- In your online service dashboard: if you mailed through a provider
- On Return Receipt paperwork: PS Form 3811 (if you used the green card)

Quick status cheat sheet (what it usually means)#
These are the most common statuses senders ask about:
- Accepted / USPS in possession of item
- USPS has it. Your proof-of-mailing clock starts here.
- In Transit
- Moving through the network. Scan gaps are normal.
- Out for Delivery
- Delivery attempt today.
- Delivered
- Delivered with signature capture.
- If you purchased Electronic Return Receipt, the signature documentation is tied to the delivery record.
- Notice Left / Available for Pickup
- Delivery was attempted, but no one signed. USPS is waiting on the recipient.
- Unclaimed / Refused / Return to Sender
- The item is coming back to you.

Troubleshooting tracking problems#
"Status not available" / "Information not found"#
- Wait at least 24 hours after mailing (first scan may not post instantly)
- Confirm you entered the number correctly
- If you mailed through an online provider, confirm the piece has been deposited and accepted
Stuck on "In Transit" for a long time#
- A few days can be normal.
- If there is no movement for about a week, consider contacting USPS or initiating a missing mail search.
"Delivered" but the recipient says they didn't receive it#
- Someone else at the address may have signed (family member, receptionist, building staff).
- If you purchased ERR, retrieve the signature documentation to identify the signer.
How long are tracking records kept?#
USPS retention windows vary by product and service level, but Certified Mail tracking history is commonly available online for up to 2 years.
Do not rely on being able to retrieve evidence forever:
- save your mailing receipt (PS Form 3800) indefinitely for high-stakes matters
- screenshot/export the tracking history while it's available
- download ERR PDFs as soon as they are available
If you need retention beyond USPS windows, use a system that archives mail records for years.
