Overview of One Window Service
Cambodia’s One Window Service Office, commonly known as OWSO, was established by the Royal Government of Cambodia through the Ministry of Interior in 2003 as part of a broader public administration reform effort aimed at making government services more efficient, transparent and accessible. The initiative was first launched as a pilot project in Battambang and Siem Reap under Decision No. 47 SSR dated June 11, 2003, with support from development partners including the European Union. The system was designed to allow citizens and businesses to access multiple administrative services in one location instead of visiting different government offices separately. More details are available through the official OWSO platform at OWSO Cambodia.
Following the success of the pilot phase, the government gradually expanded the One Window Service model nationwide under the leadership of the Ministry of Interior and the National Committee for Sub National Democratic Development.
The service now covers sectors such as land management, construction, transportation, business registration and other public administrative services at capital and provincial levels. In recent years, Cambodia has also accelerated the digital transformation of the system by introducing online applications and mobile banking integration to improve convenience and reduce processing times. Additional background information can be found through the General Department of Administration factsheet.
One Window Service Units See Strong Growth
Cambodia’s One Window Service Units handled more than 270,000 administrative services during the first four months of 2026, reflecting the government’s continued push to improve public service delivery and expand digital access across the country. The nationwide service network generated 48.45 billion riel, or around $12.11 million, in revenue as more citizens turned to streamlined administrative systems for faster and more convenient support.
The latest figures, released in a report by the General Department of Administration and submitted to the spokesperson team of the Ministry of Interior, highlight growing public reliance on these integrated service centers. The system is designed to simplify procedures by allowing citizens to access multiple government services in one place instead of visiting different offices.
Land and Transport Services Lead Demand
Among the 14 service sectors available through the One Window Service Units, land management, urban planning and construction recorded the highest demand with 88,438 services processed. Public works and transport followed closely behind with 87,198 services delivered during the same period.
The report shows that these sectors continue to play a critical role in Cambodia’s economic and urban development, particularly as construction activity, infrastructure projects and property related transactions remain active nationwide. In contrast, the commerce sector saw the lowest activity, with only two services recorded over the four month period.
The growing number of processed applications reflects increasing public confidence in the efficiency of the One Window Service framework. Citizens are increasingly seeking faster processing times and more transparent procedures when dealing with administrative matters.
Online Services Expand Across Provinces
The government has also accelerated the expansion of online administrative services in 12 target provinces, helping citizens access essential services remotely. The online system now supports services related to tourism, culture and fine arts, industry, science, technology and innovation, as well as agriculture, forestry and fisheries.
These digital services generated an additional 54.45 million riel in revenue, showing steady public adoption of online government platforms. The expansion is expected to reduce paperwork, minimize waiting times and improve accessibility for people living outside major urban centers.
Officials believe the move toward digital administration will help modernize Cambodia’s public sector while making services more accessible for citizens and businesses alike.
Government Pushes Digital Transformation
Recently, Sar Sokha officially launched a nationwide information system that allows all capital and provincial One Window Service Units to process applications and deliver administrative services online. Citizens can also access these services through banking mobile applications, creating a more convenient digital experience.
The Ministry of Interior said the modernization effort is aimed at improving the quality, speed and transparency of public service delivery. The digital system is designed to strengthen accountability while ensuring services are delivered in line with the established One Window Service mechanisms.
Sokha described the launch of the online platform as a major step forward in Cambodia’s digital reform journey. The initiative also supports the implementation of the Pentagonal Strategy Phase I under the leadership of Hun Manet, with the broader goal of building a fully digital government in the future.
Conclusion
The strong performance of Cambodia’s One Window Service Units during the first four months of 2026 highlights the country’s growing focus on efficient and technology driven public services. As digital platforms continue to expand nationwide, citizens are expected to benefit from faster, more transparent and more accessible government services. The continued modernization effort also signals Cambodia’s ambition to strengthen digital governance and improve public sector efficiency in the years ahead.
