Concepts

This case-sensitive code system http://terminology.hl7.org/v2plusvocab/CodeSystem/UniversalIdTypeV120 defines the following codes:

CodeDisplayDefinitionversion introducedcommentDeutsch (German, de)
CLIA Clinical Laboratory Improvement Amendments Clinical Laboratory Improvement Amendments. Allows for the ability to designate organization identifier as a "CLIA" assigned number (for labs) 2.7 Allows for the ability to designate organization identifier as a “CLIA” assigned number (for labs)
CLIP Clinical laboratory Improvement Program Clinical laboratory Improvement Program. Allows for the ability to designate organization identifier as a "CLIP" assigned number (for labs).  Used by US Department of Defense. 2.7 Allows for the ability to designate organization identifier as a “CLIP” assigned number (for labs). Used by US Department of Defense.
DNS Domain Name System An Internet host name, in accordance with RFC 1035; or an IP address. Either in ASCII or as integers, with periods between components ("dotted" notation). 2.3 An Internet host name, in accordance with RFC 1035; or an IP address. Either in ASCII or as integers, with periods between components (“dotted” notation).
EUI64 IEEE 64-bit Extended Unique Identifier IEEE 64-bit Extended Unique Identifier is comprised of a 24-bit company identifier and a 40-bit instance identifier. The value shall be formatted as 16 ASCII HEX digits, for example, "AABBCC1122334455". The 24-bit company identifier, formally known as 2.7 IEEE 64-bit Extended Unique Identifier is comprised of a 24-bit company identifier and a 40-bit instance identifier. The value shall be formatted as 16 ASCII HEX digits, for example, “AABBCC1122334455”. The 24-bit company identifier, formally known as Organizationally Unique Identifier (OUI-24), is guaranteed to be globally unique. The 40-bit extensions are assigned by manufacturers. This identifier is often used in equipment interfaces (e.g., “MAC” address format for IPv4 & IPv6). [See http://standards.ieee.org/regauth/oui/tutorials/EUI64.htmlfor a detailed explanation of the format.]OUI-24 values are administered by the IEEE Registration Authority.
GUID globally unique identifier Same as UUID. 2.3 Same as UUID.Retained for backward compatibility only as of v2.7; use UUID instead GUID
HCD CEN Healthcare Coding Identifier The CEN Healthcare Coding Scheme Designator 2.3 The CEN Healthcare Coding Scheme Designator. Retained for backward compatibility only as of v2.7; does not identify Assigning Authorities
HL7 HL7 registration schemes HL7 registration schemes 2.3 Retained for backward compatibility only as of v2.7; HL7 assigns ISO OIDs for Assigning Authorities
ISO ISO Object Identifier An International Standards Organization Object Identifier (OID), in accordance with ISO/IEC 8824. Formatted as decimal digits separated by periods; recommended limit of 64 characters 2.3 An International Standards Organization Object Identifier (OID), in accordance with ISO/IEC 8824. Formatted as decimal digits separated by periods; recommended limit of 64 characters

N Local These are reserved for locally defined coding schemes. 2.3 Locally defined coding entity identifier.Retained for backward compatibility only as of v 2.8
Random Random Usually a base64 encoded string of random bits.<p>Note: Random IDs are typically used for instance identifiers, rather than an identifier of an Assigning Authority that issues instance identifiers 2.3 Usually a base64 encoded string of random bits.Retained for backward compatibility only as of v2.7; equivalent to a locally defined entity identifier scheme; use L. M, or N instead. Note: Random IDs are typically used for instance identifiers, rather than an identifier of an Assigning Authority that issues instance identifiers
