The California Franchise Tax Board issued guidance clarifying that the Secretary of State's new 12-digit alphanumeric entity identification numbers require only numeric digits for tax filings and payments. Taxpayers using software or FTB's Web Pay application must enter only the numeric portion, as the system will reject alpha characters, dashes, or spaces.
