What happens if I miss a signature-required delivery?

If nobody is home to sign, the carrier leaves a notice card and takes the parcel back. From there you usually have two choices: schedule a redelivery for a day you will be around, or pick the parcel up from the local post office with photo ID. The parcel is held for a limited window, roughly two weeks, and after that it goes back to the sender.

Can I sign the notice card instead of being home?

Sometimes. In the US, signing the back of the PS Form 3849 and leaving it where the carrier will find it can authorize redelivery, and the carrier will attempt again on the next delivery day. But that only works for ordinary signature services. For services that require the addressee specifically, or an adult signature, a scribble on the card won't do: someone qualifying has to be physically present.

In Canada, the notice card works differently. You generally schedule the redelivery or go pick the item up yourself rather than pre-signing the card and leaving it out. Either way, the card has the item number on it, and that number plus your ID is what the counter clerk needs. Bring the card if you have it, but the tracking number from the card works too if the card got lost.

What do most people get wrong about signature-required parcels?

First, that a missed delivery means the parcel sits on the truck indefinitely. It doesn't: after the attempts and the hold window, it goes back to the sender, and you may end up paying return or re-shipping costs if the sender passes them on. The clock on the hold window starts when the parcel arrives at the post office, not when you get around to reading the card.

Second, that the carrier will leave it at the door if you leave a note asking nicely. For signature-required items, the carrier is not allowed to do that, no matter what the note says: the whole point of the service is that nobody takes the parcel without signing. Third, that any adult in the building can sign. For some services that is true, but adult-signature-required and addressee-only services restrict who can accept, and a roommate or doorman won't qualify.

Can I waive the signature in advance?

For some services, yes: shippers and recipients can authorize release without a signature through the carrier's delivery instructions. But it has to be set up before the attempt, and it changes the service you paid for. If you ordered something signature-required for security, waiving the signature trades that security away for convenience. Decide based on what is in the box, not on how annoying the post office trip is.

One more practical tip: if you know a signature-required parcel is coming and you won't be home, the pickup option is usually faster than waiting for a second attempt. Redelivery puts you back in the carrier's route order, which might be the next day or several days later. Picking it up yourself takes one trip.
