Early Kings and Richmond County, New York Marriage Database
Note: the fee for copies of vital record certificates is now $18.50.
These are records from towns and villages before they were incorporated into New York City in 1898.
These "certificates" are Register Entries in a journal, and the numbers are probably Line Numbers.
The NYC website indicates that these journals are on microfilm and you have to contact them to arrange for access onsite.
There is a request form here: https://a860-collectionguides.nyc.gov/contact
