Hello,
 
It is not possible to add 6-digits LC codes to your website. Please update this as there are now labels with a 6-digit one, and the maximum is currently 5.

This is a schema change because the maximum value of a label code is currently hardcoded in a constraint added when declaring the label table (name is assigned by psql but seems to be label_label_code_check). We will drop the autogenerated label_label_code_check and add a label_code_length constraint that we have more control over and will not be present in mirror servers, so that future changes, if needed, do not require the same amount of waiting.
