Explained
Where it is used
- Electronic invoices (e-qaimə) for B2B transactions.
- Contracts, acts and other business documents.
- Bank accounts, payment provider onboarding and merchant agreements. See accepting online payments.
- Registration on marketplaces and platforms as a seller.
- Government portals and reporting.
In websites and software
- B2B checkouts and portals should collect the buyer's VÖEN and legal name when invoices are needed, so accounting does not have to chase them later. See B2B e-commerce portals.
- Validation: check the format (digits only, expected length) at entry; where official lookup services are available and permitted, they can confirm that the number belongs to the stated company.
- CRM records: store VÖEN with company records to link sales, invoices and payments consistently.
Seller information
Online stores and service websites typically publish the seller's legal name and tax number in their terms or contact information, which helps customers and payment providers verify the business. See e-commerce law basics.
