AB & T Routing Numbers — Complete State Directory
AB & T is registered with the American Bankers Association (ABA) and participates in the US ACH and Fedwire payment networks across 1 states. Every ABA routing number is a unique 9-digit code that identifies AB & T (or a specific state office of AB & T) within the Federal Reserve's payment infrastructure. BankZop's AB & T routing number directory covers all 2 active routing records, sourced from the official ABA routing registry and the Federal Reserve E-Payments Routing Directory.
You need the correct AB & T routing number whenever you set up direct deposit for payroll, register your account for ACH bill payments, provide banking details for tax refunds, or initiate a domestic wire transfer. Selecting the wrong routing number — particularly for a different state — can result in rejected transactions or delayed payments.
What is the Routing Number for AB & T?
AB & T has 2 routing numbers registered across 1 states. Unlike smaller community banks that operate with a single routing number nationwide, large institutions like AB & T maintain state-specific routing numbers — a legacy of the regional banking structure established when the ABA routing system was created in 1910. Your AB & T routing number is determined by the state where your account was originally opened, not your current address.
The 9-digit ABA routing number encodes three components: the Federal Reserve district (digits 1–4), the ABA institution identifier (digits 5–8), and a mathematical check digit (digit 9) that allows computers to instantly detect entry errors. Select your state above to find the exact routing number for AB & T in your state.

When You Need the AB & T Routing Number
Direct Deposit Setup
When setting up payroll direct deposit, IRS tax refunds, Social Security benefits, or any other recurring payment to your AB & T account, you must provide your routing number alongside your account number. Your employer or the paying agency uses these details to initiate an ACH credit that deposits funds directly into your account on the scheduled date. Use the correct state-specific AB & T routing number — the one assigned to the state where your account was opened.
ACH Transfers and Bill Payments
ACH is the backbone of US electronic payments — used for online bill payments, subscription services, peer-to-peer transfers, and business payroll. When you authorise a company to debit your AB & T account electronically, you provide the AB & T routing number and your account number. The ACH network, governed by NACHA, uses the routing number to direct the debit or credit to the correct financial institution. Standard ACH settles in 1–2 business days; Same Day ACH settles same-day for transactions submitted before the cut-off.
Domestic Wire Transfers
Domestic wire transfers move funds in real time through the Federal Reserve's Fedwire system and settle on the same business day. Important: AB & T may use a different routing number for wire transfers than for ACH. Always confirm the correct wire routing number with AB & T's wire department before initiating a wire — using the ACH routing number for a wire transfer may cause it to be rejected or delayed. For international wire transfers, you need the AB & T SWIFT/BIC code instead of the routing number.
Check Payments
The routing number printed on your AB & T checks is the same as your ACH routing number. When you write a check, the routing number in the MICR line at the bottom allows the Federal Reserve's check clearing system to identify AB & T as the paying bank and route the check back for settlement. Paper check processing has declined significantly with ACH adoption, but routing numbers remain essential for check payment infrastructure.
AB & T Routing Number vs Account Number — Key Differences
These two numbers are always required together for any ACH or wire transaction. They are easy to confuse — here is exactly how they differ:
| Feature | AB & T Routing Number | AB & T Account Number |
|---|---|---|
| Identifies | AB & T as the institution | Your specific account at AB & T |
| Length | Always 9 digits | Varies (typically 10–12 digits) |
| On a Check | Bottom-left, first sequence | Bottom-center, second sequence |
| Shared? | Same for all accounts in your state | Unique to your individual account |
Never share your account number more than necessary — it gives access to your specific account. Your routing number is public information (all AB & T customers in your state share it), but your account number must be protected. For international transfers, neither the routing number nor account number is sufficient alone — you also need the AB & T SWIFT code.
