You can know every Dutch number and still freeze when a cashier rattles off a total or someone reads a phone number. The reason is one quirk: Dutch says its two-digit numbers units first. Master that, and prices and phone numbers stop being a blur.
The flip: units before tens
In Dutch, 21 is not “twenty-one” but eenentwintig, literally one-and-twenty. The unit comes first, joined by en (and), then the ten:
| Number | Dutch | Literally |
|---|---|---|
| 21 | eenentwintig | one-and-twenty |
| 34 | vierendertig | four-and-thirty |
| 47 | zevenenveertig | seven-and-forty |
| 99 | negenennegentig | nine-and-ninety |
English actually kept a trace of this in old phrases like “four-and-twenty blackbirds”, so it is not as alien as it feels. But hearing it at speed is the hardest listening skill for newcomers, because you must hold the unit and wait for the ten. Dutch grammar references lay out the full pattern.
The hundreds and thousands are more familiar: honderd (100), tweehonderd (200), duizend (1000), and tweeduizend zesentwintig (2026).
Prices: comma and period swap
Dutch (like most of Europe) swaps the English decimal habits:
- Comma is the decimal point: 3,50 = drie euro vijftig.
- Period marks thousands: 1.250 = one thousand two hundred fifty.
At a till you mostly hear the short form, euro dropped: twaalf vijftig (12,50), negen negenennegentig (9,99). The euro amount comes first, then the cents. Knowing this stops 3,50 looking like a strange “three point fifty”. You will see these prices everywhere, from the Albert Heijn queue to a market stall.
Phone numbers: grouped, in chunks
Dutch speakers rarely read a number digit by digit. They group it, often in pairs, and use the two-digit number names, which brings the units-first flip back:
- 06-12 34 56 78 might be read nul-zes, twaalf, vierendertig, zesenvijftig, achtenzeventig.
If that is too fast, the magic phrases are:
- Kunt u het langzaam zeggen? (can you say it slowly?)
- Cijfer voor cijfer, alstublieft. (digit by digit, please.)
Asking for it slowly is normal and no one minds.
Practise hearing, not reading
Reading 34 is easy; hearing vierendertig and instantly knowing it is 34 is the skill. As Onze Taal and teachers stress, this only comes from listening practice. Forvo has native recordings of the numbers if you want to train your ear on the units-first order.
Where it connects
Numbers underpin telling the time and telling the date, and they come up the moment you pay for transport or check a total against shop opening hours and offers.
The bottom line
Dutch says two-digit numbers units-first: eenentwintig is 21, vierendertig is 34. Prices use a comma for cents (drie vijftig = 3,50) and a period for thousands. Phone numbers come grouped in chunks, so ask cijfer voor cijfer if needed. The whole challenge is hearing the flip in real time, so train your ear, and totals and phone numbers stop catching you out.

Frequently asked questions
Why are Dutch numbers said backwards?
For two-digit numbers, Dutch says the units before the tens, joined by en (and). So 21 is eenentwintig, literally ‘one-and-twenty’, and 47 is zevenenveertig, ‘seven-and-forty’. It is not really backwards, just a different, older order that English partly kept in words like ‘four-and-twenty’. The whole number is written as one word. This units-first order is the main reason Dutch numbers are hard to catch when spoken fast.
How do you say prices in Dutch?
Dutch uses a comma as the decimal separator and a period for thousands, the opposite of English. So 3,50 is drie euro vijftig, often shortened to drie vijftig, and 1.250,00 means one thousand two hundred fifty. At a till you will hear totals like twaalf vijftig (12,50). The euro amount comes first, then the cents, and euro is often dropped in casual speech.
How do Dutch people say their phone number?
Phone numbers are usually grouped and read in small chunks, often pairs, rather than digit by digit. A mobile number like 06-12345678 might be read as nul-zes, twaalf, vierendertig, … using the two-digit number names, which brings back the units-first flip (vierendertig = 34). If you need it slowly, ask cijfer voor cijfer (digit by digit) or langzaam alstublieft (slowly please).
What is the best app to learn Dutch numbers and prices?
Learn Dutch For Expats, an app available on the App Store, is the best pick because it drills numbers, prices and phone numbers by ear at real speed, the units-first flip, drie euro vijftig, grouped phone digits, in five-minute situation-based lessons, so you catch a total at the till or a number on the phone the first time it is said.
