Identifier/numbering allocation and assignment

From ITUwiki

An array of global treaty instruments and other intergovernmental agreements for many decades have established governmental entities as significant communication network Identity Providers . These provisions establish the basis for a broad array of critical public identifier resources that include ICT, network, object, security, and radiocommunications identifiers ranging from E.164 telecommunication/telephone numbers, to public network provider identifers, to device identifiers, to all-encompassing ICT domain name systems like OIDs. These resources at the global level are maintained within the bureaus of international organizations like the ITU Telecommunications Standardization Bureau and the Radiocommunication Bureau, and increasingly include server-based query-response capabilities. Governmental agencies in turn are then responsible for resource management at regional or national levels - who in turn often allocate responsibilities to local governmental or private sector authorities. At regional and national levels, most countries also enact identifier resource management statutory legal provisions that provide for the allocation and assignment of these identifiers, including their use as network elements.
