Signature Bank Routing Number: Post-Closure Guide

What is the Signature Bank routing number?

Signature Bank used routing number 026013576 for its accounts before it was closed by regulators in March 2023. Signature Bank, based in New York, was the third-largest bank failure in U.S. history at the time of its closure, with approximately $110 billion in assets.

The FDIC created Signature Bridge Bank, N.A. to manage the transition and protect depositors. In March 2023, New York Community Bancorp (NYCB) acquired a substantial portion of Signature Bank's assets and deposits through its subsidiary Flagstar Bank.

What happened to Signature Bank accounts

Flagstar Bank, a subsidiary of New York Community Bancorp, assumed most of Signature Bank's deposits and certain loan portfolios. Former Signature Bank customers were transitioned to Flagstar Bank accounts, and new routing numbers were assigned as part of the migration.

If you were a Signature Bank customer, your account was moved to Flagstar Bank. The legacy routing number 026013576 should no longer be used for new transactions. Contact Flagstar Bank or log into their online banking platform to confirm your current routing number.

How to find your current routing number

Former Signature Bank customers should use the Flagstar Bank online banking portal or mobile app to view their current routing and account numbers. Flagstar Bank uses its own set of routing numbers, which vary by state and account type.

You can also locate your routing number on any new checks issued by Flagstar Bank, or by calling Flagstar customer service. Make sure to update any recurring payments or direct deposits with your new Flagstar routing number.

Updating direct deposit and automatic payments

After the transition from Signature Bank to Flagstar, it is critical to update your routing number with employers, billers, and any services that send or pull payments from your account. Using the old Signature Bank routing number may result in failed or returned transactions.

Contact your payroll department, utility companies, and subscription services to provide your updated Flagstar Bank routing and account numbers. Set up new wire transfer instructions with counterparties as well, since wire routing numbers may differ from ACH routing numbers.
