Certification that's true before you sign it.
Every mailbox customer needs a current USPS Form 1583, and your store must certify its customer records every quarter. Postern verifies your customers in person or over live video, keeps every ID current, and files the certification in one click — so when it's time to attest, the records already support what you're signing.
"Not audited yet" isn't the same as safe.
Most stores hold compliance together with a spreadsheet and hope. Every mailbox customer needs a completed Form 1583, their information and IDs entered into the USPS database, every ID kept current, and closed mailboxes updated — and then the entire list certified again every quarter.
Today that means re-keying records into a government website, uploading ID documents one at a time, tracking expiration dates by hand, and trying to confirm whether each submission went through. Your counter software doesn't handle it, and your mailbox software may only handle its own customers. The rest falls back on you.
The stakes go beyond paperwork: continued noncompliance can lead the USPS to suspend mail delivery to your store, affecting every mailbox customer, not just one. That quarterly knot in your stomach doesn't have to be part of the job.
File the quarter in one click
Submit your quarterly USPS certification in one click — the whole backlog if you're catching up — with a clear filing status and confirmation it was received.
Verify in person or over live video
Capture the ID, confirm the customer, and witness the Form 1583 signature — at your counter or over live video, by your own authorized staff, exactly as USPS rules allow. No visit required.
Know before an ID expires
An expired ID quietly makes a customer non-compliant. Postern monitors every expiration and flags it before it lapses — you're notified, you don't go hunting.
Keep the paper trail ready
Every verification and filing is logged, timestamped, and tied to the staff member who did it. If a record is reviewed, the full trail is already in one place.
You attest; Postern handles the busywork
The certification stays yours: your staff verifies and signs. Postern organizes the records, surfaces the exceptions, and submits — so you decide without doing every step by hand.
Onboard customers from anywhere
Live-video verification means a customer never has to visit. Verify across the country or the world with your own staff — a market far beyond your area, and the relationship stays yours.
Getting compliant takes about a year. The quarter doesn't wait.
Quarterly certification is a recurring USPS requirement. A spreadsheet may help you track the work, but it doesn't complete the customer records, update the USPS database, replace expired IDs, or submit the certification for you. If your records have piled up over months or years, bringing every file current takes time — so starting before the next deadline gives your staff room to resolve missing forms, expired IDs, and closed mailboxes without another last-minute scramble. Postern turns compliance from a quarterly emergency into a monitored, repeatable routine.
