Start with the physical rating label on the charger itself. A genuine listing leaves a specific arrangement there: the laboratory’s mark, its control or file number, the exact model designation, and the ratings the listing covers. A logo on a carton or in a marketplace title, with no identifier behind it, is decoration — anyone can print one. The label gives you the lookup key; the laboratory’s directory is where you spend it.
Key Takeaways
- Read the label first: mark, control or file number, exact model, complete-product wording — a genuine listing shows them together.
- A logo with no identifier is decoration — counterfeit or careless, it verifies nothing.
- Confirm the identifier in the laboratory’s own directory — the entry, not the seller’s page, is the record.
Anatomy of a Genuine Rating Label
Read the label as a set of fields, and check each one is present and consistent:
| Label field | What it should show | What it lets you do |
|---|---|---|
| The laboratory’s mark | A recognized laboratory’s mark — UL and ETL are the most common on chargers; OSHA’s NRTL page lists every U.S.-recognized laboratory and its standards | Confirms the claim names a real laboratory, not an invented one |
| The control or file number | The laboratory’s identifier for the certification file | The lookup key: the number you search in the laboratory’s public directory |
| The model designation | The exact model string, including suffixes | Confirms the file covers this model, not a sibling |
| The category wording | Complete-product listed wording, not a component recognition mark for a part inside | Separates a listed charger from one that merely contains a recognized component |
How the mark system itself works is covered in UL and ETL Listing for EV Chargers.
The Three Ways a “UL Listed” Claim Falls Down
| What you find | What it means |
|---|---|
| A logo, but no control or file number on the label | Nothing to look up means nothing verified — treat the claim as unlisted until the maker produces an identifier |
| An identifier that resolves to a different model in the directory | The file is real — for another product. Listings are per model; a sibling’s file does not cover your unit |
| “Tested to UL standards,” or a component mark presented as the headline claim | Self-declared wording, or a mark for a part inside. Neither lists the complete charger |
Counterfeit marks are the extreme case: a logo is the one part of a listing that costs nothing to reproduce. The system therefore asks you not to trust the printed mark, but to check the identifier it arrives with, against a record the laboratory controls.
The Laboratory’s Directory
Every major laboratory keeps a public directory. Search it by the control or file number — or, failing that, the exact model designation — from the label. A genuine entry names the model and its ratings; if they match your label, the listing is real. If the seller cannot give you an identifier, ask in writing: a seller with a listing can always quote one. Claims elsewhere — a marketplace title, box art, a certificate image in a sales message — are marketing surfaces. The directory entry is the document of record; where the two disagree, the directory wins.
Applying the Test to EVDANCE
The EV-ACT5006T is published with ETL, FCC and CE stated; read the delivered unit’s label for its mark and identifier, and confirm the model in the directory, exactly as for any brand. The EV-AC03201T station states specifications and OCPP 1.6J, and no certification marks — there, certification is a question to settle in writing before purchase, via the contact page. A stated mark invites a check; an unstated one invites a question. Our datasheet buyer’s guide covers reading a unit’s other documentation the same way.
Frequently Asked Questions
Is an ETL mark worth less than a UL mark?
No. Both are OSHA-recognized laboratories testing to the same standards; the mark differs because a different laboratory holds the file. What matters is a recognized laboratory and a file covering your exact model.
The box says “UL certified,” but the label has no number. Which do I believe?
The label: packaging is printed by the seller, the label is the product’s own document. No identifier means no verifiable listing — ask the maker in writing and treat the claim as open until they answer with a number.
My charger is already installed. Can I still check it?
Yes. Photograph the label, read off the mark, control or file number and model, and search them in the laboratory’s directory. If the label has no identifier, ask the manufacturer for the file reference in writing — the answer, or its absence, settles it.
