Vietnam - Shared Short Code Requirements and Restrictions


The regulations in Vietnam caters and covers all of the Mobile Payment types, that includes Premium SMS BillingStandard Rate Services and Short Codes. 



Ministry of Information and Communications of the Socialist Republic of Vietnam

The political psychology of a country that fought for so long, so bitterly and so recently for its independence with close neighbors is unlikely to change quickly. The current government sees the importance of greater integration with the world economy and is taking calculated measures to increase the pace of reform. In an effort to comply with WTO stipulation for an independent regulator, the Directorate General of Posts and Telecommunications (DGPT, 1993) was replaced by the Ministry of Posts and Telematics (MPT) in 2002. The MPT is responsible for sector liberalization and for guiding the dismantling of VNPT’s monopoly (who were a major carrier in Vietnam). It was mirrored by the compilation of the Post & Telecommunications Ordinance which also came into force in 2002, the first professional legal document governing the posts and telecoms sectors issued by Vietnam’s legislative body. It covers management efficiency, the creation of a fair and legal environment for enterprises and the protection of consumer interests.

Ties between the MPT ( and VNPT remain cozy, creating questions about MPT’s independence and effective power. In reality, VNPT remains a hugely powerful force, sorely testing the independence and fairness of the regulator and its ability to curb VNPT’s influence. The MPT minister, Dr. Do Trung Ta, sits on the Communist Party's central committee.

According to a market note from The Economist Intelligence Unit, the Standing Committee of the National Assembly approved Ordinance 43 on May 25, 2002 to provide a foundation for improved transparency by requiring publication of interconnection agreements, reference interconnection offers and general licensing criteria, as well as requiring interconnection regulations to be based on transparent rules. The ordinance has been unevenly applied. Competitors have had difficulty getting interconnection. Additionally, radio frequency bands have not published and the terms and conditions of individual licenses are opaque.


Vietnam and the U.S. signed a Bilateral Trade Agreement (BTA) in July 2000 that, among other issues, defines a schedule for direct foreign investment in telecommunications services and sets the stage for conversion of BCCs to equity joint ventures. The agreement calls for Vietnamese partners to retain a 51 percent equity share. Under the BTA agreement, which applies to all countries that have normal trading relations with Vietnam, the schedule for sector opening was as follows:

December 2003 Value added services (e-mail, voice mail, online information)

December 2004 ISP services

December 2005 Mobile cellular services

December 2007 Fixed line services


These are numerous reference and legislation on the MTP online portal, for example 'Decree No. 90/2008/ND-CP date August 19, August, 2008 of the Government against spam.'

Originating in what is now southern China and northern Vietnam, the Vietnamese people pushed southward over 2 millennia to occupy the entire eastern sea coast of the Indochinese Peninsula. Vietnam has 54 ethnic groups; ethnic Vietnamese or Kinh constitute approximately 85% of Vietnam's population. The next largest groups are ethnic Tay and Thai, which account for 1.97% and 1.79% of Vietnam's population and are concentrated in the country's northern uplands. 

With a population of more than 900,000, Vietnam's Chinese community has historically played an important role in the Vietnamese economy. Restrictions on economic activity following reunification of the north and south in 1975 and a general deterioration in Vietnamese-Chinese relations caused increasing anxiety within the Chinese-Vietnamese community. As tensions between Vietnam and China reached their peak in 1978-79, culminating in a brief but bloody war in February-March 1979, some 450,000 ethnic Chinese left Vietnam by boat as refugees (many officially encouraged and assisted) or were expelled across the land border with China. 

Other significant ethnic minority groups include central highland peoples (formerly collectively termed Montagnards) such as the Gia Rai, Bana, Ede, Xo Dang, Gie Trieng, and the Khmer Krom (Cambodians), who are concentrated near the Cambodian border and at the mouth of the Mekong River. Taken collectively, these groups made up a majority of the population in much of Vietnam's central highlands until the 1960s and 1970s. They now compose a significant minority of 25% to 35% of the provinces in that region.

Vietnamese is the official language of the country. It is a tonal language with influences from Thai, Khmer, and Chinese. Since the early 20th century, the Vietnamese have used a Romanized script introduced by the French. Previously, Chinese characters and an indigenous phonetic script were both used.
