Common questions

Which carriers support excess liability coverage?

6 carriers publish a code for excess liability coverage, and a further 1 support it through a request field rather than a code. Declared value above the carrier's standard released-value limit.

Is there a standard excess liability coverage code across carriers?

No. Each carrier defines its own code, so the same service is spelled differently at every carrier you integrate with — ABF Freight uses Acc_ELC, Banyan Technology uses DL, Daylight Transport uses Excess Liability, RoadRunner uses ECC. A code is only meaningful together with the carrier it belongs to.
