One doesn't "get" a COLB (Certification), in the sense that it is a source document. It's an abstract, issued upon request, reflecting some of the data on some source document already on file, generally a Certificate of Live Birth, but also possibly a "Certificate of Hawaiian Birth". Additionally there are multiple ways to "get" a Certificate other than being born in a hospital in Hawaii.
OK , so you make your phone call and give the information necessary to fill in a COLB form (even though it isn’t going onto that paper form directly) and that creates a (computerized? which in 196x would mean a punched card) data record from which a paper COLB can be generated upon request ,, not the paper COLB itself; not much of a distinction.
