Specifies the URL of the EU web service that is used by default to verify Tax registration numbers.

Warning
This web service uses the http protocol, which means that data transferred through the service is not encrypted.

Note
You may experience downtime for this service for which Microsoft is not responsible, as the service is part of a broad EU network of national Tax registers.

You can use an EU web service to verify that Tax registration numbers that you enter on customer, vendor, or contact cards are valid. When you modify the Tax Registration No. field on a card where the value in the Country/Region Code field is an EU country/region, then the new Tax registration number and your user ID are logged in the Tax Registration Log window. To verify a Tax registration number, you can choose the DrillDown button next to the Tax Registration No. field to open the Tax Registration Log window and then start the verification function. For more information, see How to: Verify Tax Registration Numbers.
