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

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

Digits 1-2: Type of vehicle and indication of the interoperability capacity
(on multiple units, type)
Digits 3-4: Country Code (Owner before 2006)
Digits 5-8: Vehicle type information
Digits 9-11: Individual running number (serial number)
Digit 12: Self-check digit

Calculation of the self-check digit

The digits are multiplied individually from right to left alternately by 2 and 1, and digit summed using the Luhn algorithm. The difference between this sum and the next multiple of ten is the check digit, placed after the eleventh digit, 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 => check 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 => check digit = 0

Country code

At the beginning of 2006 the country replaced the owner (almost exclusively state railways), with the owner now indicated by following letters. For example, for a vehicle registered in Germany on the AAE, which had its own code as a private railway, "68 AAE" became "80 D-AAE". (see also UIC country code)

Reading of numbers

Numbers are read visually, the method of choice today (2008). No railway is able to read the 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 the following numbering systems, as detailed in leaflets:
