When I applied for a number under the 'free' option, D&B said they would to contact the company. However, they would never leave a voicemail - the 'accounting' IVR option goes straight VM because it's not a full time position. When I called them I was told I need some ~$700/yr service if I wanted to initiate the process on that phone call (though it was strongly recommend that I go with $1500/yr option). Some time later, using their business search function, I found that they had issued a number for my company.
