Sovereign Bank Routing Number: Santander Transition Guide

What is the Sovereign Bank routing number?

Sovereign Bank used routing number 231372691 for its Pennsylvania-based accounts, with additional routing numbers for branches across the northeastern United States. Sovereign Bancorp was one of the largest savings institutions in the country before its acquisition.

Banco Santander, the Spanish banking giant, acquired Sovereign Bancorp in January 2009 and subsequently rebranded all Sovereign Bank branches as Santander Bank in October 2013. The rebranding unified Santander's U.S. operations under a single brand.

Santander rebranding and routing numbers

When Sovereign Bank was rebranded as Santander Bank, many existing routing numbers were retained to minimize disruption for customers. The routing number 231372691 may still be valid for some Santander accounts that were originally Sovereign Bank accounts.

However, Santander has since introduced its own routing numbers in various markets. Your current routing number depends on when your account was opened and whether it has been migrated to a newer Santander routing number.

How to find your Santander routing number

Log into Santander Online Banking or the Santander Mobile app to verify your current routing number. Santander displays routing numbers in the account details section of its digital banking platforms.

You can also find your routing number on Santander checks, by calling Santander at 1-877-768-2265, or by visiting a Santander branch. Santander's primary routing number is 231372691, but confirm your specific account details.

Sovereign Bank history

Sovereign Bancorp was founded in 1984 in Wyomissing, Pennsylvania, and grew rapidly through acquisitions to become one of the top 20 banks in the United States. The bank operated approximately 750 branches across the northeastern states.

Santander initially acquired a minority stake in Sovereign in 2005 before completing the full acquisition in 2009. The transition from Sovereign to Santander marked the end of one of the largest independent thrift institutions in the U.S.
