Introduction
While the other families in this section concern what symbols may assert, a parallel change is rebuilding the layer beneath them: the machine-readable identity of the package. The linear barcode, in use since 1974, is being succeeded by two-dimensional codes carrying GS1 Digital Link. That syntax can point to a web address. Whether law lets required information live there is a different question.
The standard: identifiers expressed as web addresses
GS1 Digital Link is a URI syntax, that is, a standardised means of expressing GS1 identifiers — the GTIN in particular — as web addresses. Its current version, release 1.7.0, ratified in August 2026, specifies the structure: an HTTPS address whose path carries the primary key, being the GTIN, followed by optional qualifiers such as batch and lot or serial number, and whose query string may carry attributes such as expiry dates (GS1, 2026). Encoded in a QR code — the "QR Code powered by GS1" — a single symbol serves two readers that previously required separate carriers: a point-of-sale scanner extracts the GTIN and completes the sale, whereas a consumer's phone camera resolves the address and opens whatever the brand has published at it.
The architecture's operative component is not the syntax but the resolver. The companion GS1-Conformant Resolver standard defines how a single Digital Link address returns multiple destinations by link type, so that one code resolves, according to requester and context, to consumer information, regulatory disclosures, recycler data or a product passport (GS1, 2026). The resolver thereby converts the package's identifier from a pointer into a routing service, and it is that routing capacity which renders the digital-labeling arrangements examined across this theme's final group technically coherent: one printed carrier, multiple audiences, each served a distinct response.
The Sunrise 2027 milestone and its scope
Sunrise 2027, described by GS1 as "Ambition 2027", is a capability goal for retail infrastructure. In the standard's own framing, it concerns "the transition from legacy linear 1D barcodes to new, more capable 2D barcodes on pack with an initial goal of Retail POS scanners globally capable of reading and processing both old and new barcodes by the end of 2027" (GS1, n.d.). GS1 US states the corollary directly: Sunrise 2027 "is not necessary to implement all the capabilities of 2D by that date" (GS1 US, n.d.).
The commitment, unpacked, is that retailers' point-of-sale systems should by the end of 2027 be able to read 2D codes alongside linear ones. It does not commit brands to print 2D codes by 2027. It does not retire the linear barcode, which continues alongside 2D codes through an open-ended dual-marking period. It does not mandate anything, GS1 being a standards body and the ambition being an instrument of adoption coordination rather than of regulation. Moreover, it does not require the consumer-facing capabilities — resolvers and published content — that give Digital Link its labeling significance. A brand printing only linear barcodes on 1 January 2028 would not thereby contravene any requirement. The date's function is one of coordination economics: scanning infrastructure is the transition's reciprocal-dependency constraint, and a shared capability deadline allows brands to invest in 2D artwork on the expectation that checkout lanes will read it.
The installed base in deposit return schemes indicates the likely pace of the transition. Across Europe's deposit return schemes, which are among the most machine-intensive packaging infrastructures in operation, linear barcodes remain the identifier of record, and the GTIN is the operative key in every surveyed system (GS1 in Europe, 2024). Infrastructure that disburses cash per scan migrates last, from which it follows that the dual-marking period will be extended.
Syntax structure and institutional lineage
The syntax merits description in detail, because the design's labeling implications reside in its parts. A Digital Link address is an ordinary HTTPS URI whose path encodes the GS1 keys hierarchically: the GTIN as primary key, followed optionally by qualifiers narrowing identity, namely batch and lot and then serial number, with further attributes such as expiry carried in the query string (GS1, 2026). The hierarchy carries the labeling payload, in that a resolver may answer at any level of it. The same standard consequently spans class-level communication, such as a product line's disposal guidance, and item-level communication, such as an individual package's rotation count, the granularity that the EU's reuse architecture requires, without any change of carrier. The depth at which identity is resolved becomes a publishing decision rather than a printing one.
The institution's lineage bears on the transition's tempo. The organisation now setting this syntax standardised the retail barcode in 1973, scanned its first product in 1974, and consolidated its transatlantic governance into the present structure in 2005; its identifiers now run through millions of member companies globally (GS1, n.d.b). Two properties of that history bear on the 2D transition. The first is the gravity of the installed base: the linear barcode's universality was built over decades of coordinated retrofit, and its successor inherits both the coordination machinery — the national member organisations and the sunrise-date convention itself, Sunrise 2027 following earlier sunrise milestones in the system's history — and the associated timescale, in which transitions of this kind proceed by gradual accumulation rather than by deadline. The second is the strategic significance of neutrality: the system's not-for-profit, industry-governed form is the reason competing retailers and brands entrust their identification layer to it, and is also the reason that, as regulation reaches for data carriers, a private standard recurs within public architecture, since the neutrality that makes it acceptable to commerce also makes it available to regulators who could not mandate a proprietary equivalent.
Relevance of the identification layer to labeling
The identification layer's relevance is not that a QR code constitutes a label, but that machine-resolvable identity alters what labels are required to do. Three mechanisms are already observable within this theme.
Localisation. The structural difficulty of printed recyclability communication, documented throughout this collection, is that the truthful message varies by jurisdiction whereas the package does not. A resolved identifier can vary: the same code answers a Berlin scan and an Ohio scan differently, routing each reader to disposal guidance for the relevant system. Digital Link is the technical form of the approach — harmonised syntax with localised semantics — identified in the global-standard article as the realistic endpoint for the locality problem.
Regulatory carriage. The EU's packaging regulation has already legislated the pattern, providing for mandatory data carriers for reuse-system information and rotation tracking, digital-only carriage of the EPR symbol from 2027, and QR-based supplementation of the harmonised sorting labels (Complydex, n.d.). Each obligation presumes what Digital Link standardises, namely a package-level identifier resolving to structured and updatable information; and the EU's product-passport architecture, examined next, generalises the presumption across product law. The standard is thereby becoming the de facto carriage layer for European packaging disclosure without appearing by name in any regulation.
Relocation of claims material. As claims law tightens around printed assertions, through per se prohibitions and qualification duties, the resolved layer offers what print cannot, namely space for the qualifications, substantiation and market-specific caveats that lawful claims increasingly require. Whether law permits required information to be delivered behind a scan is the contested question treated in this group's final article; what the identification layer settles is that the information can be held there at all, in versioned and auditable form.
Governance of the resolver
The architecture's capability concentrates at the resolver, and so do the governance questions it leaves unsettled.
A resolver determines what a scanned identity returns: which link types exist, what each audience receives and, since resolution is a live service, what changes and when, without any alteration to the printed package. Each element of that capability carries a corresponding governance question. Updatability means the package's asserted meaning may change after sale, so that the disposal guidance a consumer scanned at purchase may differ at disposal, and no doctrine yet addresses which version binds for claims purposes. Localisation means the same package lawfully conveys different content in different places, which realises the field's structural aspiration while admitting the possibility of jurisdictional arbitrage in what each market is shown. Audience differentiation means the regulator's view and the consumer's view of the same identity may diverge by design, which is efficient in operation and in tension with the premise that any party may check what a package claims.
The standard's response to date is procedural: conformant-resolver requirements discipline the mechanics (GS1, 2026), and the brand controls its own resolution, on the same allocation as applies to any corporate website. Whether that allocation survives the layer's regulatory conscription remains open. Where EU law makes the carrier the only channel for EPR identification and a mandatory channel for reuse-system data, the resolved content ceases to be marketing and becomes compliance disclosure; and compliance disclosure ordinarily carries record-keeping, versioning and audit obligations that consumer-web infrastructure was not designed to bear. One settlement visible in outline would divide the resolver ecology, with regulated link types answering to public specification and retention rules while commercial link types remain within the brand's control, reproducing inside the resolution layer the two-layer allocation described in this group's legal article. Whether such a settlement arrives by standard, by delegated act, or through litigation over a changed link is not presently determinable.
Limits of the assertion
The propositions an infrastructure standard does not establish differ in kind from those of a claim mark, but they may be stated in the same form.
A QR code powered by GS1 asserts nothing environmental. It is an identifier, and its presence on a package indicates data architecture rather than environmental performance, notwithstanding that its novelty and its association with transparency initiatives may, in marketing use, lend it a favourable connotation. Resolution asserts nothing about content quality: the standard governs how the address is constructed, not what the brand publishes at it, and a Digital Link resolving to an unsubstantiated claim is syntactically conformant. Sunrise 2027 asserts nothing about consumer behaviour, capability milestones carrying no implication as to whether shoppers scan; the stated-intent evidence and its limitations are treated in this collection's evidence theme, and the relationship between scanning infrastructure and scanning practice is not established by the milestone. Finally, the standard asserts no exclusivity: competing carriers, including the digital watermarks examined in the next article, RFID and NFC, occupy adjacent applications, and Digital Link's URIs are encodable across several of them.
Summary
GS1 Digital Link makes no claims, resolves no controversies and appears on no compliance calendar; it is nonetheless becoming the layer through which the arrangements catalogued in this theme are administered, including the localised disposal instruction, the digitalised EPR mark, the carrier-borne reuse system and the passport-linked disclosure. The 2027 milestone, as GS1 states it, is confined to scanners capable of reading both codes. The standard's wider significance lies elsewhere: in the resolver architecture that permits one package to answer multiple questions, and in the extended dual-marked period during which the linear barcode gives way to a successor designed for conditions the barcode did not anticipate.
The governance consequences of addressability are less immediately apparent in a standard that makes no claims. Where a package's identity resolves through infrastructure, the resolver's operator acquires a position that prior labeling regimes did not allocate to any single party: a printed label was readable by anyone, governed by the claims law of every jurisdiction in which it appeared, and controlled by no intermediary, whereas a resolved label passes through identification and resolution layers whose availability, neutrality and persistence some party must guarantee. The standard's custodian is a federated not-for-profit, which mitigates the question without dissolving it, since links cease to resolve, services are retired, and the label functions that this theme records migrating to the data layer will inherit whatever fragility that layer carries. An addressable package carries more information than a printed one; it is also, for the first time in the history of packaging identification, a package whose information depends on the continued operation of a service.
