### Manual entry of Peppol ID

If your customer does not work according to identification based on a Belgian company number,
you can manually perform a Peppol check using a number of other identifications:
* 0208: Belgian company number
* 9925: Belgian VAT number
* 0088: GLN number
* 0106: Dutch Chamber of Commerce number
* 9944: Dutch VAT number
* 9930: German VAT number
* 9957: French VAT number

Once you have filled in all the details, click on “check Peppol.”

After checking, you will immediately see whether your customer is registered on the Peppol network and can receive Peppol invoices. 


| You can only send invoices via Peppol if your customer is actually able to receive them. If your customer is not yet Peppol ready, you will not see this sending option.
