FindBase is an independent public-data search platform that helps users find, check, compare, and explore information from multiple public sources. Its data is continuously cross-referenced and updated. The service focuses on Vietnamese business and administrative information, covering more than 2.3 million tax identification numbers and the current system of 34 provinces and cities.

Users can search a company’s tax number to view its registered name, address, operating status, business lines, legal representative, and relationship to a parent entity. FindBase also provides administrative-boundary lookup tools, including commune and ward codes, comparisons between former and current administrative units, and mappings from old units to new ones. Where public records do not provide enough detail to identify a single new unit, the platform indicates the uncertainty and lists possible matches.

FindBase presents addresses across both administrative systems to help users interpret older records. It describes itself as a lookup tool, not an official government portal, and advises users to verify information with the tax authority when legal confirmation is required.
