Dun & Bradstreet
Dun & Bradstreet (D-U-N-S® Numbering): Viesgo uses the DUNS® numbering system for unequivocal identification of all suppliers. DUNS®, which stands for Data Universal Numbering System, was developed by Dun & Bradstreet (D&B) in 1962 and is today considered the international standard in supplier identification, assigning a single nine-digit number to each. Each code is only used once. The DUNS® identifier is considered the single, international benchmark for identifying a company and is recognised and recommended by the United Nations, European Commission, German Automotive Association (VDA) and International Organization for Standardization (ISO). Every company is assigned a DUNS® identifier by D&B at no registration cost whatsoever.
