Communication Network for the August Revolution In preparation for the General Uprising, from August 13 to 15, 1945, the Central Committee of the Indochinese Communist Party held a meeting in Tân Trào and issued a resolution on launching a nationwide general uprising. In Hanoi, amid the revolutionary fervor, communication between Hanoi and the Central Committee based in Việt Bắc became more crucial than ever. Assigned with the critical task of maintaining this link, individuals worked tirelessly to find spare parts, repair, restore, and assemble equipment such as telephones, radios, and telegraphs, ensuring communication readiness for the August Revolution

Establishment of Hanoi Post Office On October 10, 1954, in accordance with the Geneva Accords, the capital Hanoi was liberated. On that very day, revolutionary communication workers took over the Hanoi Post Office, including the telegraph and telephone systems left by the French. This date later became recognized as the official founding date of Hanoi Post Office.

Launch of Hanoi Automatic Telephone Exchange On May 1, 1960, the 3,000-line Hanoi Automatic Telephone Exchange was completed and officially put into operation. This was the first automatic telephone exchange in Hanoi and Northern Vietnam, marking a technical leap in telecommunications. During the resistance against the U.S., Hanoi’s telephone operators and line maintenance staff heroically ensured the security of the communication network.

With the complete liberation of the South and national reunification in 1975, Hanoi set goals to modernize its communication network, enhance systems, and expand telephone services to districts and communes. In 1976, the building at 75 Đinh Tiên Hoàng (now VNPT Hanoi’s headquarters) was constructed. On September 2, 1978, the building’s rooftop clock chimed for the first time with the melody of “Praising President Hồ Chí Minh,” becoming a symbol dear to Hanoi’s citizens

The Directorate General of Post established the Hanoi Telephone Company (ĐTHN) with 400 employees. At that time, Hanoi Post had three main companies: Hanoi Telephone Company, Long Distance Telephone Company, and Telegraph Company. ĐTHN was tasked with managing, operating, and marketing telephone networks in the capital, setting the foundation for modernization. In the same year, staff self-installed an automatic telephone exchange, increasing capacity to 9,000 lines—a major upgrade from the long-standing 6,000 lines

On November 15, 1990, the E10B digital telephone exchange was completed and launched in Hanoi, marking a breakthrough in switching technology. Alongside the Alfa V Telex exchange and technologies like fiber optics, digital microwave, and Intelsat A, Hanoi’s network began integrating with the international digital telecommunications system

April 1995: The Prime Minister issued Decision 249/TTg to establish the Vietnam Posts and Telecommunications Corporation (VNPT). •    June 1996: VinaPhone mobile service launched in Hanoi. •    December 1997: Internet service officially launched in Hanoi

Following two rapid development phases, Hanoi’s telecommunications sector entered a stage of integration and development. Infrastructure continued to be built to enable multi-service offerings, meeting the city’s growing ICT needs. • 2001: Hanoi Post Office received the Third-Class Independence Order. • 2003: Launch of high-speed MegaVNN Internet. • 2004: Hanoi Post Office was awarded the title “Hero of the People’s Armed Forces.”

On December 6, 2007, VNPT’s Board of Directors issued Decision No. 625/QĐ-TCCB/HĐQT establishing VNPT Hanoi. From January 1, 2008, VNPT Hanoi became a dependent economic unit of VNPT, operating in telecommunications and IT. This was part of VNPT’s restructuring to separate postal and telecom operations for mutual development

On January 27, 2011, VNPT Hanoi received the Second-Class Independence Order for achievements from 2005 to 2009. In May 2010, VNPT launched Fiber VNN optical Internet service in Hanoi

In 2014, VNPT Hanoi implemented a successful restructuring strategy based on specialization, differentiation, and efficiency: •    Phase 1: Nine telecom centers were established based on the former three telephone companies. •    Phase 2 (2015): The Customer Service Center was separated to form VNPT Hanoi Business Center under Vinaphone

• December 19, 2020: VNPT became the first network provider to commercially launch VinaPhone 5G in Hanoi and Ho Chi Minh City, marking Vietnam’s entry on the global 5G map. • 2021: VNPT Hanoi received the First-Class Independence Order for outstanding achievements from 2010 to 2020.

Trusted by the Hanoi government, VNPT has been tasked with building the digital infrastructure for e-government and IT applications. On February 9, 2023, the Hanoi City Reporting Information System and Centralized Document Management System, developed by VNPT, were officially launched by the city government. This marked VNPT Hanoi’s initial success in the digital transformation journey
