That is interesting. The 1099-G is to include the payor's name, address, and federal EIN information. Contact California's Employment Development Department and ask for this information. You will need it to complete your tax return.
EDD Contact: 1-866-401-2849, Monday through Friday, between 8 a.m. and 12 noon (Pacific Time).
You could also view the form online (if you haven't done so already). Maybe the online form has the information you need.
The EDD page says "You can view, print, or request an official copy of your Form 1099G information for up to the past five years by accessing your UI OnlineSM account. Visit www.edd.ca.gov/UI_Online or to learn more view our helpful video tutorial."
