How to check a supplier's FCC, UL or CE claim yourself, for free in detail
Answer
All three can be checked free in official sources. FCC: only products with a radio function carry an FCC ID (most non-radio products use SDoC self-declaration and have none); search the FCC ID on the product or label in the FCC ID Search; the grantee should match the supplier or its brand. UL: search the file number or company in
UL Product iQ (free account). CE: there is no central
EU certificate; the manufacturer signs an EU Declaration of Conformity. Where a notified body is required, its 4-digit number sits next to the CE mark and can be checked in the EU notified-bodies database.
- Applies to
- Buyers importing electronics, chargers, toys and other regulated products from China into the US or EU.
Dear friend,
Welcome! This letter sets out what you need to know, plainly and in order.
Quick checks
| Mark | Where to check | What should match | Source |
|---|---|---|---|
| FCC ID | Grantee code (first 3 or 5 characters) and product code; grantee name, product type and photos | ||
| UL | File number, company name and product category | UL | |
| CE | Ask for the EU Declaration of Conformity | Manufacturer name and address, product model, harmonised standards, signature and date | |
| CE with notified body | EU notified bodies (NANDO) | The 4-digit number exists and covers this product type | European Commission |
Red flags (signals, not proof)
- A "certificate" for CE from a body that is not a notified body. The EU says such voluntary certificates are not legally recognised and can mislead buyers.
- The FCC grantee is a different company, and the supplier cannot explain the link (for example, a module maker).
- The supplier refuses to share the Declaration of Conformity or test report.
- A product that does not need CE (no EU rule covers it) still carries CE: the EU says CE must not be used then.
Still uncertain
- UL Product iQ requires a free account; some listings are limited.
