as it's part of the "premium" price you pay to mail a chip or two. On several occasions I have had need to use the service. Go online, use the tracking number printed on your post office receipt, and they have a report on where your package went. The one time I had a major problem is when a temporary Christmas Assistant apparently inputted my home address as the destination. This somehow is bar-coded onto the sticker affixed to the package. The poor chip kept getting sent to the Santa Clarita SCF, then back again as the address on the envelope clearly indicated a town in Texas, then back to Santa Clarita, etc., etc. John C. Fremont, Daniel Boone or some other expert USPS Tracker finally figgered it out, pardner, but it took a couple of weeks! (Think someone down the line had to paste a new sticker onto the package but that takes permission of the Deputy Postmaster or some such.) But, I have to hand it to them, I could get a blow-by-blow description of where the missing chip was at all times.
