You want to to find your Streamlined Sales Tax Program ID (SSTPID)

Note: All Streamlined Sales Tax (SST) states are required to file on a monthly basis, filing a Simplified Electronic Return (SER) under ONE registration ID (SSTID) for all SST States. Each state will still have specific account numbers, but Avalara does not keep these on file since we do not file under these. If you need the specific state ID, please contact the states individually.
