Frequently Asked Questions

How does a subscription work?

A monthly subscription of 5,000 lookups is good for either 5,000 lookups or for one month, whichever comes first. A subscription runs for either the number of lookups or for the period of time specified.

How about a one-time subscription?

Easy! After your purchase, select "Off" from the Auto-Renew Plan's dropdown list on the subscription page.

What happens when a subscription runs out?

It renews at the same level as your current plan unless you have specified another plan or have turned the renewal off. Need to change plans? Change it on the subscription page.
