Whats the difference between NUR and NRCV status codes?
• NUR generally means that the number is not routable and is likely to be of an incorrect format or invalid number. The number needs to be confirmed as being of valid format and could be tried again but is likely to fail again unless it is changed. • NRCV indicates that a (most likely) temporary delivery issue has occurred within the carrier network and that it could be tried again. A retry is recommended after a short delay and may work even without changes in the number submitted.
