I mailed a bunch of books yesterday morning at the USPO using the PBS DC and not one of them has shown up as a credit yet.  I don't need the credits yet it just seems like they should have been recorded already. 

I have one that I mailed a while ago and it still hasn't shown up in the system.

not all post offices scan the number- it is called delivery confirmation because it is recorded as delivered when it is delivered.

Actually....that is not entirely the case.  If you  hold your mouse over the lil grey ! it is called "quick credit" now.  The DC IS through the USPS so technically they have no excuse not to scan.  That being said, some times my PO scans here, sometimes it doesn't get scanned until the it goes out for delivery, and yes sometimes it never gets scanned.  The idea is your "quick credit" also gives you credit assurance so even if you didn't get it quick, should the requestor not mark it sent you have a recourse with R&R to get your credit, something you don't have using just UPPS DC.

Also getting scanned does not ensure the info gets to PBS in a timely manner.  One book got scanned at my PO, never got scanned at the delivering PO but the details didn't show up until almost 3 days after the book was marked received by the requestor.

I believe that the OP only used PBS DC - not PBS postage. If that is the case - it's not an instant credit. It's always been called "quick credit", it was recently changed it to "instant credit" if you use PBS postage AND DC. In that case, once you print the label and mark it mailed you will get your credit.  Otherwise, it's just like before - credit will be given when the book is scanned and the data is transmitted from the USPS to PBS.

Tammy, they still don't have to scan it. It doesn't matter who you get it from, it is still DELIVERY confirmation and IS NOT required to be scanned at any time except on delivery. If the PO you drop your pkgs off at runs all pkgs thru a machine that scans the DC, then you'll get your quick credit, if not you won't get it until it either runs thru a station that scans all pkgs or it gets deliverd and the carrier scans it. It doesn't matter if you hand it to them or not, since they can refuse to scan it, you may not get your credit until it is delivered. (Except the new "Instant Credit" which is given immediately, but only IF you also purchased your postage thru PBS)

BUT should it get delivered to the wrong house, or go lost, you WILL get your credit, because it is still "Credit Assurance"

Well I've gained 3 credits since I posted this but my # of books in the mail is the same.  So a couple have been scanned. I was just wondering for future reference incase I'm ever out of credits and desperate for those quickies to come through. 

If you are desperate for the credits to come thru immediately, like when a WL comes up, use the print postage feature too, and they are infact INSTANT! They only depend on the scan if they are DC only.
