The Public Technical Identifiers (PTI) is the organization responsible for the operation of the IANA Functions, which primarily includes coordinating the Internet's unique identifiers. The PTI is an affiliate of ICANN, with ICANN being the sole member.
The PTI was founded in August 2016 as part of the implementation of the IANA Stewardship Transition. It's formation was designed to meet the ICG's recommendation to form a new legal entity to perform the IANA Functions, which was included in the proposal submitted to the NTIA on 10 March 2016.  It began performing the IANA Functions on behalf of ICANN in October 2016, immediately after the IANA function contract with the NTIA expired.
PTI is responsible for the operational aspects of coordinating the Internet’s unique identifiers and maintaining the trust of the community to provide these services in an unbiased, responsible and effective manner.
On 14 March 2014, the NTIA announced that it intended to relinquish its oversight of the IANA functions in favor of the global multistakeholder community and instructed the community to develop a proposal for the transition. During the development of this proposal, ICANN Accountability became an important issue. Prior to the transition, IANA was an internal department within ICANN that acted as the IANA functions operator (IFO). In order to establish a clearer separation between the technical and policy making functions, the proposal submitted by the ICG recommended that a separate legal entity take over the role of IFO. At the time this was referred to as Post-Transition IANA, but later became known as Public Technical Identifiers, both of which share the acronym PTI. The CWG-Stewardship recommended creating PTI as a separate legal entity to allow the possibility of separation from ICANN in the future and to allow for ICANN and PTI to enter into a contract.
Five members comprise the PTI board of directors. Together, they should represent diverse regions and understand the operation of generic top-level domain registries and registrars, country code top-level domain name registries, IP address registries, Internet technical standards and protocols, and policy implementation procedures. Three of its members must be employed by ICANN or PTI and have been nominated by a member, and two persons must be employed by neither ICANN nor PTI; they have to be nominated by ICANN’s NomCom. No official of a national government or a multinational entity established by treaty may serve as a PTI Director. No person who serves on any Supporting Organization Council or Advisory Committee shall simultaneously serve as a PTI Director.
