TECRID, explained
What is a
TECRID?
TECRID stands for Test Evidence Credential Record Identifier. A TECRID is a permanent identifier for a laboratory-issued Test Evidence Credential: a structured digital record of what was tested, what the laboratory reported, who issued it, and whether the record has changed.

Purpose and function
Make the laboratory’s record portable—and still verifiable.
- 01The laboratory issues
The record captures results, units, methods, sample context, issuer identity, and the intended visibility.
- 02TECRID preserves
The registry verifies the issuer’s signature, fingerprints the exact record, assigns the identifier, and retains versions and corrections.
- 03Recipients resolve
A person or connected system uses the TECRID to retrieve the authorized current record and determine whether it is authentic, current, corrected, or revoked.
Who TECRID is for
One identifier across the evidence chain.
The same record can move from the issuing laboratory to the organizations that manufacture, certify, procure, regulate, research, or evaluate a product—without becoming an uncontrolled public PDF.
Laboratories
Issue authenticated, structured records and answer report-verification questions without repeatedly searching archives or confirming emailed PDFs.
Brands and suppliers
Receive reports in one evidence portfolio, preserve what the laboratory actually reported, and share only the records and SKUs they authorize.
Retailers, certifiers and government
Request and validate evidence at scale through identifiers, scoped sharing, CSV submissions, and APIs instead of collecting folders of PDFs.
Researchers and the public
Resolve public TECRIDs, verify their issuer and status, and see corrections without relying on a screenshot or detached document.
Fraud reduction
TECRID reduces opportunities for evidence fraud. It does not make fraud impossible.
Its job is to make a laboratory claim checkable at its source and to preserve the exact record that was issued.
See the documented market problem →- Inventing a laboratory report that the named laboratory never issued
- Changing values, units, methods, or sample context after issuance
- Presenting an obsolete version while hiding a correction or revocation
- Separating results from issuer identity and provenance
- That the submitted sample represented the entire lot
- That a method was suitable for every scientific or regulatory purpose
- That a result meets a safety, legal, or certification standard
- That every claim elsewhere in a supply chain is truthful
Global transparency
Evidence can cross borders without losing its source.
TECRID provides a common web identifier, structured schema, verification method, and API boundary that do not depend on one laboratory’s PDF format or one buyer’s software. As adoption grows, laboratories can issue once, organizations can reuse authorized evidence, and public records can be checked anywhere without forcing confidential findings into the open.
Direct answers
Common TECRID questions.
What does TECRID stand for?
TECRID stands for Test Evidence Credential Record Identifier. TEC is the Test Evidence Credential—the digital evidence record. TECRID is the permanent identifier assigned to that record.
Is every TECRID public?
No. A TECRID may be private, controlled for named recipients, or public. Assigning an identifier does not itself publish the underlying report or findings.
Can a brand issue its own laboratory TECRID?
A brand can place a historical report into private intake and ask the named laboratory to confirm it. A production laboratory-issued TECRID requires a verified laboratory, its reviewed signing key, and its signature over the record.
Does a TECRID prove that a product is safe or compliant?
No. It authenticates the evidence record and its history. It does not replace representative sampling, method suitability, accreditation, regulatory criteria, certification review, or expert interpretation.
How is a TECRID different from a DOI or ORCID?
A DOI persistently identifies a research output. An ORCID identifies a researcher. A TECRID persistently identifies a laboratory evidence record.
Who operates TECRID?
TEC Registry is an initiative of the Institute of Contaminant Standards, which develops the protocol, issuer rules, governance, and public-interest safeguards.
