has anyone tried just entering some random numbers? i cant remember mine being checked?
- The first seven digits of the VAT registration number are listed vertically.
- Each digit is multiplied by a number, starting with 8 and decreasing to 2.
- The sum of the multiplications is calculated.
- 97 is subtracted from the sum as many times as is necessary to arrive at a negative number.
- The negative number should be the same as the last 2 digits of the VAT registration number if it is valid.
Example
VAT registration number 339 0727 47
3 *8 = 24VAT registration number 339 0727 47
3 *7 = 21
9 *6 = 54
0 *5 = 0
7 *4 = 28
2 *3 = 6
7 *2 = 14
Total = 147
147 - 97 = 50 - 97 = - 47
As the negative number(- 47) is the same as the last two digits of the VAT number, the number is valid.
147 - 97 = 50 - 97 = - 47
As the negative number(- 47) is the same as the last two digits of the VAT number, the number is valid.
Be careful playing with VAT numbers - you could be committing fraud
