I never did understand why they would black out the certificate number - that was always a red flag to me. It makes no sense to black out the certificate number - you would just pull up the same document.
Unless you wouldn’t...
There is a photo online with the certificate number not blacked out (again, wish I could remember where I saw it. I roam the internet a lot and am not good at bookmarking my tracks). The explanation on the site I saw it was that at the time the Obama campaign released the scan they didn’t know if the cert. # was something that should be blacked out or not but have since learned it’s not necessary to block out.
But a pic of that cert. with the number intact is out there.
