# PEPPOL participant identifiers

> Understand PEPPOL participant identifier formats, schemes, and how to assign them to organizations for e-invoicing.

## Overview

To exchange electronic documents through the PEPPOL network, both senders and receivers need a globally unique address called a **PEPPOL participant identifier**, or PEPPOL ID.

PEPPOL IDs consist of two fields separated by a colon:

* the [*scheme*](#schemes), which defines the identifier type,
* the *identifier*, which is usually the company's VAT number or business registration number.

Example:

```lines theme={null}
0106:12345678
```

This PEPPOL ID refers to a Dutch company with KVK 12345678.

The full participant ID used in the raw PEPPOL XML format also includes an additional *superscheme* prefix:

```lines theme={null}
iso6523-actorid-upis::0106:12345678
```

## Supported PEPPOL schemes

Tesouro supports the following [PEPPOL participant ID schemes](https://docs.peppol.eu/edelivery/codelists/old/v9.2/Peppol%20Code%20Lists%20-%20Participant%20identifier%20schemes%20v9.2.html).

<Note>Tesouro API uses the scheme names (such as NL:KVK) rather than their ICD codes (0106).</Note>

## Register a PEPPOL ID

Tesouro automatically registers [organizations](/finops/guides/organizations/index) in PEPPOL during [e-invoicing onboarding](/finops/guides/e-invoicing/onboarding).

[Counterparts](/finops/guides/common/counterparts/index) are assumed to be already registered through their PEPPOL access point of choice.
