Rather late, but we at NetToolKit have invested a lot to build a geocoding comparison tool (released late 2018). The tool is primarily oriented around comparing accuracy of results (you can see how far one result is from other results by clicking on it and checking the legend), but the table below also highlights cost differences and differences in terms of ...

Technically you can stack Tiger and OSM databases into one giant server and build them inside Nominatum OSM. Tiger can be imported easy and it complements the OSM server.
Whoever, the quality of the data you will be getting back is not going to be rooftop. OSM lacks accuracy for street addresses in USA. In some occasions I have seen it as far as 90 miles ...

In general, you'll find that geocoders have to work with their own database, and cannot be linked to an existing one. There are too many combinations of configuration parameters, table schemas, etc to handle.
However, exporting data into a format that can be imported into a geocoder's database is usually possible.
For Pelias, the csv-importer was designed ...

Try Open Addresses database. It has over 500 million records. It is available for download here.
The good part is that it has data from all world regions.
I suggest you start with Latin America as it is one of the hardest nuts to crack when comes to address testing. Then do Europe, then Asia. Leave the USA for last as addresses are most standardized there ...

For sure you have to geocode a very large amount of data.
It depends for which country you are requesting the coverage. I presume it is USA. In that case North America OSM database for Nominatum can help. However, because you are working with voter files that require precision or 1.0 accuracy (rooftop), that is not going to work. Also, none of the other ...

Geocoding means that an address is transformed into geographic coordinates like latitude and longitude. Consequently, if you have an address, but you want to know the mathematical location for that address, this process is called geocoding. Address geocoding is a sub layer of geocoding since geocoding can be used also for different places or locations on ...

Nominatim gives the bounding box (max/min latitude and longitude) using the api. see this

"boundingbox":["35.155971","35.156072","-117.79738","-117.792992"],

I would use the tiger geocoder as a backup and create your own geocoder using OpenAddresses.io data and full-text search in postgres.
