Routing Number 103103396

Routing number 103103396 is assigned to Firstbank, a main office located at P.o. Box 458, Antlers, Oklahoma 74523. This nine-digit ABA routing transit number identifies Firstbank within the Federal Reserve's Kansas City district for processing ACH payments, direct deposits, wire transfers, and check clearing.

The first two digits (10) indicate the Federal Reserve Bank of Kansas City, digits 3-4 (31) identify the processing center, digits 5-8 (0339) are the institution identifier, and the final digit (6) is a checksum that validates the entire number using the ABA's modulus-10 algorithm.

To set up direct deposit with Firstbank, provide your employer with routing number 103103396 along with your account number. Your account number is separate from the routing number and can be found on the bottom of your checks (to the right of the routing number), in Firstbank's mobile app, or in online banking under account details.

You can verify this routing number on the bottom-left corner of any check from Firstbank, in the mobile app, or by calling 580-298-3368. Direct deposits using this routing number are processed through the Automated Clearing House (ACH) network and typically post within 1-2 business days.

Routing number 103103396 is registered for ACH transactions at Firstbank, including direct deposits, bill payments, payroll, and recurring transfers. ACH payments are processed in batches through the Federal Reserve and typically settle in 1-2 business days.

For domestic wire transfers, Firstbank may use a different routing number. Wire transfers are processed individually through the Fedwire system and settle same-day. Always confirm the correct wire routing number with Firstbank before initiating a wire — using an ACH routing number for a wire can cause the transfer to be rejected or delayed.
