(Main)Supply chain interoperability and integration — Part 100: Verification of supply chain data
- Abstract
This document supports supply chain interoperability and integration and provides the fundamental structure for exchanging verified data in an industrial internet. Identifiers, like part numbers, are the shorthand for datasets throughout the supply chain. This document provides methods to verify identifiers and datasets behind identifiers used in the supply chain, specifically the format of and automated request types (verify, resolve, and search) and replies to those requests. The following are within the scope of this document: the syntax requirements and application protocol interface (API) for a request and response to a request for the verification of identifiers formatted in accordance with ISO 8000-115 (verify); the syntax requirements and API for a request and response to a request for a dataset of an identifier formatted in accordance with ISO 8000-115 (resolve); the syntax requirements and API for a request and response to a request to search for an identifier formatted in accordance with ISO 8000-115 given characteristic data (search). The following are outside the scope of this document: the methods used for the resolution of identifiers by the identifier issuer; the data elements required for resolution of identifiers.

ISO 25500-100:2026 is an ISO standard for supply chain interoperability and integration. It specifies how verified supply chain data is requested and replied to in an industrial internet, using ISO 8000-115 identifiers for verify, resolve, and search exchanges between registered parties. It is written for organizations and systems that exchange part numbers, datasets, and item characteristic data across the supply chain.
What does ISO 25500-100:2026 specify?
ISO 25500-100:2026 specifies the request and response syntax and the application protocol interface (API) for verified supply chain data exchanges. Its focus is the exchange pattern around ISO 8000-115-formatted identifiers, not the issuer’s internal resolution method.
The document is organized into:
- Clause 1, Scope
- Clause 2, Normative references
- Clause 3, Terms and definitions
- Clause 4, Supply chain data: verification, resolution, and search processes
- Clause 5, Conformance
- Annex A, Informative document identification
Annex A gives document identification information for use in an open system.
What are the key requirements of ISO 25500-100:2026?
ISO 25500-100:2026 defines three automated exchange patterns in Clause 4: verify, resolve, and search. In practice, these are the core services an implementation must support when exchanging verified supply chain data.
- Clause 4.1 frames the exchanges as part of the industrial internet and routes them through a prefix name server (PNS). The prefix records expose the verified international business identifier (IBID) while keeping electronic address information confidential, so parties can identify who is sending or answering without revealing unnecessary contact details.
- Clause 4.2.1 requires a verification request to go to the confidential address of the identifier issuer from the ISO 8000-115 prefix record in the PNS. The request contains the requestor’s registered prefix, the respondent’s registered prefix, and the identifier to be checked, so the exchange is tied to specific registered entities and a specific identifier.
- Clause 4.2.2 limits the verification reply to a small set of outcomes: syntax error, data error, request denied, timed out, or verified. This makes the service machine-readable and easy to automate in procurement or master data checks.
- Clause 4.3.1 uses the same request routing pattern for resolution, again with registered prefixes and the identifier to be resolved. This is the step used when the requester needs the dataset that the identifier represents.
- Clause 4.3.2 requires the resolution reply to be in ISO 8000-114 format and to return either an error status or data in .idf. That matters because the reply is not just a yes/no answer - it delivers the structured dataset the identifier stands for.
- Clause 4.4.1 defines search by characteristic data instead of by an identifier alone. The requester sends item characteristic data, which lets the issuer look for matching identifiers when the identifier is not yet known.
- Clause 4.4.2 requires the search reply to return one or more quality identifiers, or one of the same error/status conditions. In practice, this supports identification from attributes rather than from an existing part number.
- Clause 5 states conformance in terms of applying the request and reply rules in 4.2.1, 4.2.2, 4.3.1, 4.3.2, 4.4.1, and 4.4.2. A system conforms when it follows these message rules end to end.
What terms does ISO 25500-100:2026 define?
ISO 25500-100:2026 relies on the terms and definitions in ISO 25500-2, and several terms are central to its processes.
- Industrial internet - the trusted data-sharing environment used here for exchanging verified supply chain data.
- Prefix name server (PNS) - the service used to route requests through prefix records and obtain the confidential address of the issuer.
- International part number (IPN) - a part number in ISO 8000-115 format that can be resolved through the prefix record.
- International business identifier (IBID) - the verified legal identity of the prefix owner shown in the prefix record.
- Quality identifier - the identifier returned or checked in the supply chain verification and search processes.
- Characteristic data - the item attributes sent in a search request to help identify a matching identifier.
Who uses ISO 25500-100:2026?
ISO 25500-100:2026 is used by organizations that need automated identifier verification and data exchange across supply chains. That includes manufacturers, distributors, logistics providers, procurement teams, warehousing operations, and software developers building supply chain integration services.
It is also relevant to identifier issuers and to organizations working on know your customer (KYC), know your supplier (KYS), and know your item (KYI) processes. For buyers and quality managers, it supports checking that a part number or dataset is correct before it is used in a purchase order or other business process.
Which standards are used with ISO 25500-100:2026?
ISO 25500-100:2026 refers to several related standards that support its exchange model.
- ISO 8000-115 - defines the quality identifier format and the syntactic, semantic, and resolution rules used throughout the document.
- ISO 8000-114 - provides the portable data format used for the resolve reply.
- ISO 25500-2 - supplies the terms and definitions used in this part.
- ISO 25500-1 - is the basis for the industrial internet model referenced in the introduction and Clause 4.
- ISO/IEC 8824-1 - defines the ASN.1 notation used for the Annex A object identifier.
- ISO 10303-1 - defines the meaning of the Annex A object identifier value.
What does the ISO 25500-100:2026 document contain?
ISO 25500-100:2026 contains a scope, normative references, terms and definitions, and a process clause for three supply chain exchanges. Clause 4 lays out the request and reply structure for verification, resolution, and search, including the fields that must be present and the allowed reply statuses.
The document also includes a conformance clause that ties compliance to the specified request and reply behavior. Annex A gives an informative document identifier for use in open information systems, and the bibliography points to the related standards used in the model.

Introduction
The supply chain needs standard solutions to increase the effectiveness, efficiency, and security of business
through greater interoperability and integration across applications, facilities, companies, and borders.
Supply chain data is understood through identifiers; identifiers (for parts, products, services, materials,
certifications, legal entities, etc.) are found in every process of the supply chain from procurement to
warehousing, making, order processing, and logistics. Identifier resolution is essential to meeting know
your customer (KYC), know your supplier (KYS), and know your item (KYI) requirements. For interoperable,
integrated, sustainable, and efficient supply chains, identifiers and the datasets they represent need to be
verified through automated processing.
ISO 8000-115 describes a quality identifier as definitive, resolvable, and consisting of a prefix element
to represent the legal entity that issued the identifier and the identifier element assigned by the owner
to represent the object and the data describing it, along with any use restrictions. A part number in
ISO 8000-115 format, called an international part number (IPN), can be resolved through looking up the
prefix owner in a prefix record in an ISO 8000-115 prefix name server (PNS) and the addresses in that prefix
record can be used to request resolution of the part number.
