Four times a year, every CMRA signs its name to a claim: our records are current, our closures are recorded, and no ID on file is expired. This page covers the exact due dates, what the attestation legally covers, and a preparation rhythm that makes each deadline a formality instead of a scramble.
Certification is due on the 15th of January, April, July, and October, covering the quarter that just ended. Put all four on the calendar now:
Under DMM 508.1.8.3, the quarterly certification is a three-part claim about your entire roster:
Notice what this means in practice: the certification is only as true as the quarter of record-keeping behind it. You cannot fix a quarter on the 14th.
Two weeks before each due date, run the same internal audit every time:
A store that runs this routine four times a year is also, as a side effect, permanently inspection-ready.
A lapsed certification puts the CMRA out of compliance. USPS can suspend a non-compliant CMRA from operating, and a deficiency left uncured for 30 days can end in termination of the CMRA authorization. The certification is also the moment your other gaps surface: an expired ID or an unrecorded closure you certify over is a false attestation, which is a worse conversation than a late filing.
Validate Form 1583 completeness with a structured checklist, risk scoring, and audit-ready notes.
