Questions people ask
What carrier is a tracking number starting with SF?
SF Express. SF Express, a Chinese courier used for the China leg on some lines and as an end-to-end courier to a few countries. Scans in Chinese are normal.
Where do I track it?
SF's site or the RepTools tracker.
I got an SF number before I submitted my parcel. What is it?
That is the seller sending your item to the agent's warehouse inside China, not your international parcel. SF Express is a Chinese domestic courier; it only becomes your shipping number on the few lines where SF carries the parcel abroad.
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.
Counts are tracking numbers looked up on rep.tools in the last 45 days, grouped by format, updated 2026-09-05. Carrier attribution comes from the format itself plus the carrier that scanned the parcel. Delivery times are measured from the first carrier scan to the delivery scan.
