Is swift code used for ACH?

In the realm of finance and cryptocurrency, understanding the nuances of payment systems is crucial. So, I must ask: is the SWIFT code utilized for Automated Clearing House (ACH) transactions? The SWIFT code, often associated with international bank transfers, facilitates secure communication between financial institutions. However, ACH, on the other hand, is a domestic network that handles electronic payments and direct deposits in the United States. Does the SWIFT code, which facilitates cross-border transactions, have any relevance or application within the confines of the ACH system? This question begs for clarity, especially in today's interconnected financial landscape.
