Yeah, I don't know if it is an absolute requirement (probably not) but all the checks I have been issued by the bank and almost all the ones I have received from others have it. For personal checks, I think the store usually checks that the address matches your photo ID--for corporate checks the address is usually just a P.O. Box. I think the address is also used to look up people in the check acceptance risk system (certegy, chexsystems, etc).
