What happens to a USPS package that needs a signature when nobody is home?

The delivery rules

“The following conditions also apply to the delivery of Priority Mail Express, Registered Mail, Certified Mail, mail insured for more than $500.00, Adult Signature, or COD”

DMM 508.1.1.7 extends those conditions to mail with a return receipt or restricted delivery, and sets two that matter here:

“a mailpiece may not be opened or given to the recipient before the recipient signs and legibly prints his or her name on the applicable form or label”

“If the piece is not called for or redelivery is not requested, the piece is returned to the sender after 15 days (5 days for Priority Mail Express, 10 days for COD)”

The return clock runs “unless the sender specifies fewer days on the piece” (DMM 508.1.1.7). Signature Confirmation isn't named in that list, and we found no separate hold period for it in the DMM sections we read, so we don't give it a day count; the notice the carrier leaves says where the package is waiting.

“A carrier release endorsement may be used on only: ... Parcels which do not require a signature”

That is DMM 508.1.2: the “leave if no response” endorsement can't go on a package that needs a signature, or on an insured one.

What the buyer can do with the notice

• Schedule a redelivery online with the tracking number or the barcode on the back of PS Form 3849. “For same-day Redelivery, make sure your request is submitted by 2 AM CST Monday-Saturday or your Redelivery will be scheduled for the next day.” (USPS Redelivery page)
• Pick it up at the Post Office written on the notice: “Or you can send someone else to serve as your representative.” (USPS Redelivery page)
• Use a Smart Parcel Locker, if the box on the front of the notice is checked (USPS Redelivery page).
• Send it back: “If you don't want to receive the package, USPS will send it back to the shipper with the endorsement "Return to Sender."” (USPS Redelivery page)

Whoever collects it still has to meet the service's rules: for Adult Signature, someone 21 or older with acceptable ID (DMM 503.8.1.1); for Restricted Delivery, only the addressee or an agent authorized in writing (DMM 508.1.1.8).

“If the specific individual is not 21 years of age or older, the mailpiece will be returned to sender.”

Priority Mail Express is on a shorter clock

“A reminder notice is left on the third day after the attempted delivery. A second delivery is attempted only upon customer request.”

And it goes back to you after 5 days instead of 15 (DMM 508.1.1.7). An on-time delivery attempt counts as service for the money-back guarantee: DMM 604.9.5.1 refunds an item not delivered, not attempted, or not made available by the scheduled date and time (when the refund applies).

What you can do as the seller

• When tracking shows a notice left, send the buyer the redelivery options above; the clock is already running.
• Want it back sooner? Print fewer days on the package before you mail it, which DMM 508.1.1.7 allows.
• For a buyer who is rarely home, ship Hold For Pickup to their Post Office instead; it costs nothing extra.
• Already in transit? Package Intercept can redirect it to a Post Office as Hold For Pickup for $19.45, if USPS catches it.
• Use signature services only where you need them (your options); each one adds a step for the buyer.

If it comes back: the fee

“For undeliverable Certified Mail and Signature Confirmation extra service fees, when the mailpiece has received an event scan that indicates an attempted delivery (e.g., UAA, Refused, etc.).”

That's DMM 604.9.2.4's list of refunds USPS won't make: once the tracking shows an attempted delivery, refused or undeliverable scan, the Certified Mail or Signature Confirmation fee was earned. A fee is refundable only when USPS didn't provide the service at all, applied for between day 30 and day 60 (refund rules).

Getting the package back costs no extra postage on Ground Advantage or Priority Mail. DMM 507.1.1 counts unclaimed mail as undeliverable, and DMM 507 Exhibit 1.5.1 returns an unendorsed Ground Advantage, Priority Mail or First-Class Mail piece with the reason attached, at no charge, when the buyer has no change-of-address order on file. For insured pieces, which includes the $100 that comes with those labels: “All insured First-Class Mail, USPS Ground Advantage – Retail, USPS Ground Advantage – Commercial, and Priority Mail pieces are forwarded and returned at no additional charge.” (DMM 507.1.4.5) For Media Mail, see undeliverable or refused Media Mail.
