I was just wondering what happens if a book that was sent with PBS delivery confirmation (and is shown as delivered,) is not marked received? Does the system eventually look at the DC somehow and sees it's been delivered?

From help:

USPS sometimes scans a package as "Delivered" when it reaches the requestor's local Post office

• there may be a few days' delay before the package reaches the destination address.
• If your package has been scanned as Delivered and has not been marked received a week later, please contact the requestor first using the PM button on the transaction.  If she or he does not respond to your PM within 3 or 4 days, please contact us, and we will look into it.

PBS will mark a book as delivered in certain circumstances.  Such as suspended accounts.  Or folks who do not respond to contact.  But it is often still in the post office.  If you are the receiver, you can also contact your local PO with the DC number.  That may cause the PO to look around for your book.  As media mail does get very low priority, it is often set aside on heavy mail days.

If PBS DC is used, once the book is scanned  anywhere along the way, or at "delivery"  you will receive your credit.  DC is not foolproof. The reasons Emily mentioned above are a few for it not being mark received. Another is that the book was actually delivered - but to the wrong address.  DC just means it was delivered somewhere.
 

I had the same question (thanks), but have another regarding same. Does the person who has not marked the book received get the automated PBS email asking whether the book has been received? (I got 2 of those this am). Mine shows delivered on the 16th, but if they get the PBS email, I don't want to "pester" them...

UPDATE:  LOL, they might have...it was just marked received! as I typed my post!

The system will send out automated reminders starting a few days before it's going to go lost, maybe even a week.

So what happens if they don't mark it received? It doesn't revert back to an undelivered book does it? This person actually has more than than the 200 book limit on her WL. (I wrote about it a while back on the CMT board.) She now has even more books on her WL than when I made the original thread. I'm wondering if the book is not marked received whether that gives her another slot on the WL somehow.

If they don't mark the book received, no matter how it is sent, it will go lost and they get their credit back.

If you sent it with DC and it was scanned along the way, or if you used PBS postage with DC, then you also "keep" the credit (that is the "credit insurance" that is what you pay for when you use those services). So, in effect, the refunded credit for the lost book comes out of PBS's pocket instead of yours.

I always PM someone before a book I sent them goes lost ... I wait until 3 or 4 days before the "lost" deadline .... and of the 4 books that I have had to do this with, all 4 had been received and just not marked "received" for various reasons.

I also PM because I don't receive any PBS emails ... I have my email set to filter them automatically so I never see them. I log in every day to look at my account.  I assume that other people may do this also, so I don't rely on PBS auto emails.

But it is also possible that your receiver is on vacation, for example, and has not had a chance to collect the mail, even though the DC says it is delivered. Or, as other people have said, it is not unknown for a book to be "delivered" right to the wrong address or not at all, even if it is scanned.

So, if you do PM, don't assume that the book has actually been received, even if it was scanned that way.

If the book that she does not mark "received" was a Wish List book, then yes, it will go back onto her Wish List when it goes "lost". Even if that bumps her over the 200 book limit.

If someone has a high percentage of lost books, it will trigger the system to flag the account for review.
