Introduction to the PEPPOL Directory
The PEPPOL Directory is a publicly accessible database that lists all businesses registered to send and receive electronic invoices through the PEPPOL network. For Polish businesses, understanding the PEPPOL Directory Poland is essential for verifying trading partner capabilities and ensuring smooth invoice exchange.
This guide explains what the PEPPOL Directory is, how it works, and how Polish businesses can use it to identify PEPPOL-enabled trading partners.
What Is the PEPPOL Directory?
The PEPPOL Directory is a central lookup service maintained by OpenPeppol. It stores the PEPPOL Participant Identifiers (IDs) of all registered businesses, along with information about the document types they can receive. The directory enables senders to verify that a recipient is registered on the PEPPOL network before sending an invoice.
Each entry in the PEPPOL Directory Poland contains the participant’s PEPPOL ID, country code, business name, and the list of document profiles they support. This allows senders to confirm not only that a business is on PEPPOL, but also whether they can receive specific invoice formats such as PEPPOL BIS Billing 3.0.
How the PEPPOL Directory Works
When a business registers with a certified PEPPOL access point, the access point publishes the business’s participant information to the PEPPOL Service Metadata Publisher (SMP). The SMP in turn makes this information available through the PEPPOL Directory.
The directory uses a DNS-based lookup mechanism that allows access points to automatically route invoices to the correct recipient. When a sender initiates an invoice, their access point queries the directory to find the recipient’s SMP and retrieve their endpoint URL for secure document delivery.
For businesses using WooCommerce E-Invoicing or Epicor Kinetic E-Invoicing, integration with a PEPPOL access point provides automatic directory lookup during the invoice sending process.
PEPPOL Directory and Business Identification
Business identification in the PEPPOL network is based on standardised identifier schemes. For Polish businesses, the most common identifier is the NIP (Tax Identification Number), combined with the Polish scheme code in the PEPPOL participant ID format.
Polish public sector entities are typically identified using their GLN (Global Location Number) or VAT number. The combination of the scheme code and identifier must remain unique within the PEPPOL network to ensure accurate invoice routing. Epicor Kinetic E-Invoicing supports reliable recipient identification and compliant invoice delivery across the network.
Businesses should confirm their PEPPOL participant ID with their access point provider to ensure it is correctly registered in the directory before attempting to send or receive invoices.
Finding Businesses in the PEPPOL Network
The PEPPOL Directory can be searched using a business’s name, VAT number, or PEPPOL participant ID. The search interface is available at directory.peppol.eu and provides a straightforward way to check whether a specific business is registered on the network.
Search results display the business’s registered name, country, PEPPOL ID, and the document types they are configured to receive. If a business does not appear in the directory, they are not currently registered on PEPPOL and cannot receive invoices through the network. The Best E-Invoicing Solution helps businesses verify recipient registration before sending invoices.

Benefits of the PEPPOL Directory for Businesses
The PEPPOL Directory provides several practical benefits for businesses. It enables automated routing of electronic invoices without requiring prior agreement between trading partners on technical delivery details. This simplifies the process of adding new PEPPOL-enabled suppliers and customers.
The directory also supports interoperability across different access point providers, since all PEPPOL participants share a common directory regardless of which access point they use. This open architecture is a core strength of the PEPPOL model.
For Polish businesses expanding into new EU markets, the PEPPOL Directory provides visibility into which potential partners are already PEPPOL-enabled, making it easier to identify opportunities for automated invoice exchange.
Conclusion
The PEPPOL Directory is a fundamental component of the PEPPOL network, enabling businesses to locate and connect with PEPPOL-enabled trading partners anywhere in Europe. Polish businesses should ensure they are correctly registered in the directory to facilitate seamless invoice exchange with domestic and international partners.
Understanding how the directory works and how to search it effectively is an important capability for any business implementing PEPPOL e-invoicing in Poland.
