After the recent adjustment and merger of administrative boundaries, the address of the head office of the enterprise in Yen Hoa Ward has officially changed. This leads to a problem that the address information on the Business Registration Certificate of enterprises operating in the area no longer coincides with the new actual address. Therefore, many businesses need to carry out procedures for changing business registration. Viet An Law would like to guide the above procedure through the article below.

Specifically, Official Letter 4370/BTC-DNTN has clarified the following three contents.
- Firstly, in terms of legal validity: All types of Certificates that have been issued (including Business Registration Certificates, Certificates of Registration of Business Households, Cooperatives, and Certificates of Operation of Branches/ROs/Business Locations) remain legally valid and continue to be used normally by enterprises.
