Understanding your bank’s ACH routing number is important for sending and receiving ACH payments properly. This article provides an overview of ACH routing numbers and specifics on the routing number for SECURITY BANK.

What is an ACH Routing Number?

An ACH routing number is a 9-digit code that identifies the bank where a checking account is held. It is used to route payments through the Automated Clearing House (ACH) network, which facilitates electronic payments and money transfers.

ACH routing numbers are also sometimes referred to as ABA routing numbers or routing transit numbers (RTNs).

Why Do You Need the Routing Number?

The routing number is essential for sending or receiving ACH payments to/from a bank account.

For direct deposits, such as payroll, you need to provide the employer or payer with your account number and routing number. This allows them to initiate an ACH credit to your account.

For direct debits, such as bill payments, you provide the billing company with your account and routing number. This authorizes them to debit your account.

Without the correct routing number, ACH transfers cannot be processed properly. The routing number tells the ACH network where to direct the funds.

Where to Find the Routing Number

There are a few places you can find the ACH routing number for your bank account:

On a Check

At the bottom left corner of a check, there is a 9-digit number to the left of the account number. This is the ABA routing number that is used for ACH transactions.

Online Banking

Most banks list the ACH routing number for each account in online banking. It may be shown under account settings or details.

Contact Your Bank

You can also call or visit your bank to ask for the official ACH routing number on your account. A bank employee can provide or confirm the number.

What is the ACH Network?

Before diving into the specifics of SECURITY BANK’s routing number, it helps to understand how the ACH network functions.

Automated Clearing House

The ACH network is an electronic funds transfer system that facilitates payments in the United States. ACH payments move funds between banks through the Automated Clearing House network.

It is run by the National Automated Clearing House Association (NACHA) and the Federal Reserve Banks. It allows for efficient, cost-effective direct debit and credit transactions.

How ACH Transactions Work

ACH payments follow a standard process:

ACH Credit Transactions

  • The originating bank receives payment instructions from the account holder. This could be an individual or a company initiating direct deposits.
  • The originator sends ACH credit files through the ACH network to the receiving bank.
  • The receiving bank credits the funds into the designated account. For example, an employer initiating payroll.

ACH Debit Transactions

  • The originating bank receives debit authorization from the account holder. For instance, to pay a utility bill.
  • The originator sends ACH debit files to the receiving bank through the ACH system.
  • The receiving bank debits the account and forwards the funds to the originating bank.

The transactions are settled efficiently through the network’s clearing and settlement process.

ACH Network Participants

There are three core participants in ACH payments:

Originating Depository Financial Institutions

The banks that receive payment instructions and send ACH transactions through the network.

Receiving Depository Financial Institutions

The banks that receive ACH transactions and credit or debit the receiver’s account accordingly.

Federal Reserve Banks

The Federal Reserve acts as the central clearing facility, settling entries and funds movement between participating banks.

Understanding the Components of an ACH Routing Number

ACH routing numbers are comprised of three components:

ABA Routing Number

This 9-digit identification code identifies the financial institution. It is assigned by Accuity, the official registrar of ABA institution codes.

Institution Code

This identifies the specific branch or location of an institution. It is assigned by the financial institution.

ABA Check Digit

This is a mathematical formula that validates the ABA routing number. The check digit enables errors to be detected.

How to Validate an ACH Routing Number

To ensure you have a valid routing number, there are two methods to validate it:

Modulus Check

This checks that the ABA routing number conforms to the modulus 10 formula used in the check digit.

You can use an online modulus checker tool for validation.

Lookup Tools

You can also validate against ABA routing number directories, such as the Federal Reserve Financial Services reference tables.

This allows you to lookup the institution and branch associated with the routing number.

Common Uses of ACH Routing Numbers

ACH routing numbers are integral to several common types of ACH transfers:

Direct Deposit of Payroll

Employers can send payroll funds to employee accounts using ACH credits and the employees’ account/routing numbers.

Direct Debit of Bills and Payments

Consumers can authorize deductions from their checking account to pay bills such as utilities. ACH debits pull the funds using account and routing numbers.

Business-to-Business Payments

Companies can pay vendors and conduct other B2B transactions efficiently over the ACH network using routing numbers.
