The Check Clearing for the 21st Century Act, commonly known as Check 21, went into effect October 28, 2004. It was designed, in part, to improve the overall efficiency of the U.S. payment system. It supports the creation of a document called a substitute check.
Comerica will accept and process substitute checks. We are committed to supporting the evolution of the U.S. payment system and will continue to invest in image capabilities that provide new features, products and services for our customers.
