I own an online Classified where we allow users to post jobs, services, housing for rent, housing for sale, personals, items for sale, gigs, community, and discussion forums.  We know there are a lot of online criminals, fraudsters, spammers, and other illegal activities go on with Classifieds companies.  We wanted to ensure there was no illegal activity going on with our personals, services, and items for sale.  We also didn’t want spammers posting numerous ads on job sites, housing for rent or sale, and gigs.  We searched for an online security solution company and found a few that may work for our site.  Once we did some research we found Telesign’s PhoneID look up and Telephone Verification to be the best fit.  We also like the fact that there wasn’t a set up fee or monthly minimum charges to use Telesign.  Once we signed up we were able to start using Telesign that same day because there wasn’t any new hard ware to download.
