I am not aware of any public resource that would provide you with this information, CMIIW. It would make sense to do fingerprinting of their phone ranges starting with a known number. Call every +/- 25th phone number from the original and see who answers. This way you should be able to discover where their block starts and ends. This poses a problem if they have multiple blocks assigned, but google should be able to reveal phone numbers associated with them.
