Where dispute and fraud forms go at Frost Bank

A wire transfer authorization to Frost Bank goes to the wire transfer desk, which keeps its own line. Name the department on the cover sheet so a same-day request is not misrouted. A brief call to Frost Bank ahead of a wire deadline helps staff watch for the fax.

Finding the right department to fax at Frost Bank
