-**Verified:** Verified numbers have gone through the toll-free verification process and have been approved. Their traffic is subjected to limited filters. If traffic does trigger any filters, that specific content is blocked but the number is not automatically blocked.
162
-
-**Pending**: Numbers in a submitted application get into pending state 2-3 days after application is submitted. Numbers in pending state have an associated toll-free verification form being reviewed by the toll-free messaging aggregator. They can send at a lower throughput than verified numbers, but higher than unverified numbers. Blocking can be applied to individual content, URLs, or there can be an automatic block of all traffic from the number. These numbers remain in this pending state until a decision has been made on verification status.
163
-
-**Unverified:** Unverified numbers have either 1) not submitted a verification application or 2) have had their application denied. These numbers are subject to the highest amount of filtering, and numbers in this state automatically get shut off if any spam or unwanted traffic is detected.

+
-**Unverified:** Unverified numbers have either 1) not submitted a verification application, 2) have submitted the verification application and are waiting for a decision, or 3) have had their application denied. These numbers will not be able to send any SMS traffic.
