How to find a WWI soldier's ASN

[Titanfan]

Is there a website for finding a WWI soldier's army serial number?

If you have a full name, it may be possible on the pay sites FOLD3 and Ancestry, as these numbers may be found on departing/arriving ship's rosters, various unit/veterans documents, etc.

Or list what information you have here. I've had great luck with the search capabilities of fellow collectors who frequent this site.

Thank you gentlemen! I will scour the site above. I didn't have any soldier in particular in mind, but I come across names and unless I find a dog tag with it, it's always a curiosity.
