Ask HN: what is your opinion about identity verification? necessary?

My startup is a peer to peer marketplace. I have been thinking about how to build trust and safety in the marketplace. One of them is to do an offline identity verification such as ID card, passport, driver license, etc.

What do you think of ID verification? is it necessary? How do you build trust and safety?

Also, I have been researching about firms that do ID verification. I know that Jumio, miicard and LexisNexis are some of them. Jumio is used by airbnb, so I contacted Jumio and a rep replied to my inquiries immediately and asked several questions. I answered that my startup is in stealth mode and, since then, it’s blank, 3 weeks have passed and no more update, I even sent a follow up email a week ago and to no avail. It seems like Jumio does not want my business.

So now I am considering LexisNexis and/or miicard as an alternative.

Have anyone use identity verification service with them and can you share your experience with them integrating it with your startup?

Thanks.
