Code of Federal Regulations Title 39. Postal Service § 39.501.8 Postage Evidencing System test and approval

(a) To receive Postal Service approval, each Postage Evidencing System must be submitted by the provider and evaluated by the Postal Service in accordance with the Intelligent Mail Indicia Performance Criteria (IMIPC) published by Commercial Payment. Copies of the current IMIPC may be requested via mail to the address in § 501.2(f). These procedures apply to all proposed Postage Evidencing Systems regardless of whether the provider is currently authorized by the Postal Service to distribute Postage Evidencing Systems. All testing required by the Postal Service will be an expense of the provider.

(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.
