Regular expressions for registant data[Link]
DNS Belgium will use the following regular expressions to validate registrant data.
The table can be downloaded in csv or json format from the DNS Belgium github repo.
VAT numbers[Link]
VAT is mandatory for organisations in EU/EAA. It is allowed to use ‘PENDING’ for VAT if applicable
Contacts with VAT value PENDING will be checked after 3 months. If there is no valid VAT number, they will receive a warning and may be subjected to the Revoke procedure
If entered, VAT must be the correct syntax for the countrycode of the registrant (see table below)
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:
