# VAT Number Checking?

M

#### Mark

As a trainee in practice years ago I used to know a method of checking
whether a VAT registration number was valid.

It entailed something along the lines of:

Take the first number in the VAT registration and x 9?
Take the second and x 8
Take the thirds and x 7
etc
etc

Then add all the resultant sums to together.

From this number it was continually subtract a figure until the number you
has went negative - and it was this negative two digit number that was the
last two digits of the VAT registration.

I know at the time HMC&E wouldn't confirm that this worked.

Does anyone know what the calculation is please?

Thanks

Multiply first digit of VAT No by 8, then multiply second digit by 7,
etc until multiply 7th digit by 2.

Add up the 7 numbers you've just produced.

Divide by 97 to leave a remainder (obviously less than 97)

Subtract the remainder from 97.

The answer should equal the last two (8th and 9th) digits of VAT
number.

why not just go to this site, enter the EU country and then the vat
number, it'll tell you if it's valid or not

That's a very useful site.

Mind you, it does not tell you (i) if that VAT number belongs to the
entity concerned (i.e. may be someone else's number) or (ii) whether

They will ask you the VAT number of the business that you wish to
check. They will then be able to confirm the name and address of the
customer, or tell you that it is an invalid number
