At the end of November 2023 Google announced extended structured data support for Organizations. This included the option to provide ISO 6523 identifiers for your organization via the iso6523Code schema.org property. These identifiers consist of an ICD (International Code Designator) that indicates the type of identifier and the identifier itself. e.g. Our Australian Business Number (ABN) identifiers have an ICD of 0151, making my business iso6523Code “0151:55609885501”. This property can accept an array of values, letting you identify your business in multiple ways. Many countries have an ICD for their business tax identifier (e.g. VAT number), and there are some more global ones available, e.g.:

  • 0060: Dun & Bradstreet Data Universal Numbering System (DUNS)
  • 0088: GS1 Global Location Number (GLN)
  • 0199: Legal Entity Identifier (LEI)

Here’s a simple example of an Organization listing some business identifiers. This was provided by Matthias Wiesmann, who knows a thing or two about this stuff (as in a lot):

{
  "@context" : "https://schema.org",
  "@type" : "Organization",
  "name": "Klick-Tipp Limited",
  "url" : "https://www.klicktipp.com/",
  "iso6523Code": ["0199:9845000B1ED2C9F55818", "0060:2216853822", "9932:113364153"], 
  "address" : {
    "@type" : "PostalAddress",
    "addressCountry": "UK",
    "addressLocality": "London",
    "streetAddress": ["15 Cambridge Court", "210 Shepherd’s Bush Road"],
    "postalCode": "W6 7NJ"
  }
 }
