International Telecommunication Union

The International Telecommunication Union (ITU) is the United Nations specialized agency for telecommunications and information and communication technologies, headquartered in Geneva, Switzerland. Founded in Paris on 17 May 1865 as the International Telegraph Union by twenty states, it is the oldest agency in the UN family and today counts 194 Member States and more than 1,000 companies, universities and international and regional organizations among its members.^{1 • 2}

Founding and early history

Before 1865, sending a telegraph message across a border meant stopping at the frontier and translating the message into the next jurisdiction's system. Regional agreements began to ease these barriers, and from 1 March to 17 May 1865 representatives of twenty sovereign states met in Paris at the first International Telegraph Conference. On 17 May they signed the first International Telegraph Convention, creating the International Telegraph Union, the first international organization dedicated to regulating and improving technology on a global scale.^{2 • 4} The conference also adopted a unified set of international telegraph regulations that harmonized tariffs, procedures, and technology across Europe and as far as its borders with Asia and Africa.⁴

A permanent secretariat. In 1869 the Union established its International Bureau in Bern, Switzerland, a central secretariat that collected, organized, and distributed information among member states; the secretariat relocated to Geneva in 1948.⁴ The 1868 Vienna conference had already decided to place the Union's headquarters in Bern, and the same period saw the start of the Telegraph Journal, the Union's publication, in 1869.⁷

The 1865 convention proved adaptable to later technologies. A Berlin conference in 1885 established the first international telephone regulations, followed by the first regulations for wireless telegraphy, that is radio communications, in 1906 at the International Radiotelegraph Conference in Berlin, which also saw worldwide adoption of the SOS emergency distress signal.^{4 • 7}

Modern status and structure

The organization took its present name, International Telecommunication Union, in 1934 and became a specialized agency of the United Nations in 1947.³ ITU is an intergovernmental organization in which governments, as Member States, and the private sector, as Sector Members, have well-defined rights and obligations and work together to coordinate telecommunication networks and services. Membership is open only to states and to legal entities such as corporations, organizations, associations, and academic institutions; individuals cannot join.^{5 • 8}

ITU's work is organized in three sectors:⁵

1. Radiocommunication Sector (ITU-R), which manages the global radio-frequency spectrum and satellite orbit resources to ensure their rational, equitable, efficient and economical use.
2. Telecommunication Standardization Sector (ITU-T), a forum for industry and government to develop interoperable international standards known as ITU-T Recommendations.
3. Telecommunication Development Sector (ITU-D), which fosters cooperation in delivering technical assistance and building telecommunication networks in developing countries.

The Plenipotentiary Conference is the Union's supreme organ and normally meets every four years; the next one, PP-26, is scheduled for 2026 and will set the direction of the Strategic Plan 2028-2031.^{3 • 9} A 48-member Council elected by the Conference meets annually in Geneva and governs in the interval between Plenipotentiary Conferences.³

Spectrum, satellite orbits, and standards

ITU allocates global radio spectrum and satellite orbits and develops the technical standards that allow networks and technologies to connect across borders.¹ The international treaty governing spectrum use is the ITU Radio Regulations, whose 2024 edition contains the complete texts adopted by the World Radiocommunication Conference of 1995 and revised by subsequent conferences, most recently WRC-23 in Dubai. The quadrennial World Radiocommunication Conference reviews and revises the Radio Regulations; WRC-27 will be held in Shanghai, China, preceded by the 2027 Radiocommunication Assembly.^{10 • 11}

ITU-R also frames the requirements for each generation of mobile technology. The 6G vision is handled in ITU-R under the official name "international mobile telecommunications (IMT) for 2030 and beyond," and ITU-R has adopted Integrated Sensing and Communication (ISAC) among the key usage scenarios for IMT-2030.^{12 • 13}

On standardization, ITU-T works alongside bodies such as ISO and the IEC; in December 2025 the three organizations jointly launched the Seoul Statement on ethical development practices for artificial intelligence.¹⁴

Funding

ITU depends on member contributions for its budget. Total budgeted revenues in 2026 were just above 160 million Swiss francs, equivalent to about 200 million US dollars at mid-2026 exchange rates. Membership fees supply 78.5% of the budget, paid by governments, companies, organizations, and academic institutions; cost-recovery activities such as publication sales and satellite filing fees account for 20%, and other revenues about 1.5%.⁶ Member States alone provide 68.4% of total revenue, with the United States the largest contributor at 35 units (CHF 11.1 million per year), followed by Japan at 30 units and Germany at 25 units.⁶

Role in internet governance

ITU's role in internet governance has been contested. Some governments, notably China and Russia, have advocated giving ITU more control over how the internet operates, while the multi-stakeholder model led by ICANN, the IETF, and other bodies coordinates the internet's address system and technical operations outside intergovernmental control.¹⁵ The 2022 election for ITU Secretary-General, held by secret ballot at the Plenipotentiary Conference in Bucharest, drew a US campaign for the American candidate Doreen Bogdan-Martin against a Russian candidate, amid debate over governments' role in internet standards.¹⁵ ITU also sets technical standards for data cables, including the subsea cables that carry most intercontinental internet traffic, though ownership and jurisdictional questions of cable consortia complicate its coordination role.¹⁶

Development work and the connectivity gap

ITU works to close the digital divide through universal connectivity and sustainable digital transformation, the two strategic goals Member States set for 2024 to 2027.¹ An estimated 2.2 billion people, largely in developing countries, remain unconnected.¹ Through ITU-D, the Union supports technical assistance and network development in developing countries, and its regulatory tools such as the ICT Regulatory Tracker and the G5 Benchmark underpin country reviews of collaborative digital regulation.^{5 • 17} The Union's Partner2Connect initiative had mobilized more than USD 73 billion in pledges as of 2025.¹⁸
