Merchant ID & Sandbox

I've seen a couple questions on here about finding your Merchant ID (for example: Need Merchant ID ) - but there don't seem to be any resolutions. So I'll ask my own question!


We're working on setting up a gateway to use Vantiv, either custom built or using WooCommerce. In looking at the WooCommerce plugin, I see there's a space for Merchant ID. This is separate from User ID, which I assume is the one they use to log in at


How do we get a Merchant ID? Is it something I can find under their account on Or is it something we get when we sign up at Vantiv eCommerce Certification - New Organization Registration ? They're a current customer, so I hesitate to go through the "New Organization Registration" process unless we need to.
