MUFG Union Bank has a rich history dating back to 1864 when it was founded as The Bank of California. The bank underwent a series of transformations, acquisitions, and name changes over the years. In 1914, Kaspare Cohn founded Kaspare Cohn Commercial & Savings Bank in Los Angeles, which was later renamed Union Bank & Trust Company of Los Angeles in 1918. In 1996, after several other name changes and acquisitions, it became known as Union Bank of California following a merger between Bank of Tokyo and Mitsubishi Bank, both having had their own share of acquisitions and mergers in the US banking landscape. Eventually, in 2008, it was rebranded as UnionBank and in April 2018, it was named MUFG Bank, Ltd. The bank was a subsidiary of the intermediate holding company, MUFG Americas Holdings Corporation, and a member of the Mitsubishi UFJ Financial Group. In December 2022, MUFG Union Bank was acquired by U.S. Bancorp for $8 billion, marking the end of its operation as MUFG UnionBank​.

The first 4 characters represent the bank's code, the next 2 denote the country, followed by 2 for the city. The remaining characters (which are optional) specify the bank's branch.
