How to Read a 13-Digit Thai FDA Registration Number

Now that we understand which regulated categories require or are exempt fromhaving the Thai FDA (อย.) mark Many people wonder what the long string of digits inside a Thai FDA (อย.) emblem actually stands for. That official sequence printed inside the FDA logo is known as the “Food Serial Registration Number (Food Serial No.)” —a structured 13-digit regulatory code encoded with five specific verification components:  

Breakdown of the 13-Digit Thai FDA (อย.) Registration Number

  1. Group 1 (First 2 Digits) Indicates

• Province & Geographic Location of the Establishment 
• A 2-digit provincial code corresponding to the province where the factory or importer is registered.

2. Group 2 (3rd Digit) Indicates

• Facility Type & Approving Regulatory Authority
• A single status digit identifying whether the product is domestically produced or imported, and by which authority:

               Digit 1 Food manufacturing facility licensed directly by the Central Thai FDA (อย.).

               Digit 2 Food manufacturing facility licensed by the Provincial Public Health Office.                Digit 3 Food importing facility licensed directly by the Central Thai FDA (อย.).                Digit 4 Food importing facility licensed by the Provincial Public Health Office. 3. Group 3 (Digits 4–8) Indicates

• Licensed Facility Serial Number & Year of Establishment Approval
• A 5-digit code where the final two digits reflect the Thai Buddhist Era year in which the facility permit was granted.

4. Group 4 (9th Digit): Single-digit code identifying the specific regulatory division issuing the product serial approval. 5. Group 5 (Final 4 Digits) Indicates Sequential Product Filing Number Issued to That Specific Facility Represented by the last 4 digits on the right of the serial number.   By contrast, non-food health categories (such as cosmetics) do not display the Thai FDA mark but must print an official Notification Number (Cosmetic Notification No.) on packaging.

• Wondering What the Thai FDA (อย.) Mark Means?
• Which 4 Product Categories Are Exempt from the Thai FDA (อย.) Mark? 

 

What Does a Cosmetic Notification Number Look Like?

A Notification Number indicates formal “Product Notification (Jod-Jaeng)” recorded inside the Thai FDA (อย.) registry, primarily governing the category of “Cosmetics & Skincare Products” to trace the importer, manufacturer, and approved formula origin (though it verifies compliance rather than product efficacy).      1. Group 1 (First 2 Digits) Indicates

• Province & location of the notified business premises (2 digits)
• A 2-digit provincial code corresponding to the province where the factory or importer is registered.

2. Group 2 (3rd Digit) Indicates 

• Establishment category & approving authority:
• Digits 1–4 denote facility type:

               Digit 1 1 — Domestic manufacturer approved by Central Thai FDA                Digit 2 2 — Domestic manufacturer approved by Provincial Office                Digit 3 3 — Importer approved by Central Thai FDA                Digit 4 4 — Importer approved by Provincial Office 3. Group 3 (Digits 4–8) Indicates

• Last 2 digits of the Buddhist Era approval year 
• For example, “39” represents B.E. 2539 (1996). 

4. Group 4 Indicates 

• Sequential approval number assigned to the registered cosmetic item.

  Even when a label displays a Thai FDA (อย.) number, consumers and distributors should always verify the 13-digit serial against the official Thai FDA database to ensure it is authentic and not misused.
