TCR collects information on the company and messages that are being sent, they then vet this information to help the carriers determine how they will handle your messages. The vetting process is based on several things, with legitimacy of business being one of the most influential...does the EIN exist, does it match the company name, etc. Once TCR determines the reputation, this information is shared with the carriers by brand and campaign IDs. Each carrier uses the information for throughput and speed of sending their messages.
