Understanding Webster Bank's Multiple Routing Numbers
Webster Bank has multiple routing numbers due to its history of strategic acquisitions and growth. Founded in 1935 as First Federal Savings of Waterbury by Harold Webster Smith, the bank has acquired several financial institutions over the decades, including NewMil Bank in 2006 and Sterling National Bank in 2022. Each acquisition brought existing routing numbers into Webster's system.
The bank consolidated many routing numbers following its $10 billion merger with Sterling National Bank in 2022, when Webster also moved its headquarters from Waterbury to Stamford, Connecticut. However, some legacy routing numbers remain active to ensure uninterrupted service for existing customers.
Important Note About Legacy Routing Numbers
Webster Bank officially recommends using routing number 221970443 for all new transactions. However, if you've been successfully using a different Webster Bank routing number, you can continue to do so. All checks and payments using your existing routing number will continue to work without interruption.

FAQs
Common questions about ACH and wires through Webster Bank
Why does Webster Bank have multiple routing numbers?
Webster Bank's multiple routing numbers reflect its 90-year history of growth through strategic acquisitions. The bank started as First Federal Savings of Waterbury in 1935 and has acquired several financial institutions including NewMil Bank (2006), HSA Bank (2005), and most recently Sterling National Bank (2022) in a $10 billion merger. Each acquisition brought existing routing numbers into Webster's system. While the bank has consolidated many of these numbers, some legacy routing numbers remain active to ensure uninterrupted service for customers who opened accounts under previous bank names or in different states.
Can I use routing number 221970443 even if my checks show a different number?
Yes, Webster Bank officially recommends using 221970443 as the primary routing number for all customers. However, if your checks display a different Webster Bank routing number and it has been working successfully for your transactions, you can continue using it. Webster maintains multiple active routing numbers to ensure seamless service across its network. For wire transfers specifically, always use 221970443 regardless of what appears on your checks.
What's the difference between Webster Bank's ACH and wire routing numbers?
For ACH transfers and direct deposits, Webster Bank uses state-specific routing numbers based on where you opened your account (211170101 for Connecticut, 211370231 for Massachusetts and Rhode Island, or 021973019 for New York). For wire transfers, Webster Bank uses a single routing number - 221970443 - for all customers regardless of location. Wire transfers process same-day and cost $35 for outgoing domestic wires and $15 for incoming, while ACH transfers take 1-3 business days but are typically free or low-cost.
I moved from Connecticut to New York but kept my Webster Bank account. Which routing number do I use?
You should continue using the routing number associated with the state where you originally opened your account. If you opened your account in Connecticut, use 211170101 for ACH transfers even though you now live in New York. Your routing number is tied to your account's origin, not your current residence. For wire transfers, all customers use 221970443 regardless of where the account was opened or where you currently live.
Does Webster Bank's SWIFT code work for all international wire transfers?
Webster Bank's SWIFT code (WENAUS31) identifies the bank for international wire transfers. When receiving international wires, provide your sender with SWIFT code WENAUS31, your account number, and Webster Bank's full name and address. Outgoing international wire transfers cost $45 minimum and may include additional correspondent bank fees. Processing times for international wires typically range from 1-5 business days depending on the destination country and currency. Always verify international wire requirements by calling 1-800-325-2424 before initiating a transfer.
