What does the E mark mean?

Helmets, child seats, tyres, headlamps, glass and seat belts all carry an approval mark: a letter, a number, and a longer number beside it. This reads the European one, from the regulation in force.

The number is not where the thing was made. It is the country whose authority granted the approval, which is a different question and usually a different answer.

There are two marks, and almost everyone calls both of them the E mark

They use the same country numbering, which is exactly why the confusion survives. They are not the same approval and they are not granted under the same instrument. The act draws the line itself — where a UN Regulation calls for a circle:

“a rectangle rather than a circle shall be used … Instead of the upper-case letter ‘E’, the lower-case letter ‘e’ shall be used”

And Annex V defines the EU mark itself in the same terms — “A rectangle surrounding the lower-case letter ‘e’, followed by the distinguishing number of the Member State which has granted the type-approval”.

So the shape around the letter is the whole distinction, and it is the one thing nobody looks at. This page reads the EU number. It cannot read a UN approval, because this act does not define one — it only says what the EU does instead.

The country numbers

28 member states, from Annex IV. The same list appears again in Annex V for the mark stamped on a component, and the two agree.

The numbers are not consecutive. 10, 14, 15, 16, 22, 28, 30, 31, 33, 35, 37, 38 and others were never allocated, so a gap is not a mistake in the number you are reading — and a number in a gap may well be a UN approval, whose country list runs well beyond the EU and is not in this act.

Two things about this list worth saying plainly

The United Kingdom is still in it. e11 is the United Kingdom in an act made in 2020, and approvals issued under it are still on parts in circulation. This page reports what the act says rather than what the reader may expect it to say now.

And this is not the list most search results will show you. Directive 2007/46/EC carries the same table, is what most pages cite, and is repealed. Its list has 27 entries; this one has 28, because Croatia (e25) was added. Building on the familiar document would have given a table wrong about exactly one country and right about everything else, which is the hardest kind of wrong to notice.

How the number is put together

The sections are “separated by an asterisk”, and how many there are tells you what was approved:

The act states the first two counts outright. Three-section numbers are not given a count in the same sentence; they are what its individual-vehicle examples look like, and this page says so in those words rather than claiming the act defines it.

Four sets of letters that replace the regulation number

The act works its own examples

All 11 of them, each with a sentence naming the country that granted it. Every one is a test in check-emark.js: the decoder has to reproduce the act’s own reading of its own examples, not a reading of the rules above them.

What the mark does not tell you

Not where it was made. This is the misreading the page exists for. e4 does not mean Dutch: it means a Dutch authority granted the approval. A manufacturer may hold an approval from any member state and build anywhere. The mark follows the approval, not the factory.

And not when. There is no year anywhere in an approval number. The four-digit field counts approvals, not years. If you need the age of a helmet or a child seat, the date is usually moulded into the shell separately — and it is not this number.

That makes this the second tool here that cannot date what it reads, after the railway page. Both say so in every reading rather than in the small print, because a dating site that stays quiet about it is inviting the reader to assume.

A note on where this came from

EUR-Lex states its own terms: “Unless otherwise specified, you can re-use the legal documents published in EUR-Lex for commercial or non-commercial purposes”, under Commission Decision 2011/833/EU. So the tables above are complete rather than summarised.
