§501.11. Reporting Postage Evidencing System security weaknesses. — Inbound Citations

(a) An authorized Postage Evidencing System provider may be responsible to the Postal Service for revenue losses caused by failure to comply with § 501.11.

(b) As provided in § 501.11, the provider has a duty to report security weaknesses to the Postal Service to ensure that each approved Postage Evidencing System protects the Postal Service against loss of revenue at all times. A grant of approval of a system does not constitute an irrevocable determination that the Postal Service is satisfied with the revenue-protection capabilities of the system. After approval is granted to manufacture and/or distribute a Postage Evidencing System, no change affecting its basic features or safeguards may be made except as authorized or ordered by the Postal Service in writing.
