Verifiable credentials
90X2 certifications, listings, and approvals
Each record below covers this specific model, grouped by what kind of credential it actually is — a third-party certification is not the same claim as a listing, a carrier approval, a manufacturer attestation, or an independent test engagement. Where an identifier is shown it is the one issued by the organization named, so the claim can be checked against their own record. Where it reads “identifier not published”, the record is confirmed by DataRemote's records but its identifier has not yet been published here.
