Web Debit transactions are a key component of the ACH (Automated Clearing House) network, providing consumers with the ability to authorize payments online or through wireless networks. However, this convenience also introduces risk—making data security a top priority. This article outlines the essentials of Web Debit, including who is in scope, requirements, timelines, attestation processes, and best practices for merchants.
What is Web Debit?
Web Debit refers to debit entries that are authorized by a consumer via the Internet or a wireless network. These transactions fall under the Nacha Standard Entry Class Code (SEC Code: WEB) and are specifically for consumer accounts, not commercial ones.
Key Characteristics:
Initiated online or through a wireless network.
Authorized by a consumer (Receiver).
Require stringent security measures to protect sensitive financial data.
Who is in Scope and Who is Exempt?
In-Scope Merchants/Partners:
Those originating WEB debits (card-not-present) with access to consumer data.
Those processing ACH Transaction Types 20 to 26, including Type 26 (Verify Only).
Merchants with ACH allowed = True.
Merchants using a Forte ACH acquiring ODFI such as CMG, COM, F3R, F3RD, MBF, TDB, BMO, WFC, FPB.
Exempt Merchants:
Merchants with only credit card processing (ACH allowed = False).
Gateway-only ACH merchants (pass-through only).
Merchants using only Transaction Type 10 (Credit Card Sale).
Canadian merchants (noted in ISO).
Service/convenience fee-only accounts.
Key Requirements and Timelines
Under Nacha rules, all Originators of WEB debits must complete a security audit annually to ensure consumer financial data is properly safeguarded.
Timelines:
Annual audit required—status resets each calendar year.
Three-month grace period for remediation after a non-compliant audit.
Net new merchants are given one year to achieve compliance.
The Annual Attestation Process
The audit confirms the implementation of appropriate security practices:
Security Categories:
Physical Security: Safe storage of paper documents containing account details.
Personnel & Access Controls: Restricted access to sensitive data.
Network Security: Secure storage, encryption, and distribution of protected information.
Communication Groups:
Non-Compliant: No response to previous audit.
Recertifying: Previously compliant merchants.
Net New: Newly identified merchants with opt-out options.
Remediation: Submitted audit, but not fully compliant.
Non-Compliance Fee:
Merchants failing to submit the audit are charged $69.99.
General Best Practices for Merchants
To stay compliant and secure, merchants should follow these recommendations:
Internal Preparation:
Assign a clear point of contact responsible for audit submission.
Engage third-party vendors if internal resources are insufficient.
Maintain thorough records of customer authorizations and data access policies.
Security Measures:
Encrypt all electronically stored consumer banking data.
Restrict data access to personnel with a business need.
Securely dispose of or store physical records.
Account Validation:
Account Validation is required for all WEB debits:
Used on first transaction or if account details change.
Acceptable methods include prenotification, micro-deposit verification, or third-party validation services.
Why Is Compliance So Important?

Reduces fraud across the ACH network.
