Try Again
I had thought the same thing, until someone told me that I could use just the TAC number to get information from the STOA website. I tried it and could get the information about a car, using only the TAC number.
Here is how I did it. I went to STOA's TAC webpage (
https://sunbeamtiger.org/index.php/component/content/category/16-club). Then I clicked on
TAC List. Near the bottom of the resulting page, I typed in the TAC number into the box next to "Cert #:" and then hit my enter button. Below the different possible inputs is the information about the car whose TAC number was just inputted. That info includes Cert #, VIN #, VIN Suffix, Color Code, Date, City, and License.
