EFFF – this is the strongest policy & transactions will only pass if both address numeric & post code checks have passed. Partial matches are treated as failures

EPFP – this policy means that transactions will only pass if both the address numeric & post code checks have passed, but if the results of both are unknown, and then pass the transaction. Partial address numeric results are treated as passes, but partial post code checks are treated as failures BPPF – this policy means that the transaction will fail only if both the address numeric and post code checks have failed, but if the results of both are unknown, then fail the transaction. Both address numeric and post code partial results are treated as passes

NPPF – this policy means that the transaction will pass even if the results of the address numeric and post code checks are failed, but if the results are unknown, and then fail the transaction (not a recommended policy!). Both address numeric and post code partial results are treated as passes NPPP – this is the weakest policy & transactions will pass regardless of the results of the address numeric & post code checks. Both address numeric and post code partial results are treated as passes.
