UIC wagon numbers

Wagon numbers (or coach numbers) are key data for railway operations. The wagon number enables a railway wagon or coach to be positively identified and forms a common language between railway operators, infrastructure companies and the responsible state authorities. The system of wagon numbering described below has been laid down by the International Union of Railways (Union internationale des chemins de fer or UIC) and is used in a similar way to that used for the locomotives and multiple units.

The complete wagon number comprises 12 digits. The individual digits within the number have the following meaning:

First and second position: Interoperability code (on multiple units Type code)
Third and fourth position: Owner's code (since 2006: UIC country code)
Fifth to eight position: Type number
Ninth to eleventh position: Serial number
Twelfth position: Self-check digit

Calculation of the control digit

The digits of the wagon number are multiplied individually from left to right alternately by 2 and 1. Then the sum of the digits is produced. The difference between this sum and the next multiple of ten is the control or check digit. This control number is placed after the eleventh digit of the main number separated by a dash.

Examples

Wagon number: 21-81-2471217

2 1 – 8 1 – 2 4  7 1 2 1  7
    multiplying by 
2 1   2 1   2 1  2 1 2 1  2
          gives
4 1  16 1   4 4 14 1 4 1 14   sum = 37, next multiple of ten = 40 => Control digit = 3

Wagon number: 51-80-0843001

 5  1  8 0 0 8 4 3 0 0 1
    multiplying by 
 2  1  2 1 2 1 2 1 2 1 2
          gives
10  1 16 0 0 8 8 3 0 0 2      sum=30, next multiple of ten = 30 => control digit = 0

Country code

At the beginning of 2006 the coding of wagon numbers was changed. Previously these indicated the owner (almost exclusively these were state railways), from then on the number became a country code. The owner is indicated by a subsequent letter code. For a vehicle registered in Germany by the AAE, which previously had its own code as one of the few private railways, the code became, for example, "68 AAE" "80 D-AAE". (see also UIC country code)

Reading of numbers

Since numbering systems began, the wagon number has been read visually; that is still the method of choice today (2008). No railway company is able to read the wagon number automatically with the required reliability (less than 1 error in 10,000). Using OCR readers the numbering (DB AG: Font Gerade Normschrift DIN 16 Variant DB) can be only be read to an accuracy of no better than 5% (1 in 20).

Numbering systems

The UIC has agreed the following numbering systems, details of which are given in their leaflets:

These agreements have not yet achieved the status of a standard or norm.
