Other Invoicing arrangements: Self-billing: Requests to validate the VAT registration status of suppliers

The obligation for establishing the registered status of suppliers lies with the customer.

If a customer requests confirmation of the validity of a supplier’s VAT registration number, the general principles in IDG - Information Disclosure Guide must be followed. Neither the request nor the reply need be in writing, but a record of the disclosure must be made in the enquirer’s eFolder.

Requests for the validation of the list of suppliers must be acted upon. A manual validation using VISION is to be undertaken locally, within resource constraints.
