1. Importance of Checking Company Name Availability
Before registering a company in Vietnam, business name lookup is the first important step. A name that is identical or too similar to another business can lead to legal risks, rejection of registration applications or trademark disputes later.
Checking the name also helps businesses protect their brand from the beginning, creating a professional impression with customers and partners. This is especially important for startups and companies planning to expand their market.

When choosing a company name in Vietnam, businesses must comply with the following legal requirements:
- Name structure: must include the business type + a distinct proper name. (Based on ArtHow to Check Company Name Availability in Vietnam Before Registrationicle 37, Law on Enterprises 2020)

- Language & characters: Vietnamese, foreign languages using Latin letters, numbers, and symbols are permitted. (Based on Article 37(3), Law on Enterprises 2020)
