What is it?

A GS1 Digital Link is a URL that encodes GS1 identifiers (such as GTINs, GLNs, or SSCCs) in web-resolvable format, following the GS1 Digital Link standard (ISO/IEC 18975). Instead of a standalone numeric code, a GS1 Digital Link is a structured URI that resolves to product, location, or organization information through GS1-compliant web infrastructure. Schema.org's hasGS1DigitalLink property attaches this URL to an Organization, Place, Product, or Offer, linking the entity to GS1's global registry infrastructure via a standard web address.

Why this matters for AEO

GS1 Digital Links represent the bridge between traditional barcode and supply chain identifiers and the web. When an organization publishes a hasGS1DigitalLink URL in its structured data, AI systems can resolve that link to retrieve authoritative data from GS1's infrastructure: product specifications, location records, or organization information. This is particularly relevant for organizations in retail, healthcare, food, and logistics where GS1 identifiers are embedded in packaging and supply chain systems. For AI answer engines answering questions about product origin, distribution, or traceability, a GS1 Digital Link is a machine-traversable path to verified data.

What the specs say

Schema.org:hasGS1DigitalLink expects a URL value. The GS1 digital link associated with the object. [Source: https://schema.org/hasGS1DigitalLink]

Google: Not mentioned. This field does not appear in Google's structured data documentation for Organization. It has no current rich result treatment. It contributes to supply chain data linkage rather than traditional search features. [Source: https://developers.google.com/search/docs/appearance/structured-data/organization]

How to find your value

A GS1 Digital Link URL is constructed from your GS1 identifiers according to the GS1 Digital Link standard. Steps:

1. Confirm you have a GS1 Company Prefix from your national GS1 member organization.
2. For an organization, the relevant identifier is typically a GLN (Global Location Number).
3. A GS1 Digital Link for a GLN takes the form: https://id.gs1.org/417/{gln} where {gln} is your 13-digit GLN.
4. Alternatively, use your GS1 resolver URL if your organization operates its own GS1 Digital Link resolver.
5. Consult the GS1 Digital Link standard documentation at https://www.gs1.org/standards/gs1-digital-link for full URI construction rules.

If your organization does not yet have a GLN or GS1 Company Prefix, contact your national GS1 member organization before implementing this field.

Format and code

hasGS1DigitalLink accepts a URL value. For an organization identified by a GLN, the standard GS1 canonical URI base is https://id.gs1.org/:

{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "Unilever NV",
  "hasGS1DigitalLink": "https://id.gs1.org/417/5000112642655"
}

In this example, 417 is the GS1 Application Identifier for GLN of a party, and 5000112642655 is Unilever's GLN. For a product on the same page (valid since the property also applies to Product):

{
  "@context": "https://schema.org",
  "@type": "Product",
  "name": "Dove Beauty Bar",
  "hasGS1DigitalLink": "https://id.gs1.org/01/09780201379624"
}

Here, 01 is the Application Identifier for GTIN-14, followed by the product barcode. Invalid formats:

{
  "hasGS1DigitalLink": "5000112642655"
}

The value must be a full URL, not a bare GLN string.

Static pages

Add to your homepage or About page via Page Settings > Custom Code > Head Code:

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "Your Company",
  "hasGS1DigitalLink": "https://id.gs1.org/417/1234567890123"
}
</script>

CMS template pages

For sites with product catalogs where each item has a GS1 Digital Link, this property can be bound to a CMS field. Add a URL field to your Products CMS collection, store the full GS1 Digital Link URL for each item, and bind it to the hasGS1DigitalLink property in the product schema template.

In Schema HQ

The hasGS1DigitalLink field is set in the Organization schema editor. The field accepts a full URL. For product-level schemas, Schema HQ's CMS field mapping allows binding this property to a CMS URL field on a per-item basis.

Real examples

GS1's canonical resolver at https://id.gs1.org/ is the reference infrastructure. Unilever, Nestle, and other large CPG manufacturers participate in GS1 Digital Link programs. A representative organization-level usage:

{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "Nestle SA",
  "url": "https://www.nestle.com",
  "globalLocationNumber": "7611400000004",
  "hasGS1DigitalLink": "https://id.gs1.org/417/7611400000004"
}

FAQ

Is hasGS1DigitalLink only for product barcodes?

No. While GS1 identifiers are best known for product barcodes (GTINs), the Digital Link standard covers all GS1 identifier types including GLNs (for locations and organizations), SSCCs (for logistics units), and GRAIs (for returnable assets). When applied to an Organization, the relevant identifier is typically the GLN.

Does this replace the globalLocationNumber field?

No. globalLocationNumber stores the raw 13-digit GLN as a plain text string. hasGS1DigitalLink stores a full URL that encodes that same GLN (or another GS1 identifier) in a web-resolvable format. They are complementary. Including both in the same schema block is valid and provides maximum interoperability.

Who maintains the id.gs1.org resolver?

GS1 Global Office maintains https://id.gs1.org/ as the canonical GS1 Digital Link resolver. Queries to this resolver redirect to data sources registered by GS1 member organizations for each identifier. Individual companies can also operate their own branded resolvers that comply with the GS1 Digital Link standard.
