My BC states that it is an exact replica of the original which is on file. There is much more info on it than 0’s apparently faked one; my parent’s names, address, occupations & for how long; mother’s maiden name, doctor’s signature, name of hospital, parents’ races & states where they were from, their ages; eyedrops given (silver nitrate?) Now this is a lot of info! compared to ZERO’s certif. I was born in CA, ‘37. Maybe Hawaii did it differently.
All certified copies of birth certificates are similar to BOs. If you requested your birth certificate from California, you would receive something very similar to the COLB that BO posted. They can be used for everything the other, long form birth certificates are used for.
