Authorized shares on Delaware Corporations Don't pay $20 to find out the authorized shares. 1. Go to: https://sos-res.state.de.us/tin/controller then search for the corporation. 2. Obtain the corporation number. 3. Dial 1-302-739-3073. When the recording answers, dial "8" then enter the corporation number and the computer will tell you for free. 4. You save $20. Send me half to thank me! LOL.
