Regular expressions for registant data[Link]
DNS Belgium uses the following regular expressions to validate registrant data.
This overview is also available as a csv file or a json file.
VAT numbers[Link]
VAT is mandatory for organisations. It is allowed to use ‘PENDING’ for VAT if applicable
If entered, VAT must be the correct syntax for the countrycode of the registrant
For VAT numbers, we use the regular expressions by O’Reilly.
Postal codes and phone numbers[Link]
Postal code must have the correct syntax for the countrycode of the registrant. For a country without postal codes, we allow ‘0000’ or ‘00000’
Length of phone number must be correct for the phone prefix
These are the regular expressions used:
