Do shipping labels get postmarked?

No. The date printed on a shipping label is the date you created the label, not a postmark. Nothing about printing a label early backdates your shipment: the carrier's acceptance scan is the real proof of when the package entered the system. Note up front: LetterAgent labels are Canada-only Xpresspost, and the same applies to them.

What is the date on the label, then?

It is a print date, sometimes called the ship date, and it reflects when you bought the label, not when the carrier received the package. If you print a label on Friday and drop the box off on Monday, the label still says Friday. That date has no legal or evidentiary weight. Carriers know labels get printed ahead of time, which is why tracking shows two separate events: "label created" and "accepted" or "picked up." Only the second one counts as the package entering the mail stream.

What is the actual proof of mailing for a package?

The acceptance scan. When you hand the package to a clerk or the driver scans it at pickup, the carrier's system records the time and location, and that timestamp is the authoritative record. If you drop a parcel in a bin without a scan, the first scan happens later at the sorting facility, which can be hours or a day after you let go of it. For anything where the send date matters, hand it to a person and watch it get scanned, or ask for a receipt at the counter. A label in your printer tray proves you intended to ship; a scan proves you did.

Can printing a label early backdate a shipment?

No, and trying it as a strategy misunderstands how the system works. A label dated Friday on a package first scanned Monday tells anyone who looks that the package sat for the weekend. There is no scenario where the print date overrides the scan record: insurers, marketplaces, and dispute reviewers all use the acceptance scan. If a buyer claims late shipment, "but the label says Friday" will not help you. Ship it when you say you shipped it, and get the scan.

Do postage meters postmark packages?

A postage meter prints an indicia with a date, and that date is the date the postage was printed, subject to the same logic: it is not a postmark either. Metered mail is supposed to be inducted on the printed date, and carriers can treat stale meter dates as a problem, which is one reason meter users redate. But the date on the indicia still does not function as proof of mailing the way a postmark on a stamped letter does. The acceptance scan remains the record that matters for parcels.
