Greece
Greek B2B e-invoicing is a tax-platform mandate - invoices are issued via licensed providers and reported in real time to myDATA - while B2G invoices route over Peppol to one single central endpoint for the entire public sector.

Frequently asked questions
01Is e-invoicing mandatory in Greece?
Yes, in phases. Businesses with 2023 gross revenue above €1 million must issue electronic invoices since 2 March 2026; all other in-scope businesses follow from 1 October 2026, with a conditional adaptation window to 31 December 2026. B2G invoicing above €2,500 has been fully in force since September 2025.
02Can I comply through a regular Peppol Access Point?
Not for domestic B2B. Greek businesses must issue invoices through an AADE-licensed e-invoicing provider (YPAHES) or AADE's free timologio/myDATAapp tools - an ERP or plain Access Point alone is not an accepted route. B2G and cross-border invoices, by contrast, do run over the Peppol network.
03What is myDATA and the MARK?
myDATA is the Greek tax authority's digital reporting platform. Every invoice issued through the accepted channels is transmitted to AADE in real time and receives a unique registration number (MARK). The data feeds pre-filled VAT returns (since 2024) and income-tax returns (since 2025).
04How do I invoice a Greek public body?
Send an EN 16931 / Greek CIUS invoice over Peppol to the single central public-sector endpoint 9933:997001671 at the National Interoperability Centre (KE.D). The actual recipient is resolved from mandatory fields such as the contracting-authority identifier and contract references - not from the authority's own VAT number.
