In the early 1990's Wells Fargo originally had a single routing number (121000248) for all transactions: paper, EFT, wire. When they purchased Great American Bank they acquired that banks routing number, 122000247, and applied it to all Southern California accounts, while using the original number for N Cal, and wire transactions to all accounts. As Wells Fargo merged with other banks and grew out of California, more and more routing numbers were acquired, with some discarded, and others kept.
121000248 is still used for paper transactions in N. CA, and all bank wires. 122000247 is still used for S. CA accounts. 121042882 appears to be the routing number of choice for most (but not all) EFT transactions.
