To implement the telecommunications number storage planning enclosed with Circular No. 22/2014/TT-BTTTT dated December 22, 2014, the Ministry of Information and Communications has promulgated the area code change plan (hereinafter referred to as “the Plan”), particularly as follows:

To minimize possible negative impacts on businesses and service users and to assure the harmony of social interests and costs, the Plan must meet the following requirements:

a) Assure safety for telecommunications networks and information security before, during and after area code change;

b) Changing area codes must be quick and favorable for businesses and service users;

c) Take technical measures to minimize possible loss of communication before, during and after area code change by allowing service users to dial the old area code and new area code simultaneously during area code change; maintain notification sounds for an appropriate period of time after area code change;

d) Changes to area code should be in conformity with international practice;

dd) Area codes across the country must be changed and put into use in accordance with area codes planned in the telecommunication number storage planning enclosed with the Ministry of Information and Communications’ Circular No. 22/2014/TT-BTTTT dated December 22, 2014.

Change existing area codes of 59 out of 63 provinces, cities across the country (except area codes of four provinces Vinh Phuc, Phu Tho, Hoa Binh and Ha Giang) into new area codes as planned in the telecommunications number storage planning enclosed with Circular No. 22/2014/TT-BTTTT dated December 22, 2014. To meet the purposes and requirements as prescribed in Section 1, the area code change shall be divided into stages. Each stage consists of multiple steps, particularly as follows:

2.1. Division into stages

To ensure changing of area codes is quick and favorable for businesses and service users while meeting requirements for simultaneous dialing, the area code change is divided into three stages as follows:

a) Stage 1: Change area codes of 13 provinces: Son La, Lai Chau, Lao Kai, Dien Bien, Yen Bai, Quang Binh, Quang Tri, Thua Thien Hue, Quang Nam, Da Nang, Thanh Hoa, Nghe An, Ha Tinh;

b) Stage 2: Change area codes of 23 provinces: Quang Ninh, Bac Giang, Lang Son, Cao Bang, Tuyen Quang, Thai Nguyen, Bac Kan, Hai Duong, Hung Yen, Bac Ninh, Hai Phong, Ha Nam, Thai Binh, Nam Dinh, Ninh Binh, Ca Mau, Bac Lieu, Can Tho, Hau Giang, Tra Vinh, An Giang, Kien Giang, Soc Trang;

c) Stage 3: Change area codes of 23 provinces, cities: Hanoi City, Ho Chi Minh City, Dong Nai, Binh Thuan, Ba ria – Vung Tau, Quang Ngai, Binh Dinh, Phu Yen, Khanh Hoa, Ninh Thuan, Kon Tum, Dak Nong, Dak Lak, Lam Dong, Gia Lai, Vinh Long, Binh Phuoc, Long An, Tien Giang, Binh Duong, Ben Tre, Tay Ninh, Dong Thap.

2.2. Steps of each stage

To minimize possible loss of communications before, during and after area code change, each stage must consist of four steps as follows:

a) Make public announcement on domestic media, to telecommunications administration agencies of other countries, International Telecommunication Union at least 60 days before the area code change starts;

b) Take technical measures to enable simultaneous dialing for 30 days since the area code change starts;

For example: During this time, users may dial old area code 04.23456789 or new area code 024.23456789 to Hanoi City..

c) Maintain the notification sound for a minimum of 30 days (since the time of simultaneous dialing closes). During this time, any call using new area codes shall be normally processed and any call using old area codes shall be routed to the notification sound (in both Vietnamese and English for interprovincial, inter-network calls; and in English for international calls), particularly:

c1.) For domestic calls, the notification sound shall come from any telecommunication enterprise from which a call is initiated by the switchboard.

- The notification sound in Vietnamese: “Xin thông báo: mã vùng của (tên tỉnh/thành phố) đã thay đổi. Đề nghị Quý khách quay số lại, thay (mã vùng cũ) thành (mã vũng mới)”

- The notification sound in English: “Please note that the area code of (name of Province/City) has been changed. Please redial, replacing (old area code) with (new area code)” For example: A user in Vietnam who dials the old area code 04.23456789 to Hanoi City shall receive a notification sound in Vietnamese: “Xin thông báo: mã vùng của TP. Hà Nội đã thay đổi. Đề nghị Quý khách quay số lại, thay 4 thành 24” and in English: “Please note that the area code of Ha Noi City has been changed. Please redial, replacing 4 with 24”.

c2.) For international incoming calls, the gateway of an international incoming call service providers shall deliver the notification sound.

The notification sound in English: “Please note that the area code of (name of Province/City) has been changed. Please redial, replacing (country code+old area code) with (country code+new area code)”

For example: A user outside Vietnam who dials the old area code +84.4.23456789 to Hanoi City shall receive a notification sound “Please note that the area code of Ha Noi City has been changed. Please redial, replacing 844 with 8424”.

d) Stop maintaining the notification sound: Calls shall be successful processed only through new area codes.

To ensure changing of area codes is quick and favorable for businesses and service users, step a aforementioned should be implemented for all three stages.

2.3. Duration of area code change implementation

To assure safety and convenience for users, the changing of area codes should start on Saturday or Sunday, avoid public holidays, Tet holidays, particularly as follows:
