ACH Fraud Prevention

Fraud Protection

City National Bank is committed to providing our clients with the latest security measures available to prevent fraud. Our ACH Fraud Protection Service offers a way to help you protect your business accounts from unauthorized ACH debits and credits. You can customize a solution to meet your needs.

ACH Filter Authorizations with ACH Positive Pay

ACH Filter Authorizations are used to identify what you do want posted to your account. An ACH Filter Authorization lets City National Bank know what items are approved for posting on your account.

You can individually authorize every ACH debit and credit to your account, or opt to preauthorize transactions for trusted companies.

With just a few clicks in our online system, you review all unauthorized ACH items and determine if they should be paid or returned. At the same time, you can quickly add an ACH Filter, so that future items from a trusted company will not need to be decisioned.

ACH Block Orders

ACH Block Orders define what you do not want posted to your account. Return all debits or all credits - or return all ACH items - so they will be blocked from posting and preventing fraudulent ACH transactions.

ACH Block Orders can also be refined and customized to block types of payments or items from a specific payee. For example, ACH Block Orders can be used to:

  • Block all WEB originated payments or all ACH Check Conversions
  • Block all payments from a specific sending company (i.e. ABC Corporation)

Items that meet the criteria of an ACH Block Order are automatically returned to help keep your account secure.
