What is european union labor number?

A SCAM I'm afraid..

Yup, complete scam. Don't pay them the $30 they're asking for and don't be fooled by the 'deadline'. The number doesn't exist in Europe and hence there is no deadline. The only deadline is the one that determines when your money disappears in their pockets. See our blog: http://blog.eurojobs.com/2012/02/european-labour-department-number/
