National Penn Bank Routing Number: Complete Guide

What is the National Penn Bank routing number?

National Penn Bank used routing number 031309123 for ACH transfers and direct deposits. National Penn Bank was a community bank headquartered in Boyertown, Pennsylvania, serving customers across southeastern Pennsylvania and surrounding areas.

National Penn Bank was acquired by BB&T in 2016, and BB&T subsequently merged with SunTrust to form Truist Financial. If you still have accounts associated with National Penn Bank, your routing number may have transitioned to a Truist routing number. Contact Truist to verify your current routing number.

How to find your routing number after the merger

If your National Penn Bank account has been migrated to Truist, your routing number has likely changed. Log into Truist online banking or the Truist mobile app to find your current routing number.

You can also check any new checks issued by Truist — the routing number is printed on the bottom-left corner. If you have not received new checks, contact Truist customer service for your updated routing number.

National Penn Bank wire transfers

Wire transfers previously processed through National Penn Bank are now handled by Truist. For domestic wires, you will need the current Truist routing number, your account number, and the name on the account.

International wire transfers require a SWIFT code. Contact Truist customer service for the current SWIFT code, processing times, and fee information for international transfers.

Direct deposit for former National Penn customers

If you previously set up direct deposit with routing number 031309123, you should update your payroll information with your new Truist routing number. Contact Truist or check online banking for the current number.

Updating your direct deposit details ensures that payroll deposits, tax refunds, government benefits, and other ACH payments continue to arrive without interruption.
