Sterling National Bank Routing Number: New York Banking Guide

What is the Sterling National Bank routing number?

Sterling National Bank used routing number 021908893 for ACH and electronic transfers. In 2022, Sterling Bancorp merged with Webster Financial Corporation, and Sterling National Bank customers were transitioned to Webster Bank. Former Sterling customers should verify their current routing number through Webster Bank.

Sterling National Bank was a prominent New York-based commercial bank serving businesses and individuals throughout the greater New York metropolitan area. The merger with Webster Bank created a combined institution with approximately $65 billion in assets and an expanded presence across the northeastern United States.

How to find your routing number after the Webster merger

Former Sterling National Bank customers should log into Webster Bank's online banking platform to confirm their current routing and account numbers. During the account migration, routing numbers may have been updated to Webster Bank's routing number.

Webster Bank provides multiple ways to locate your routing number, including online banking, the mobile app, printed checks, and customer service. If you are unsure about your routing number, visit a Webster Bank branch with valid identification.
