ContactCloud will not charge you twice for the same contact. If you have already revealed that contact's information, you may reveal it again as often as you'd like. If you have a shared pool of reveal and export credits (such as on our Starter plan), you may also export a contact whose info has already been revealed, or reveal a contact whose info has already been exported, without paying another credit. On plans with unlimited reveals but limited exports available, exporting a contact whose info has already been revealed will count against your export credits.
A contact is considered "the same" if it is the same person at the same company. Once the contact moves to a different company, we consider that a new contact and you will have to pay another credit to see their information.
