If the official seal is not stamped with words, it is considered valid. The official seal is the proof of the identity and power of the enterprise, and it has legal effect. Documents stamped with a company's seal are valid documents protected by law, and it also means that the company bears legal responsibility for the content of the document. Therefore, companies, public institutions or other organizations must establish a strict seal management system and be cautious about stamping seals on blank paper to avoid unnecessary trouble or losses caused by malicious people. There will be differences when the words are later written on the official seal. As for whether it is valid, it depends on whether the other party can approve it. The danger of stamping the official seal on white paper casually is because the official seal is a symbol of the sealing unit and represents the sealing unit. The official seal is stamped on a piece of white paper, which can be used by people with ulterior motives to add content and obtain illegitimate benefits by illegal means. The unit that bears the responsibility is the unit that owns the official seal.

The official seal can only be stamped on the unit signature below the written content to express confirmation of the stamped content.
