AT&T Account Numbers on ACH Payments
August 26, 2022
The SMART Team was recently contacted by AT&T regarding the information State of Kansas agencies are providing in the Invoice No field on SMART vouchers.
AT&T is receiving a significant number of payments with incorrect posting data. This can be account numbers that do not contain the full account number (e.g., missing the last 4 digits), account numbers including spaces, dashes, or other special characters), transposed account numbers, and missing account numbers (e.g., showing billing period in this field instead of the account number).
Your agency must follow the Invoice No format on all AP vouchers as described below so that AT&T can match the payment to the correct account.
If the Invoice No on the voucher does not match the AT&T Account Number, the payment falls to AT&T’s Unpostable Worklist, and this can result in a significant delay in posting the payment to the proper account.
AT&T also reminds us that “AT&T is not responsible for late fees/interruption of service due to incorrect posting details”.
The AT&T Supplier IDs which are authorized for ACH are:
XXXXXX4946 – AT&T
XXXXXX6465 – AT&T Corp
XXXXXX8973 – AT&T Datacom Inc
XXXXXX4964 – AT&T Mobility II LLC
XXXXXX9499 – AT&T National Compliance Center
AT&T utilizes the Invoice No field from the SMART voucher to correctly identify the account to which the payment shall be applied. An account can be properly matched to a payment only if agencies use the format exactly as described. Enter the full account number as it appears on the AT&T billing statement with no spaces, no dashes or other punctuation into the Invoice No field on the SMART voucher. Additional information may be included in the Invoice No field by placing an “X” after the account number and putting any other data after the “X” (up to 30 total characters).
If your agency has any questions about which field is the actual account number on an AT&T statement, please submit a Service Desk ticket along with a scanned copy of the first page of the statement.
The SMART staff is working with AT&T to receive a copy of their Unpostable Worklist, so that payment posting errors can be routed to agencies on a Service Desk ticket. Additional information on this process will be provided in the individual agency Service Desk tickets once we start receiving this report.
Please share this information with all agency staff who enter and approve SMART vouchers, so that we can provide the information which allows AT&T to post our State of Kansas payments as quickly as possible.
