Electronic Funds Transfer Payments to AT&T

AT&T offers Business Customers, Bill Payment Consolidators, and Government Agencies the option to send (push) Electronic Funds Transfer (EFT) payments to AT&T via the Automated Clearing House (ACH).

AT&T's Inbound Corporate Payment (ICP) process is the receipt of national standard ACH transmissions that include remittance information as addenda records. This process involves a "push only" action from business customers, resulting in the following benefits:

  • Complete control of the accounts you wish to pay.
  • Complete control in how much you want to pay on each account.
  • Complete control of when you make a payment.
  • The ability to generate ACH files from Accounts Payable systems, creating the opportunity to integrate the payment process with your internal reporting systems.

As a corporate-wide AT&T process, ICP accepts electronic payments for the vast majority of AT&T accounts.

The 3 step enrollment process to send ACH payments to AT&T is outlined below:

1 - Complete and return the AT&T EFT/ACH Payment Registration form (ECF11)

    The purpose of this form is to provide AT&T with the critical information required to securely identify and accurately process payments received. To request a copy of this form, please send an email to the ICP Enrollment mailbox.

2 - Non-production testing

    AT&T processes all ACH transactions and addenda records internally. Therefore, AT&T must test prior to providing its banking information. Testing is done using a live "penny test" in a "test only" environment.

3 - Implementation - AT&T Banking Information (ECF12)

    After successful non-production testing, AT&T banking information is provided on an AT&T authorized form (ECF12).

AT&T offers daily Customer Error Correction (CEC) reports.

  • ICP: Unpostable Transactions - This report lists transactions that failed to post due to invalid remittance information. You are asked to provide additional information to assist with posting.
  • ICP: Corrected Transactions - This report lists transactions received with invalid or previous customer account numbers that AT&T was able to identify and correct in order to allow payments to post. The corrected account numbers should be updated in your system to prevent future payment posting delays.
