BR-DE-27 Telephone number too short

The seller's telephone number (BT-42) should contain at least three digits, or the validator warns.

The rule's official text

In BT-42 sollen mindestens drei Ziffern enthalten sein.

The seller's telephone number (BT-42) should contain at least three digits.

What usually causes it

  • The field holds a placeholder such as - or n/a.
  • It holds text such as "see website" instead of a number.

How to fix it

  1. Enter a real telephone number, ideally in international format, such as +49 30 1234567.
  2. The field is mandatory in XRechnung (BR-DE-6). Leave it empty and the warning becomes an error.
