## Official rule text

The Seller electronic address (BT-34) shall have a Scheme identifier.

## Why did my invoice fail BR-62?

The Seller electronic address (BT-34) — the seller's electronic delivery/routing identifier such as a Peppol endpoint — must carry a Scheme identifier that says which identifier scheme is used. Without the scheme (schemeID / EAS code) the value is ambiguous and cannot be routed reliably on the network.

## Common causes

- cac:AccountingSupplierParty/cac:Party/cbc:EndpointID has a value but no schemeID attribute.
- The schemeID uses an invalid or non-EAS code list value.
- The endpoint value was placed in a PartyIdentification/ID rather than in EndpointID with its scheme.

## How do I fix it?

```
<cbc:EndpointID schemeID="0088">7300010000001</cbc:EndpointID> (schemeID from the EAS / ICD code list, e.g. 0088 = GLN).
```
