CMRA certification is due four times a year: January 15, April 15, July 15, and October 15. USPS now requires every customer's Form 1583 information in the CMRA Customer Registration Database, and the USPS Office of Inspector General's June 2025 audit found widespread CMRA non-compliance.
This center translates the rulebook: Form 1583 execution, ID rules, CRD duties, certification deadlines, PMB addressing, and termination obligations, each cited to the exact DMM section so you can check our work.
A print-friendly, one-page checklist of the DMM 508.1.8 duties: what to collect before you accept a customer, what goes in the CRD, what to keep doing every quarter, and which records to retain.
Each guide covers one USPS requirement end to end: what the DMM says, the traps operators fall into, and the questions inspectors actually ask.
Who signs, who witnesses, and what makes a Form 1583 valid: physical or live-video presence, notarized acknowledgment, one form per addressee, and the address checks USPS expects you to run.
Read the rulesThe two-ID rule in plain English: acceptable primary photo IDs, acceptable secondary IDs, the documents USPS rejects outright, and why expired IDs quietly break your compliance.
Read the rulesWhat the CRD is, how a CMRA registers with Form 1583-A, exactly what you must upload for every customer, and what happens when USPS flags a record as deficient.
Read the rulesCertification is due January 15, April 15, July 15, and October 15. What you are actually attesting to, how to prepare in the two weeks before each deadline, and what a miss costs.
Read the rulesThe exact address formats USPS allows for private mailboxes, the Suite and Unit designators it prohibits, and side-by-side compliant versus non-compliant examples.
Read the rulesThe obligations that outlive the customer: recording the termination in the CRD, keeping the Form 1583 for six months, and the six-month remail duty most operators have never heard of.

January 15, April 15, July 15, and October 15, every year. You certify that every Form 1583 on file is current, all termination dates are recorded, and no ID document is expired.
Yes. Signatures can be witnessed in the physical or virtual real-time audio/video presence of an authorized CMRA representative, or acknowledged before a commissioned notary, including a remote online notary.
Two forms of ID: one acceptable primary photo ID and one acceptable secondary ID, both current and traceable to the applicant. Social Security cards, birth certificates, and credit cards are never acceptable.
Record the termination date in the CRD, retain the Form 1583 for at least six months, and remail the former customer's mail for at least six months with new postage. There is no 60-day rule, despite the folklore.
