The door hangers are audited by Verified Audit Circulation, a nationally licensed audit provider for the public, to confirm the amount is printed and distributed in full. We use a statewide distribution company that is insured and permitted and has a Houston based corporate office. The door hangers are inventoried two times daily during the distribution period. Our distributor notifies your account executive at the start of distribution for their territory(s). Daily deliveries, work logs and verification forms are reviewed for due diligence. Random checks are performed daily to ensure compliance and integrity.
