Bulk VAT Number Validation

Get Started

Simple and efficient process...

Bulk VAT Validator uses regular expression matches to check if a vat number is formatted correctly for a given country, if the format looks good it then performs a check against the official European Commission VIES database to check the validity of the number. The user interface is very easy to use and we've made the process very simple so administrative staff can easily use the service.

VAT Numbers should be externally verified whenever you do business with a VAT registered customer or supplier, preferably before being entered into any accounting system. It is also recommended to perform additional checks on a regular basis, e.g. once per quarter.

Step 1 Upload a CSV file

Choose between a 1 or 2 column CSV file to upload. If your VAT numbers have the required country prefix for example; a typical UK VAT number would be in the format GB289111588 you can upload a 1 column CSV. If the country prefix is held in a different column you can upload a 2 column CSV. There is also an option to set a default country prefix which is used if a prefix isn't found for a particular number.

Step 2 Wait for processing

Processing time very much depends on how many numbers are to be validated at any one time across our service, the service runs continuously in the background, so once you've uploaded your CSV file you can leave it and come back to it later.

Step 3 Download PDF or CSV

Once each batch is processed you then have the option of downloading a PDF report or a CSV file showing the validity of the numbers and the associated company data returned from the VIES service if a VAT number is found to be valid.

Customer Feedback

"Glad I used your website services for VAT checking as we used to spend days to check the validity of VAT numbers one by one. This has significantly reduced our work load and most importantly the time we spend. The PDF report has all the info whatever HMRC needs and happy to use this every month moving forward."
