To look up a tax identification number, first determine whether you are looking for a business, subsidiary, or your own file, and whether it has a tax identification number, legal name, or unique identifier.<\/strong> If you already have a business registration number, start by checking the tax authority's lookup portal; if you only have the name, find the correct legal entity on the business registration portal and then compare it with the tax portal. Individuals can check their records through the official tax channels, or use the old registration number on the publicly available form when needed for verification.<\/p>\n

The use of personal identification numbers instead of tax identification numbers has been implemented since July 1, 2025. From July 1, 2026, Article 11 of the Tax Administration Law 108\/2025\/QH15 stipulates that the tax identification number of individuals, households, and business households and individuals is the personal identification number within the scope of the law; Circular 90\/2026\/TT-BTC provides detailed regulations on registration, transition, and status of tax identification numbers. The search results should include the name, address, status, and time of display; a single number found does not automatically prove a valid transaction or invoice.<\/p>
