Your Peppol ID is the address that makes you discoverable on the Peppol network. Just like a phone number, your Peppol ID allows other organisations to send invoices to you. Every organisation registered on Peppol has at least one Peppol ID.

A Peppol ID consists of two parts:

1. Identifier type (schemeID): determines which type of number is used
2. Organisation number: the number itself

Together they form the complete Peppol ID. For example: 0106:12345678 means Chamber of Commerce number 12345678.

The letter-code notation NL:KVK is a historical alias for scheme 0106 and is accepted by the PSB as equivalent. In external communications, eConnect uses the official numeric notation 0106 as the standard.

Not every country has its own EAS code in the Peppol code list. Canada and Curacao are examples of jurisdictions without a national Peppol scheme. Parties from these countries use an international scheme as the EndpointID:

• 0060 (D-U-N-S, Dun & Bradstreet)
• 0088 (GLN, GS1)
• 0199 (LEI, GLEIF)

The national tax number (such as a Canadian Business Number, GST/HST, or a Curacaoan CRIB number) is not a Peppol routing identifier in these cases. It is included for information in cac:PartyTaxScheme/cbc:CompanyID, with cac:TaxScheme/cbc:ID set to the value matching that tax type (such as GST, HST, TAX, or CRIB), not VAT. Peppol rule BR-CO-09 requires that a value under TaxScheme/ID = 'VAT' starts with an ISO 3166-1 country code.

See Identifiers in practice for the full XML example for such a supplier.

For Swedish organisations, the organisation number (scheme 0007) is the standard identifier. It is a 10-digit numeric number that passes the Luhn check (Peppol BIS rules SE-R-003, SE-R-004, and SE-R-013).

For sole traders (enskild firma), no separate organisation number exists. In that case, the 10-digit personnummer acts as the organisation number in Peppol. The Swedish VAT number is then 14 characters long: SE + 10-digit orgnr or personnummer + 01. For example, personnummer 8010070962 yields VAT number SE801007096201 (SE-R-001).

For invoicing the German government (B2G), the Leitweg-ID (schemeID 0204) is mandatory. Provide the Leitweg-ID exactly as registered by the recipient in the SML: in the canonical notation with hyphens, for example 0204:08-A1554-47. If the Leitweg-ID is supplied without hyphens (for example 08A155447), the SML lookup does not match the identifier and delivery fails with PartyId not found. This is not a separate hyphen syntax rule, but a consequence of SML matching: only the exact, registered identifier is found.

As soon as you activate an organisation on the eConnect platform, a Peppol registration is automatically created. For Dutch organisations, the Chamber of Commerce number (schemeID 0106) is the default identifier. This makes you immediately discoverable on the Peppol network, so other organisations can send invoices to you.

Receiving invoices via Peppol is turned off by default, as this is a paid service available from the Basic plan onwards. You can enable or disable receiving per identifier in your organisation settings.

You can register more than one identifier for the same organisation. This is useful in a few situations:

• Adding a VAT number: increases your reach because some senders search by VAT number rather than Chamber of Commerce number.
• Adding an OIN number: required if you invoice to or on behalf of the Dutch government.
• Foreign identifiers: if your organisation operates in multiple countries.

The more identifiers you have verified, the greater your reach on the Peppol network. For each identifier you can separately configure whether you want to send and/or receive on it.

Does your organisation invoice the Dutch government? Then an OIN number (schemeID 0190) is required. The OIN is always 20 digits long, structured according to scheme 0190 and left-padded with zeros (zero-padding) to 20 positions (e.g. 0190:00000001820029336000). You can find the OIN of government organisations in the OIN register.

When setting up your organisation for government invoicing, you need to set both the OrganisationID and the "Send via" field to OIN/OINO.

When sending Peppol invoices, recipient data is used in the following order for routing:

1. EndpointID (highest priority, required in Peppol BIS Billing 3.0)
2. CompanyID in PartyLegalEntity
3. CompanyID in PartyTaxScheme

Without an EndpointID, routing falls back to the Chamber of Commerce number if present. An email address in Contact/ElectronicMail serves as a fallback for delivery by email when the recipient is not registered on Peppol.

Want to check whether a recipient is registered on Peppol? You can verify this in several ways:

• In the platform: when composing an invoice, the platform automatically checks whether the recipient is registered.
• Peppol Directory: the public register of Peppol participants at directory.peppol.eu. May lag behind the actual SMP publication status.
• Peppol Lookup Service: since March 2026, lookup.peppol.org queries the SMP directly and shows the current publication status. Useful for troubleshooting.
• Via the API: the queryRecipientParty endpoint of the PSB checks the registration and indicates through which channel and format the recipient can be reached.

Discoverability is tied to the registration scheme. A recipient is only discoverable in the Peppol Directory and via lookup under the identifier scheme under which they are registered with their Access Point. Chamber of Commerce (EAS 0106) and VAT number (EAS 9944) are separate identifiers: an organisation registered only under 0106:<KvK> is not discoverable under 9944:<VAT> and vice versa. If a recipient cannot be found, check which scheme they are registered under first.

Lookup failed? Check this before concluding the recipient is not on Peppol:

1. Field placement. Peppol ID entered in the VAT field instead of the Peppol ID field: lookup fails. Move to the Peppol ID field, resend. Sender error -- no evidence the recipient is absent.
2. Different ID type. Field is correct but lookup fails: recipient is registered under a different ID. Check the Peppol Directory for: legalid, VAT number, companyid or IBAN.
3. Test customer XML. XML provided: Advisor tests the sending.

EAS codes with status "removed" have been permanently deleted from the official Peppol code list and can no longer be used for new registrations. Known examples:

Always verify that the EAS code you use is current in the official EAS code list when registering a Peppol identifier.

Want to register additional identifiers or activate receiving? You can do this in your organisation settings on platform.econnect.eu.
