A SAM letter is most likely referring to the notarized letter that may need to be uploaded to SAM. The letter may have to be done only on a case-by-case basis. If you need to learn more about this, call the USBRI Help Desk at 1-888-646-9998 and a CRS will be able to help you.
USBRI has been offering filing assistance for over 11 years, constantly staying on top of any changes made with SAM and SBA. Using the number above, reach out to a CRS and ask about the registration process and the necessity of it to bid on contracts and grants.
