Questions people ask
What carrier is a tracking number starting with GV?
Royal Mail. A Royal Mail tracked number issued through a China forwarder for UK-bound parcels. Royal Mail's site shows nothing until the parcel reaches its Heathrow hub. The number is created in China days before that.
Where do I track it?
Royal Mail once it has scanned. Before that, the China leg is only visible through the agent's own logistics feed, which the RepTools tracker merges in.
Is a GV…GB number Royal Mail or a Chinese courier?
Both, in sequence: the number is a Royal Mail tracked number created through a China forwarder, so Royal Mail delivers it but shows nothing until the parcel reaches a UK hub. Royal Mail is also the carrier most likely to deliver on a Saturday in our data, 61 of 347 deliveries.
Why does my tracking number show nothing?
Because the number was created before the parcel left China. Local carriers like Canada Post, USPS and Royal Mail only scan once the parcel lands in your country, usually 4 to 10 days after your agent ships. The RepTools tracker fills that gap with the agent's own China-side scans.
