OEKO-TEX Certification Number is the certificate number a textile brand receives when its products pass OEKO-TEX testing, such as STANDARD 100. On Target+ it is optional, available on textile categories, and displays on the product detail page so shoppers looking for tested textiles can verify the claim.
The rules
| Rule | Value |
|---|---|
| Required | No |
| Categories | Category-specific; appears on textile categories that carry OEKO-TEX attributes |
| Level | Parent listing, once per style |
| Length | Up to 255 characters |
| Content | The certificate number exactly as printed on your certificate or label |
Enter the number alone, copied character for character from the certificate. Do not add the word "certified", the standard name or the institute name; the standard belongs in your description and the institute has its own field, OEKO-TEX Institution. Leave the field blank if the product is not certified; a certification number a shopper cannot verify is a claim you have to stand behind.
Examples
| Value | Verdict | Reason |
|---|---|---|
| 21.HUS.12345 | Good | A certificate number as printed, nothing added |
| 21.HUS.12345 STANDARD 100 by OEKO-TEX | Weak | The standard name is not part of the number |
| Certified | Weak | Not a number, cannot be verified |
| OEKO-TEX | Weak | Names the organization, not the certificate |
The numbers above are invented to show the shape of a value; use the one on your own certificate.
Common mistakes
- Entering a supplier's certificate number when the finished product is not covered by it. Certificates cover specific articles; the finished garment must be within scope.
- Filling the field with an expired certificate. Check the validity date before you list.
- Confusing this field with the MADE IN GREEN product ID, which goes in OEKO-TEX Institution.
How Osello fills this field
Osello sets this once on the parent listing and every variant inherits it. The value comes from your source product data, typically a Shopify metafield or a line in the description that states the certificate number. Because the field is optional and the number cannot be inferred, Osello leaves it blank when the source has no certificate number rather than composing one. See how Osello AI fills listing fields and the Target+ field directory.
Frequently asked questions
Is the OEKO-TEX Certification Number required to list on Target+?
No. It is optional, and only relevant when the product carries an OEKO-TEX certification. Listings without it submit normally.
Should the value include the standard name, such as STANDARD 100?
No. Enter the certificate number only. Mention the standard in the description if you want shoppers to see it.
Where does the MADE IN GREEN product ID go?
In the separate OEKO-TEX Institution field. This field is for the certification number.
