    Step-by-step

    1. 1

      Find the DBD on the paperwork

      The DBD normally appears on invoices, contracts, the website footer or official correspondence. It is the number counterparties are required to quote.

    2. 2

      Search the DBD

      Enter the number exactly as printed. Punctuation and spacing vary between documents — strip them if the search returns nothing.
