What happens if a delivery is missed or fails?

A failed delivery attempt starts a hold clock rather than an immediate return. The carrier records an attempted-delivery scan, leaves a card or an electronic notice, and moves the parcel to a post office, depot or pickup point, where it waits 15 days at USPS and Canada Post, 18 calendar days at Royal Mail, 10 business days at Australia Post, and 7 calendar days at a UPS Access Point.

Inside that window the item can be collected or redelivered. Once the window closes the parcel goes back to the sender, and the return leg is charged to the shipper rather than to the address that missed it.

Where the parcel goes in the hours after a failed stop

A failed stop produces a timed scan and a notice, and the item leaves the address instead of staying on the vehicle for a second try that day. The notice names the reason the parcel was not handed over and lists the options attached to that shipment. USPS uses PS Form 3849, UPS leaves a UPS InfoNotice, Royal Mail leaves a "Something for you" card, and Canada Post leaves a Delivery Notice Card followed by a Final Notice Card after 5 calendar days.

The card is not the only record of the visit. The same event appears in tracking as an attempted-delivery or notice-left line, which is what a reader has to work from when a card blows away or goes to the wrong door. The hold clock runs from the date of that scan and not from the day the card is found, so a card discovered 3 days late has already spent part of the window.

Two fallbacks run before a card is written on most consumer networks. Australia Post leaves the item in an agreed safe place where one exists and takes it to a nearby Post Office where one does not, and Royal Mail tries a neighbour before carding the address. Both outcomes are written on the card, which is why the card usually names a house number or the branch holding the item.

Only one of the five major operators publishes a fixed attempt count

UPS is the only operator among the five covered here that states a number, making up to 3 delivery attempts on regular delivery days before an undeliverable package is returned to the sender (UPS, UPS Delivery Notice). The postal operators publish a notice-and-hold rule instead of an attempt count, because the item leaves the address on the first failure and waits at a counter rather than riding the route again.

That difference decides what doing nothing produces. On a courier network working to an attempt count, silence from the recipient still generates another visit on the next delivery day. On a postal network the parcel is already sitting at a branch or pickup point, so waiting spends the hold period without a second visit ever happening.

USPS writes its rule around the notice rather than the attempt. An item that cannot be delivered gets a notice, and a redelivery happens because somebody asked for one, which is how a package can sit at a Post Office for two weeks with a single attempt scan against it. The status that precedes all of this is out for delivery, and the attempt scan is the line that closes it.

Hold periods run from 7 to 18 days, and most count calendar days

The five operators hold an uncollected item for between 7 and 18 days, and Royal Mail, Canada Post and UPS all count calendar days, so a single weekend consumes 2 of them. USPS is the only one of the five that publishes different hold periods for different products.

"A notice is provided to the addressee for a mailpiece that cannot be delivered. 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), unless the sender specifies fewer days on the piece."

USPS Domestic Mail Manual 508.1.1.7, accessed July 2026.

Canada Post runs the same 15 day period but splits it with a second card, which is the closest thing any of these operators publish to a warning before the return.

"We'll send a Final Notice Card to the addressee if they haven't picked up the item after 5 calendar days." The item is then held "at the post office for 15 calendar days, after which time we'll return it to the sender."

Operator	Notice left	Attempts at the address	Where the item waits	Held for
USPS	PS Form 3849 redelivery notice	No fixed count published, redelivery on request	Local Post Office	15 days, 5 days for Priority Mail Express, 10 days for COD
Canada Post	Delivery Notice Card, Final Notice Card after 5 calendar days	No fixed count published	Nearby post office	15 calendar days
Royal Mail	"Something for you" card	Neighbour first, then carded, no fixed count published	Customer Service Point, Royal Mail shop or Post Office branch	18 calendar days
Australia Post	Card, email or SMS notification	Safe place first, then carded, no fixed count published	Parcel Locker for 2 business days, then a Post Office	10 business days
UPS	UPS InfoNotice	Up to 3	UPS Access Point location	7 calendar days

The shortest windows in that table belong to the fastest and most expensive products, which inverts what most senders expect. A Priority Mail Express item is held 5 days against the 15 days given to ordinary mail, so the parcel a recipient is most likely to be waiting on is the one returned first (USPS, Domestic Mail Manual 508).

Booking a redelivery can need 48 working hours of notice

Royal Mail requires 48 working hours of notice for a redelivery, and the date chosen has to fall inside the 18 calendar days the item is held (Royal Mail, Help with my redelivery). That is the constraint most people miss: a booking made on day 17 for a date on day 20 cannot be honoured, because the item will already be travelling back to the sender.

Every operator here books the redelivery against a reference rather than an address. The card carries a barcode or reference number, and where the card is missing, the shipment's tracking number does the same job on the carrier's own site. A seller's order page cannot schedule a redelivery, because the seller does not control the item once it is inside the delivery network.

A redelivery repeats the original stop rather than booking an appointment. It lands somewhere inside the same 10 to 12 hour route window as the first attempt, so a household that was out during the first visit will usually be out during the second unless the address changes or somebody is nominated to receive it. The published delivery hours for each operator set the boundaries of that window.

Collecting in person, and who else is allowed to

Australia Post gives 2 business days at a Parcel Locker before the item moves to a Post Office counter, inside a total of 10 business days.

"You have 10 business days to collect your item before it's returned to sender."

Identification is the gate at every counter. Australia Post accepts one valid photo ID such as a driver licence, passport or government-issued proof-of-age card, or 2 non-photo documents where at least one carries the delivery address (Australia Post, Missed parcel deliveries). UPS asks for a government-issued photo ID at an Access Point, matched against the surname and address on the label.

Collection by somebody else is allowed on most networks, but only through the paperwork. Australia Post carries a collection authorisation section on the waiting-collection card, which the nominated person takes to the counter with their own proof of identity. Without that authorisation the counter refuses the item and the hold period keeps running, which is a common way a perfectly collectable parcel still ends up returned.

When the address was occupied and an attempt was recorded anyway

An attempt scan against an occupied address starts the hold clock like any other, and the 15 or 18 days run from that scan whether or not anybody knocked. Disputing the scan does not pause it, so the first move is to secure the parcel and the second is to raise the attempt.

Access rather than absence. A gated entrance, a locked lobby, an unanswered intercom, roadworks or a loose dog end a stop the same way an empty house does. The driver has a route to finish and records an inaccessible door as an unsuccessful stop.

Nobody eligible was there to receive it. A signature-required or age-restricted parcel handed to nobody qualifying is a failed attempt rather than a completed one, and an item too large for the receptacle produces the same outcome at a mailbox-only delivery point.

The card went elsewhere. Cards get posted to a neighbouring door, dropped into communal mailboxes, or blocked by a full letterbox. The tracking line is the reliable record, and the scan time can be checked against the operator's own route window before anything is escalated.

The stop was never worked. Where no card exists and the scan time falls outside any plausible route hour, the attempt is worth challenging with the carrier in writing, quoting the timestamp. Raising it through the sender is often faster on marketplace orders, because the contract for carriage sits between the sender and the carrier.

Signature and age-restricted items fail more often and are held on shorter terms

An item carrying a signature requirement cannot fall back to a safe place, and the strictest tier needs a recipient aged at least 21 holding government-issued photo ID. UPS Adult Signature Required is the clearest case: the package cannot be released to a doorstep on a later attempt, and alcohol shipments moving under it call for a driver licence, passport, military ID or permanent resident card proving age at the door.

A signature requirement also shortens the window that follows a failure. USPS holds Priority Mail Express for 5 days and COD items for 10 days rather than the standard 15, and both usually travel with a signature requirement, so the parcels least likely to be handed over at the first attempt are the ones with the least time to be rescued.

Two adjustments remove most of these failures before they happen. Redirecting the shipment to a staffed pickup point or locker at the time of ordering replaces an 11 hour residential window with a counter open on published hours, and nominating an eligible adult in advance covers the age-restricted case that a safe place never can.

What happens when the hold expires, and who pays for the return

The sender pays for the return on the operators that publish a rule, and the item travels back on the service it was sent with. Canada Post states that all associated return-to-sender shipping fees are the shipper's responsibility (Canada Post, Return to Sender). That cost is why many retailers deduct return shipping from a refund on an uncollected order while refunding a genuine delivery failure in full.

A returned parcel is not a lost parcel. It re-enters the network with a leg still to run and its history continues under the original number, showing a return or redirect scan rather than going quiet. The return leg takes roughly as long as the outbound leg took, because it uses the same service.

The return itself only fails when the sender cannot be identified or will not take the item back. USPS treats undeliverable articles worth 25 USD or more as dead mail, and dead parcels are opened at the Mail Recovery Center so that a name and address can be found and the item delivered or returned (USPS, Domestic Mail Manual 507). That is the end of the line for a parcel nobody claims, and it is reached weeks after the missed delivery rather than days.

Responsibility changes hands at the moment the item is returned. Until then the carrier can still redeliver it or release it at a counter, and after that only the seller can reship or refund, because the seller is holding the goods.

A failed attempt is not the same as a lost, held or delayed parcel

Five tracking outcomes get read as the same event, and only 2 of them start a hold clock. An attempted-delivery scan means the parcel reached the address and came back with the driver, which is a different situation from an item still moving, an item handed to a neighbour and already off the network, or an item on its way back to the shipper.

Tracking line	What it means	Who holds the parcel	What to do
Delivery attempted, notice left	The stop was made and the item was not handed over	Carrier depot or pickup point	Book a redelivery or collect before the hold expires
Available for pickup, awaiting collection	Already sitting at a counter or locker	Post office, Access Point or locker	Collect with ID, 7 to 18 days are running
Delivered to neighbour or safe place	Handed over at a different point on the same visit	The neighbour or the safe place	Read the card for the house number or location
In transit	Still moving, no attempt has been made	Carrier network	Nothing yet, no hold period is running
Returned to sender	The hold expired, or the item was refused	The shipper, once it arrives back	Contact the seller rather than the carrier

The nearest neighbour to a failed attempt is the in transit line, which carries no hold period and needs no action. Reading the full scan history rather than the last line separates the two, because an attempt scan is always followed by a movement scan towards a branch, depot or pickup point.

For an item already carded, the sequence is short: read the notice for the branch and the reference, count the operator's hold period from the date of the attempt scan, and either collect with ID or book the redelivery well inside that window rather than on its final day.
