Netherlands

Nederland

Dutch registrations are national and normally stay with the vehicle. The character pattern changes over time in numbered ‘sidecodes’, making the broad era easy to estimate.

CURRENT STANDARD

Variable sidecodeIntroduced 1951 · sidecode 11 for cars since 2024

THE SYSTEM

How the numbering works

A sidecode defines the arrangement of letters and digits rather than a fixed permanent format.

New sidecodes are introduced as combination pools run out, so the layout gives a broad age clue.

Letter ranges also distinguish vehicle classes: B for heavy commercial vehicles, V for light vans, W for trailers and L/T for agricultural vehicles.

Modern serials omit vowels plus C and Q; M and W are generally avoided as serial letters because of their width.

The registration stays with the vehicle and may eventually be reused after a quarantine period.

BEYOND THE STANDARD

Special & distinctive series

Colour and suffixes can completely change a plate's meaning.

Standard sidecode 11

Passenger cars entered the AAA-00-A arrangement in June 2024.

Taxi

Licensed taxis use black characters on a light blue plate.

Trade

Green dealer plates may move between stock vehicles for authorised test and transfer journeys.

Historic

Qualifying pre-1978 vehicles may display white characters on period dark blue.

Motorcycle

Motorcycles use a compact two-line yellow GAIK plate with an M-led series.

Fast moped

45 km/h mopeds carry yellow plates; slower 25 km/h snorfietsen traditionally use light blue.

Light trailer

Trailers up to 750 kg and carrier boards repeat the towing vehicle’s registration on white.

Export / transit

Export and transit plates use white fields and time-limited documentation.

ARCHIVE FORMATS

How Netherlands's plates evolved

6 reconstructed milestones show how colour, geography and numbering changed before the present system.

1898–1906

First national numbers

The Netherlands became an early national registration pioneer; the first plates were simple numbers.

1906–1951

Provincial blue plates

A province prefix and keeper-bound serial preceded the central RDW system.

1951–1965

Sidecode 1

National vehicle-bound registrations begin as XX-00-00 on dark blue.

1965–1973

Sidecode 2

The letters move behind two numeric groups while the dark-blue field remains.

1973–1978

Sidecode 3 and colour transition

Letters move to the centre; light blue and optional reflective yellow bridge the colour change.

1978–2000

Yellow before GAIK

Reflective yellow becomes standard while sidecodes continue changing as pools fill.

1898

Plate number 1

The Netherlands becomes one of the earliest countries to register motor vehicles.

1906

Provincial system

Letter prefixes identify provinces and registrations follow the owner.

1951

National sidecodes

Registrations become vehicle-bound and new layouts are introduced sequentially.

1965

Sidecode 2

Two numeric groups move before the two letters.

1973

Sidecode 3

The letter pair moves between two groups of digits.

1978

Yellow required

Black on reflective yellow becomes the national standard.

2000

GAIK control

Controlled manufacture and issue bring the modern EU-band plate.

2008

Three-letter blocks

Sidecode 7 expands private-car combinations.

2014

Credit-card document

The registration certificate moves from paper to a chip-equipped plastic card.

2021

Agriculture and tractors

Road-going agricultural vehicles enter national registration with L and T families.

2024

Sidecode 11 for cars

AAA-01-A begins serving passenger cars after earlier vehicle classes.

2025

Special e-step registration

Approved special mopeds, including eligible electric steps, begin using an E-led sidecode 12 series.

BEYOND THE EVERYDAY

More plates worth knowing

Special status, vehicle class or use can change the colour, prefix, suffix or even the entire registration logic.

Taxi

Licensed taxis use black characters on light blue.

Trade

Green dealer plates can move between stock vehicles for permitted journeys.

Historic

Qualifying pre-1978 vehicles may display dark blue plates with light characters.

Duplicate mark

A small counter above a dash records how many replacement sets have been issued.

Light trailer

White repeater plates copy the towing vehicle’s registration.

Diplomatic CD

The CD series identifies diplomatic vehicles.

Motorcycle

M-led registrations appear on a compact two-line yellow plate.

Fast moped

A 45 km/h bromfiets uses yellow; slower snorfietsen traditionally use light blue.

Export / transit

White time-limited plates serve export or onward transit rather than permanent registration.

Royal household

AA registrations are reserved for the Royal House; defence and diplomatic fleets have other protected groups.

FOURTEEN SIDECODES

The layout is a chronological clue

A sidecode changes the position and size of the three groups; it is not a regional identifier.

1 · 1951AA-00-00

The first national vehicle-bound arrangement, still used for some imported oldtimers.

4 · 1978AA-00-AA

The first standard black-on-yellow national layout.

6 · 199900-AA-AA

The final pre-three-letter passenger-car pattern.

7 · 2008 cars00-AAA-0

Passenger cars gain the first three-letter group.

10 · 2019 carsA-000-AA

A single letter leads three digits and two letters.

11 · 2024 carsAAA-00-A

The current passenger-car pool began with GBB-01-B.

CATEGORY LETTERS

Some starting letters identify vehicle class

The exact rule depends on sidecode, but several leading letters are deliberately recognisable.

MotorcycleM

M-led series serve motorcycles across several sidecodes.

CommercialB / V

B is associated with heavier commercial vehicles and V with lighter vans.

TrailerW

Trailers above 750 kg use their own registration; lighter trailers repeat the towing mark.

Semi-trailerO

O-led registrations serve opleggers.

Agriculture / tractorL / T

National registration began for these road-going classes in 2021.

MopedsD / F / E

D and F serve mopeds; E was introduced for approved special mopeds in 2025.

COLOUR & SECURITY

GAIK colour identifies use

Controlled manufacture, a punched production code and replacement counters help tie the physical plate to its record.

OrdinaryBlack on yellow

Cars, motorcycles, commercial vehicles and heavy trailers use yellow GAIK plates.

TaxiBlack on light blue

Mandatory for qualifying passenger transport since 2000.

TradeBlack on light green

Transferable handelaarskentekens are limited to authorised business use.

HistoricLight on dark blue

Period plates remain possible for qualifying vehicles first registered before 1978.

Repeater / exportBlack on white

White is used for light-trailer repeaters and time-limited export or transit plates.

Replacement counterSmall digit

A duplicate code records how many replacement plate sets have been issued.

PHYSICAL MODELS

Dutch plates are not one shape scaled down

The vehicle and its approved mounting space determine whether the registration is long, stacked or a dedicated small format.

Standard long520 × 110 mm

The usual yellow car, commercial-vehicle and heavy-trailer plate.

Standard two-line340 × 210 mm

A stacked yellow alternative, common on vans and other suitable recesses.

American model 18.2310 × 110 mm

Allowed only when the registration record specifically authorises the small non-EU format.

Motorcycle210 × 143 mm

A dedicated two-line yellow plate with the NL field.

Moped long445 × 105 mm

Yellow for 45 km/h or blue for 25 km/h, with no NL field.

Moped two-line340 × 240 mm

The larger portrait alternative also has no integrated international identifier.

SIDECODES & OLD PROVINCES

Fourteen layouts, one national sequence

GOOD TO KNOW

Three road-side clues

Registrations generally follow the vehicle, not its keeper.

The Netherlands was an early European adopter of reflective yellow plates.

Motorcycles and mopeds use their own sidecode series.
