PMB Compliance Checklist for Mailbox Operators
Your Complete Guide to Pre-Audit Readiness and Ongoing Compliance Maintenance
Running a compliant CMRA isn't about memorizing regulations—it's about building systems that make compliance automatic. The operators who face enforcement actions aren't usually willfully breaking rules. They simply lack organized processes for maintaining compliance over time.
This guide provides everything you need: a printable master checklist, detailed pre-audit preparation steps, and a framework for ongoing compliance maintenance. Bookmark this page, print the checklists, and use them to protect your business.
Why You Need a Compliance Checklist
Compliance failures rarely happen all at once. They accumulate:
- A customer's PS Form 1583 expires and nobody notices
- A new employee forgets to verify two forms of ID
- Marketing materials slip back to "Suite" language
- Record storage becomes disorganized during a busy season
A systematic checklist catches these issues before USPS does. Operators who use compliance checklists report:
- 90% faster audit completion when USPS reviews their records
- Fewer customer complaints about mail delivery issues
- Lower staff training costs with clear procedural documentation
- Peace of mind knowing an audit would find nothing wrong
The Master PMB Compliance Checklist
Use this comprehensive checklist for self-audits and pre-audit preparation. Each section addresses a critical compliance area.
Section 1: PS Form 1583 Management
The PS Form 1583 is the foundation of CMRA compliance. Every customer must have a complete, current form on file.
Initial Customer Onboarding
- PS Form 1583 is completed in full (no blank required fields)
- Customer's printed name matches identification exactly
- Signature is present and dated
- Form includes both start date and duration/end date
- Two forms of acceptable identification were verified
- At least one ID contains a photograph
- ID numbers and expiration dates are recorded on the form
- Employee who verified IDs signed and dated the form
- Original form (or certified copy) is retained on-site
ID Verification Standards
- Primary ID is government-issued with photo (driver's license, passport, state ID)
- Secondary ID is from approved list (credit card, utility bill, lease, etc.)
- Both IDs are current and not expired at time of verification
- ID information matches between both documents
- Photocopies of IDs are retained with the 1583 (if store policy)
- Business customers provide additional business documentation
Annual Renewal Process
- System tracks expiration dates for all customer forms
- Renewal reminders sent 60 days before expiration
- Follow-up reminders sent 30 days before expiration
- Final notice sent 14 days before expiration
- Expired forms are flagged in the system immediately
- Customers with expired forms are notified of service impact
- Renewed forms include fresh ID verification
- Old forms are archived according to retention policy
Section 2: Address Formatting Compliance
Every customer address must use the correct PMB designator format.
Customer Address Records
- All addresses use "PMB" or "# " (with space) designator
- No addresses use "Suite," "Apt," "Unit," or other non-compliant formats
- Address format is consistent across all customer records
- Database/software defaults to PMB format for new customers
- Legacy customers have been converted to PMB format
Customer Communication
- Welcome materials explain PMB format requirement
- Customers receive written documentation of their correct address
- Address change instructions explain why PMB is required
- Staff can articulate the importance of PMB to customers
Marketing and Signage
- Website uses only PMB format in all examples
- Printed marketing materials use PMB format
- In-store signage references PMB, not Suite
- Social media and online listings show PMB format
- No "Suite address" or similar language appears anywhere
Section 3: Record Keeping and Storage
Proper record organization is essential for audit readiness.
Active Customer Files

Digital Record Management

Common Compliance Gaps and How to Close Them
Even well-intentioned operators often have these gaps:
Gap 1: Expiration Tracking Failures
Problem: Forms expire without renewal because nobody is tracking dates.
Solution:
- Implement automated expiration tracking in your software
- Generate weekly reports of upcoming expirations
- Assign specific staff member responsibility for renewals
- Create escalation procedures when customers don't respond
Gap 2: Inconsistent ID Verification
Problem: Different employees apply different standards for ID verification.
Solution:
- Create a physical checklist posted at every intake station
- Include visual examples of acceptable vs. unacceptable IDs
- Require supervisor sign-off on first 10 verifications for new employees
- Conduct regular spot-checks of ID documentation
Gap 3: Address Format Drift
Problem: Suite addresses creep back into use over time.
Solution:
- Configure software to reject non-PMB formats
- Remove Suite from any dropdown menus or templates
- Include address format in regular staff training
- Audit marketing materials quarterly
Gap 4: Disorganized Records
Problem: Files can't be located quickly during an audit.
Solution:
- Implement consistent filing system (alphabetical, numerical, or hybrid)
- Create index or log of all customer files
- Conduct monthly organization spot-checks
- Assign specific responsibility for file maintenance
Gap 5: Training Documentation Missing
Problem: No proof that staff were trained on compliance requirements.
Solution:
- Create training acknowledgment forms
- Maintain training log with dates and signatures
- Include compliance in written job descriptions
- Conduct documented competency assessments
Emergency Compliance Response
When you discover a compliance issue or receive USPS notice:
Immediate Steps (First 24 Hours)
- Document the issue in writing with date and details

Short-Term Response (First Week)

- Communicate with affected customers if necessary
- Begin corrections starting with highest-risk issues
- Document all corrective actions taken
- Respond to any USPS notices within required timeframes
Follow-Up (First Month)
- Complete all remediation according to plan
