A Complete Database of US Trucking Carriers
We regularly update the Shipper Shield database to reflect the most comprehensive list of MC and
DOT numbers from government sources. Additionally, we have a special agreement in place that gives
us an up-to-date list of all known SCAC codes. Although our system allows searching by name, the
sheer size of the FMCSA database makes it much more practical to search on MC, DOT or SCAC. You would
be shocked by the number of carriers with the same name across the country. Also, the mergers and acquisitions
of carrier entities have left many large companies having multiple MC numbers and many dormant MC and DOT codes
for companies that are still active under a different number.
