Types:

0
Some combination of letters and digits, the list below will explain exactly what.
1
Two letters followed by two groups of two digits.
Originally the only letters in normal use where A, B, D, E, F, G, H, J, K, L, N, P, R, S, T, U, V, X and Z. Later also M was used, and others but not for vehicles.
This type started in 1951 with letter N as first letter and for each of the normal vehicles, goods vehicles and motorcycles six second letters, alternating in alphabetical order. Wide goods vehicles got a single second letter (B). When Z was exhausted as first letter the sequence would continue with A as first letter. After J followed (for the first time) M. When this was exhausted (for normal vehicles, the other classes had not reached the letter A as first letter), the issue started with MZ going backwards going over all unused combinations (except those with B as second letter) to EA. Goods vehicles and wide goods vehicles were joined in a single class in 1968, issue continued with the (originally) small goods vehicles series and when first letter D was exhausted with the remaining series with second letter B. Motorcycles just continued until first letter Z was exhausted.
1a
One letter followed by two groups of two digits.
2
Two groups of two digits followed by one letter.
This type was started in 1965.
The letters used where the same as for type 1.
All combinations, except those with second letter B were used for normal motorvehicles. The remainder was used for goods vehicles.
2a
Two groups of two digits followed by a single letter.
3
Two digits followed by two letters followed by two digits.
This type was started in 1973.
The letters used where the same as for type 1.
The use was similar to that of type 2.
3a
Two digits followed by a single letter followed by two digits.

4
Two letters followed by two digits followed by two letters, the first group of two letters is significant.
This type was started in 1978.
The vowels were removed for normal use but the letter Y was added. Also the letter M was only used as first letter in the first group for motorcycles.
Normal and goods vehicles were distinguished by the first letter, B and V for goods vehicles.
The combinations KL, SA and SD are not used in either position.

5
Two groups of two letters followed by two digits, the first group of two letters is significant.
This type was started in 1991.
The same letters as for type 4 were used in the same way, except for the letters K and Y, they are no longer used. Also this time goods vehicles were distinguished by weight, B for vehicles heavier than 3500 kg, V for vehicles lighter than that.

6
Two digits followed by two groups of two letters, the first group of two letters is significant.
This type was started in 1998.
After type 5, the letter K came back in use again, but at first only in the second group, from FK it came back in full glory. For light goods vehicles that letter came only back with the combination VL, these vehicles started much earlier with type 6 than the standard vehicles.

Colours:

Unless otherwise noted plates are dark blue with white digits or reflective yellow with black digits. Before 1977 all plates were dark blue, after that time yellow except in some special cases where blue was still allowed, but now a lighter variant.
Starting 1 February 2000 a blue ribbon has been added to the left like most EU coutries. Also lettering has sligthly changed to prevent fraud. Moreover, when a license plate is lost it is no longer possible to obtain a duplicate. Duplicates have to be made specially and are marked as such. Also trailers no longer carry the license of the towing vehicle on a yellow plate, but on a white plate with black lettering (only two plates are made for each license). Since 1 June 2000 taxi's carry reflective blue plates with black lettering.

Order of issue:

The lists below indicate the letter combination approximately in order of issue, but in some cases out of order issues did occur. For instance, the combinations of type 2 for standard vehicles indicated as reserved but not yet seen, are indeed such. For a long time when papers where lost a new registration was issued rather than new papers for the old registration, and in those cases the new registration would be of the same type as the old registration. So while I have not yet seen these combinations, at least some of them have been issued but at a later date than later combinations.

Used:

Note: I have seen the combinations shown in bold, those in normal type I have either not yet seen or they are not yet issued.

trailers
This is registration only, although you can see them on some plates. In the first place for some time trailers had a diamond shaped plate with in white on red four groups of two symbols. The first three groups formed the registration, the last group indicated the loading limit. Lately I have seen registrations like this on trailers in black on yellow instead of the registration of the towing truck as it was before.

While I have seen these registrations painted on cardboard I have also seen them on true plates, black on white.
type 0:
The registration consists of two groups of three symbols separated by a dash, black on white. The first symbol is always a digit, the next two are always letters, the remaining symbols are either digits or letters. (Note that due to some quirk in the mind of a civil servant the letter Q is before P.)
Position 2 to 4 indicate the day of registration as follows:

Truly one of the most bizarre encodings I ever encountered.

Special plates

1966 saw the introduction of special plates for vehicles that were allowed to drive tax free on the road only one day a year. The registration consists of a first line with a single digit and a second line with one letter and two digits. Apparently only about 100 such registrations have been issued.
In 1971 new plates for caravans were introduced as shown here. The first line consists of two letters for the province and two digits for the year of registration, the second line is a serial number. The provinces are coded as follows:
DRDrenthe
FRFriesland
GLGelderland
GRGroningen
LBLimburg
NBNoord Brabant
NHNoord Holland
OVOverijssel
UTUtrecht
ZHZuid Holland
ZLZeeland
I do not know whether Flevoland has received a separate code when it became a province in 1986.


The so-called "FINO" plates are diamond shaped with white symbols on red. They are used for trailers. The symbols are divided in a top line of two symbols, a middle line of two groups of two symbols, separated by a hyphen, and a bottom line of two symbols. The top line and middle line form the registration of the trailer (see above), the bottom line gives an indication of the maximum weight of the trailer as follows:

If the maximum weight is (rounded to a multiple of 100 kg) less than 10.000 kg the bottom line consists of two digits indicating the weight in 100 kg units (again rounded). If the maximum weight is between 10.000 kg and 32.000 kg the line consists of a letter (indicating a multiple of 10 from 100 to 310) and a digit for the units. If the maximum weight is above 31.950 kg the bottom line consists of the letters XX.
The single letter indicated above translates as follows:
A100
B110
C120
D130
E140
F150
G160
H170
J180

Vehicles for the transportation of animals got in 1985 new plates that had to be carried in addition to the standard plates they did already carry. The first line contains the area in square meters. The second line contains the vehicle registration if it is self-propelled, the trailer registration if it is a trailer above 750 kg and the chassisnumber (as shown here) when a trailer lighter than that. The third line has year and month of registration and a serial number. Finally, the number on the last line indicates the kind of animals.
