When purchasing dietary supplements, medicines, cosmetics, or other health-related products, many consumers first check whether the product has a Thai FDA registration number. This helps provide confidence that the product has been authorized in accordance with Thai regulations.
However, a Thai FDA registration number is only one of several factors consumers should consider. It does not guarantee that a product is completely safe or suitable for everyone. Understanding what a Thai FDA registration number means—and what it does not—can help you make more informed purchasing decisions.
The Thai Food and Drug Administration (Thai FDA) is a government agency under the Ministry of Public Health responsible for regulating health products before and after they enter the market. Its role is to ensure that these products comply with applicable laws and regulatory standards.
Products regulated by the Thai FDA include:
Food
Medicines
Cosmetics
Herbal products
Medical devices
Certain household hazardous substances
The Thai FDA's responsibilities extend beyond issuing registration or authorization numbers. It also evaluates product applications, inspects manufacturing facilities, regulates product labeling and advertising, and monitors the quality and safety of products available on the market.
Before purchasing health-related products such as dietary supplements, cosmetics, or medicines, verifying the Thai FDA registration number is one way to increase confidence that the product has been authorized under Thai regulations.
Start by looking for the Thai FDA mark or registration number displayed on the product label or packaging. You can then use this number to search the official Thai FDA database.

You can also search the database using the product name.
When verifying a product, do not rely solely on whether a result appears in the database. Compare the information shown in the system with the details on the product label, including:
Product name
Product category
License holder, manufacturer, or importer
Registration or authorization number
Product status (if available)
If the information does not match or the product cannot be found, verify the details again or contact the Thai FDA before purchasing or using the product.
Keep in mind that verifying a Thai FDA registration number does not prove that a product is genuine or guarantee that it is 100% safe. It simply confirms that the product information can be verified through the official database maintained by the regulatory authority.
You can verify product information through the official Thai Food and Drug Administration (Thai FDA) website.


Thai FDA registration or authorization numbers are commonly found on health products regulated by the Thai Food and Drug Administration. The type of registration number and how it is displayed may vary depending on the product category.
Products that commonly display a Thai FDA registration or authorization number include:
Packaged food and beverages
Dietary supplements
Medicines
Cosmetics
Medical devices
Herbal products
Certain hazardous substances, such as insecticides or disinfectants regulated by the Thai FDA
However, each product category is subject to different regulatory requirements, and not all products are required to display the same type of registration number. Therefore, the absence of a Thai FDA registration number on certain products does not necessarily mean the product is illegal. The applicable requirements depend on the product category and relevant regulations.
A Thai FDA registration number is more than just a number printed on a product label. It provides information that helps consumers verify the product before making a purchase.
Some of the key benefits include:
Confirming that the product information is available in the official Thai FDA database
Identifying the license holder, manufacturer, or importer
Increasing confidence when purchasing products from reliable sellers
Serving as a reference when making inquiries, submitting complaints, or reporting product-related issues
Although a Thai FDA registration number is an important source of information, consumers should also review other details on the product label, such as directions for use, warnings, and the expiration date before making a purchase or using the product.
While a Thai FDA registration number can help increase consumer confidence, it should not be interpreted beyond its intended purpose. Having a Thai FDA registration number does not mean that:
The product will work for everyone
The product is safe for every user
It can replace advice from a doctor or pharmacist
All advertising claims or customer reviews have been approved by the Thai FDA
Consumers do not need to read the product label, directions for use, or warnings
Before purchasing or using any health-related product, consumers should verify the Thai FDA registration number, carefully read the product label, follow the directions for use, and purchase products only from reputable sellers.
