If Richmond is a Customs location, it may be traveling but is no longer being scanned.
I find that a lot of parcels that come from the US to us here in Canada disappear at the border. If you call Customs, they'll tell you Canada Post has it, if you call Canada Post (or check their site) it will say Customs has it. Then one day it will just turn up in the mailbox. Which has got to be annoying for parcels sent Signature required (which has happened!)

The other thing that happens (I have a parcel in this "black hole" at the moment - My parcel went from California, to Michigan to..... I have no idea at this point, but I'm in Alberta which is considerably closer to California than it is to Michigan.) - A package will often be carried by one carrier until it hits the border, then it will change carriers to make it the rest of the way. When it crosses the border, either the "foreign" arm of the same company, or the new shipping company will often change the shipping number. Which means effectively that the parcel you're tracking stopped in Richmond and the parcel that will arrive at the destination won't be trackable (by you) because no one provided the new number. It's a terrible system, and DH (who used to work for Loomis / DHL) couldn't figure out why they did it, but they all do.

and they wonder why they are going broke!! their routing system always confounds me. it makes no sense at all. But "big" business never did to me.

I just tracked my package mailed last Thursday from Florida to Arkansas and it has been to Memphis and then to NC and then back to Memphis with no delivery date posted. You'd think it was going into outer space! What kind of service is that? We have even had things come to our post office here and then be sent back to whereever for no reason! what??? I don't even think priority or first class makes any difference! It's a shame!

I just had a look on USPS tracking service: nothing happened, the package didn't move.... This reminds me of my search after a package from earlier this year: at least after some weeks it was detected in Cinncinati!!!! No one knows why a parcel sent to San Mateo was going to Cinncinati..... And I wonder where this package will be detected: I made an inquiry request yesterday!!!
But I'm not very amused to this kind of transportation if there is each time I send a parcel such confusion......

ha, ha. just had to say the postman dropped off a large box this morning and ran. I went out to get it and it looked like Santa had sat on it!!!! Luckily it only had a soft slinky throw/blanket in it!!!

I am still waiting word from our local post office. It seems our mail carrier delivered my packages to someone else.
But were supposedly delivered to me on Dec 9 and Dec 16th. I don't have either one.

So today I am going to go back in and ask where they are!!

Christmas rush is a lame excuse......They seem to get my bills in my mailbox.........LOL

USPS maybe in the same situation as UPS. I have had a package sitting in Mesquite, TX....driving distance from me, for over 10 days. Information sent to me says the package was delayed due to bad weather....it has been in the mid 70's and above freezing for over a week. Explanation, finally, UPS hub has 100's of tractor trailers side by side that have not been opened and packages processed. UPS said your package is in one of them, so you can't pick it up...just keep checking the website. Yeah, Yeah. Lots of folks will not get their gifts on Christmas.

Well we found out about the missing packages. They were stolen!! The Sheriff has someone in custody. I filed a report and gave the Sheriff copies of my invoices. I don't hold out much hope of ever seeing my items though.

That sounds very bad, I am so sorry for you.... But I believe the same thing happened to our package...It was a very big parcel nearly 10kilograms....
