What is Alliant Credit Union’s Routing Number 2026?

Alliant Credit Union, originally known as the United Airlines Employees’ Credit Union since its establishment in 1935, has emerged as a trusted financial institution managing over $17 billion in assets for more than 700,000 members. Understanding Alliant’s routing number is pivotal, especially for wire transfers, and this guide provides comprehensive insights into its utilization.

Routing numbers, also known as ABA or routing transit numbers, serve as unique identifiers during financial transactions, such as wire transfers. Introduced by the American Bankers Association in 1910, these numbers streamline the processing of transactions by identifying the destination of checks and facilitating online and phone payments.

While Alliant Credit Union utilizes a single routing number, it’s common for large banks to employ multiple routing numbers, particularly due to mergers, acquisitions, and geographic expansions. Institutions like Wells Fargo and Bank of America may have different routing numbers for various states.

Locating a routing number on a check is straightforward. Simply examine the lower-left corner of the check, where the routing number is printed horizontally alongside the account number.

Unlike many other financial institutions, Alliant Credit Union does not use a SWIFT code for international wire transfers. Instead, the sender must utilize Alliant’s routing number (271081528) when initiating an international transfer. To send an international wire transfer from an Alliant account, customers must complete an international wire transfer authorization form, fax it with a copy of a government-issued identification, and contact the credit union’s customer service line for further instructions.
