Can anyone help me find a source of the RAO (regional accounting office) codes for all NPA-NXXs? Bellcore provides it at a price which we can't handle. This seems like data which would be public domain. The codes are used to determine which "billing office" gets a credit card charged call. Carl Wright | Lynn-Arthur Associates, Inc.
