The outside of the packet
The outside of a packet is a set of measurable properties. A carrier system reads several of them automatically and stores them, because its pricing and sorting depend on them.

What the outside consists of
This section is a list of properties and what the system does with each. It is descriptive throughout. Nothing here is a recommendation, and the closing section of this card explains why that boundary is drawn hard.
| Property | What the system does with it |
|---|---|
| Weight | Measured on a plate, stored as a number, used to price the service and to check the price paid was correct. |
| Dimensions | Measured by machine on many networks. Volume affects price and affects which sorting stream an item enters. |
| Class of service | Determined by what was purchased. It governs how many scan events the item generates and whether a delivery is signed for. |
| Label or franking type | A printed carrier label, a purchased stamp, a business franking mark or an account label. The system reads it to establish that carriage was paid. |
| Origin marking | Where the item entered, recorded as a facility and often printed on the item as a mark. |
| Handwriting or print | A destination is either handwritten or machine printed. Automatic sorting reads print directly. Handwriting is commonly resolved by a separate process. |
| Barcode or identifier | The machine readable key that ties this physical object to the file described in a parcel entering the postal system. |
| Declared category on paperwork | Where a customs declaration is attached, it carries a stated category and value. Both are claims recorded by the system, not findings made by it. |
Each of those is a record, not an impression
The distinction matters. A person forming an opinion about an object leaves nothing behind. A machine measuring an object writes a row. Weight and dimensions in particular are not judgements, they are numbers captured for billing, and they persist in the file for exactly as long as billing records persist.
The same applies to class of service. It looks like a purchasing choice and it is really a setting on how much record the item generates. A minimally tracked item produces few events. A signed service produces the doorstep event described in signing for a delivery. The property and the record volume are the same decision seen from two sides.
A declared category behaves differently again. It is the only item on the list that is authored rather than measured. Somebody wrote it, the system stored what was written, and the storage of a claim carries no assessment of it. This card notes that and goes no further.
What the outside does not carry
It is worth being concrete about the absences, because readers overestimate them in both directions. There is no market on a parcel. An Awazon market address is an onion address, which is a network location, and it does not appear on a label, on paperwork, or anywhere in a carrier system. Nothing in the postal chain has any concept of it.
There is no account name, no order identifier, no listing title, no vendor handle and no message history. None of those are postal concepts. A carrier network sorts by destination and prices by weight, and its data model has no room for the objects a market cares about.
What the outside does carry is a destination, which came from a form, which came from a person. That single string is the entire bridge between the two worlds, and it is why the delivery address you hand over and typing a delivery address into a form are the two cards most worth reading alongside this one.
Where the packet ends up afterwards
A label has a second life that no operator is responsible for. Once an item is delivered, the outside of it is an object in a home, with a destination printed on it, and it is visible to anyone who is in that home or who sees it leave. That is not a postal observation. It is the subject of the whole people section, and it is the one part of this card where anything is genuinely in your hands.
Photographs are the same story. A label photographed for any reason becomes an image file with an address in it, which is covered in screenshots and photos of the screen. The postal system did not create that copy and cannot delete it.
Why this card stops here
This card describes what is visible and deliberately does not describe how to change it. There is no guidance here on choosing a weight, a class, a label, a route or a declaration, and none will be added. The line between describing what a system records and instructing someone on how to present something to that system is a real line, and this site stays on one side of it.
If you came to this page looking for the other thing, this is the wrong site, and no other card in this section will provide it either.
What changes the answer
4 things change how much this action gives away. None of them takes it to zero, and none of them is a promise.
- Understand that the measured properties are permanentWeight and dimensions are captured for billing and they sit in a billing record. Nothing later in the journey rewrites them. Knowing this is expectation setting rather than mitigation, and it is the honest version of what this card can offer.
- Do not photograph a labelA photograph of a label is a durable copy of a destination held on a device you carry around, frequently backed up automatically. See screenshots and photos of the screen and backups and sync. This is entirely about your own copies and has no effect on any carrier record.
- Remember the destination came from a form you filled inThe string printed on a label was typed somewhere first. The properties of that earlier copy are described in typing a delivery address into a form. The label is the second copy, not the first.
- Treat the delivered packet as an object other people can seeOnce it arrives, the outside is in a room. Who is in that room is the subject of a shared delivery address. This is a household question, not a postal one, and it is the only observer on this card you have any say over.
What this card is not
This card is not advice about how any item should be prepared, marked or described. It is a description of properties a carrier system already measures and stores.
