And the replacement (different lot number) working. Now I know to keep a file of my box flaps.

With you, but living in a rural location in my benighted states of America. Same deal; repeated failures (it seems Dexcom’s end-of-2024 batch might have been a little defective, I’ve been using for years before this), PO BOX plus no cell coverage to speak of and I don’t use Clarity (I don’t want to share my data without payment.)
I suspect the apps don’t get the serial numbers; xDrip+ will tell me everything else (including the blueteeth ID which is globally unique) but doesn’t seem to know the serial number, JamOrHam’s Dexcom supporter might know but not me!
I just stack the boxes (with the “inserter”) in a corner and take the last one off the stack when they fail. Not very neat but I have a lot of space. I advise writing the pairing code (the four digit number) on the sensor after you have removed the previous one from your other arm. Difficult I admit; I get my wife to do it and I can normally make out enough digits to find the right inserter and then the 21 code. I haven’t been 21 for a while; ■■■■■■ me off every time I have to do that.
Take a picture of the inserter not the box because the inserter has the pairing code so you can match up and the box does not.
Here in the US we have various tricks with the guys in the Post Office; I’m somewhat concerned that my approaches will get cancelled in the very near future but I can at present generate an address that works with FedEx/UPS/DHL and, indeed, my governments postal service.
Nevertheless expect the expected; I’ve been working (for around 10 years now) to make every single corporate entity with whom I communicate understand that if they send something to my street address using the postal service it can’t possibly get here. I keep hitting them but they don’t get any better.
It’s a chore.

Yep, a chore, but chores can just be learned. I started on Dexcom in early January and was lucky to have no failures til June.
I’d think you only need the pairing code for the current sensor- my Dexcom app does store that and the serial number for the active sensor.
On my iPhone Dexcom creates a new Bluetooth pairing each time. I had like 15 and nothing to indicate which one was active. On my last change I deleted them all. It hardly matters, but less clutter better.
And also I lived 10 years at a rural address in north central Arizona. I did have a street address and I could get FedEx, UPS, but postal mail went to a community box around the corner. I have to credit hard working people in the small post office, as they had to sort mail sent to a street address to my assigned box number.
I thought it was federal law that every residence had a physical street address- that’s not true in Canada for rural residences. The gravel road my property is on has no name nor are there addresses, just a land location based on township/range/section designation. I cannot get any parcel deliveries sent here, it’s like being off the map.

For Dexcom’s reporting that isn’t enough although I did notice when I reported my latest failure that the on-line form does seem like it might accept the pairing code now. There are only 10,000 different pairing codes so when Dexcom have 100 failures to deal with at one time they will almost certainly have a duplicate:
At least when I was at [high] school the math master got great mileage out of that one but we were a class of 30 pupils.
Yep. Apparently neither on Android nor Apple can apps delete bluetooth pairings themselves though, curiously, an app is required to pair to a particular G7; I would expect that app to get a privilege to delete the pairing. Go figure, must be some money hiding somewhere.
It’s not clear that the clutter does not matter. It would not surprise me if something started breaking in either iOS or Android when the number of bluetooth pairings spiralled.
Well, no, but that was not my point; I do live in a structure formally approved by my local building codes department and to which a street number was given. The USPS does not deliver here full stop. It is true that I might be able to erect a mailbox more than a mile down the road, where the county maintenance ends and I might then be able to persuade the USPS to extend the current rural carrier route that serves a few residences round here out to that particular point at the end of the maintained road (but I doubt it).
Strangely none of the other people who live down this road have done that. The Grants Pass Courier has a drop point for one customer but no one steals newspapers these days.
No difference in the US. It’s the same system; TRS and tax lot here. I don’t know how CA does taxes but I can believe given the enormous area that most of the time TRS is enough; a section is a square mile, 640 acers for those who don’t know. Where I live a tax lot is what is used; the sections have tax lots even though some tax lots span many, many sections (think forest land owners; the corporations and the old families.)
There’s no general rule. The west coast of the US never had federal mail delivery. PO Boxes are the connection to the government (where the tax demands go). UPS/FedEx depend on a street address which requires, in effect, a locally (county level) approved building (“structure”), DHL just drops stuff off at Portland round here (Oregon).

Sorry for hijacking the topic somewhat on this! @jbowler I respect you’ve done the math or read the same thing on-line I did that 10,000 is the number. But I’m interested in a refresher course I’ve forgotten much of what school taught about combinations and permutations. I looked up the formulas and did some figuring with them. Ref the codes, are you using 10 numbers (for activation) or 26 letters (the resulting BT code) and permuted or combined? I couldn’t get the formula’s to come up with 10,000 no matter how I figured it. 10 numerals permuted 4 at a time was 5040, combined was 210; 26 letter permuted 4 at a time was 358,400, combined was 14,950. What part am I missing?
BTW, the HOA where my little WV cabin is located is going thru the same thing ref addresses. WV issues E911 required addresses and mandates use of the USPS approved address signs for emergency responder (Sheriff, ambulance, fire department) use to find a residence, but USPS doesn’t deliver to homes (go figure; FedEx, UPS, and DHL do). Instead USPS will deliver to a centralized set of mailboxes at the HOA or the USPS location in town. The community (aka my wife) researched with USPS, arranged purchase of (USPS approved box sets), and volunteers installed four sets of the boxes on a cement pad. The community has to maintain and label the boxes for USPS use.
The OP said this:
And the context is reporting a failed sensor to Dexcom. I write the pairing code on every sensor after removing the previous one from my arm.
So that’s four decimal digits hence 10,000. Now they might choose to accept the pairing code anyway if they are going to ask for a sensor return because then it doesn’t matter. The problem they seem to be trying to solve is people submitting fraudulent replacement requests; the serial number is sufficient to make that almost impossible because they know exactly when the sensor with that serial number was manufactured. That doesn’t work with the pairing code, they will get a match within the use-by time-frame most of the time.
