is then assembled into the required format for submission to the Greek Tax Authority.
