Tracking not updated on an ACBuy parcel: the gap before a UK number appears
Some parcels leave China under one number and only show their UK tracking days later. ACBuy’s article sets two numbers: 3 to 7 days for the final tracking to appear, and more than 7 days before its stated contact condition, subject to flight and customs exceptions.
Illustrative status sequence: the example days are not a delivery forecast or a claim deadline.

- after day 7still nothing: contact support
Two kinds of tracking number
ACBuy’s Tracking Not Updated article starts by explaining why a tracking page can look empty. Depending on the logistics route, some parcels only generate or update their real tracking number after arriving at the logistics warehouse in China. Others only show the final tracking number once they reach the destination country.
In practice your parcel page can show a first number, or a run of Chinese handover entries, and then nothing for days. A missing final number can be a relabelling gap; the empty field alone does not establish the parcel’s location or rule out a problem.
Where the final number shows up
ACBuy points to one place: the Logistic Tracking section of the Parcel Detail page, opened from the Parcel page of your account. That is where the destination reference is recorded. A number can exist before a carrier physically receives the parcel, so check its actual scans.
Two habits help. Check there rather than in an old shipping email, because the number can change after re-labelling. And once a UK number appears, use it on the carrier’s own website as well: the carrier usually records scans before the agent’s page picks them up.
Keep a note of every number the page has shown, with the date you first saw it. If the parcel later needs a case, support will want to know which number was live when, and a re-labelled parcel can carry two or three over its life: one from the warehouse handover, one for the international leg and one for the UK delivery. The last of these is the one Royal Mail, the local post office or UPS will recognise.
Day 7, and the two reasons that excuse it
The article gives the normal window plainly: parcels re-labelled in China will normally update the final tracking information in the destination country within 3 to 7 days after shipment. The count starts at shipment, not at the last entry you saw.
The contact rule follows: if the parcel has not been updated for more than 7 days, and the delay is not due to flight scheduling or customs inspection, you can try ACBuy’s online customer service. Those two exceptions matter. A parcel that is waiting for a flight or sitting with customs can go past day 7 without anything being wrong, and support may simply tell you so.
What to send ACBuy support
Keep it short and give them what they need to query the logistics provider: the AP parcel number, the line name, the shipment date shown on the parcel page, the last entry on the tracking page and any first-leg tracking number. A screenshot of the empty Logistic Tracking section saves a round of questions.
Support keeps Beijing office hours (09:00 until 18:00 there), so a reply follows the rhythm of a working day in China rather than yours. One complete message gets a useful answer sooner than three short ones sent as the worry grows.
Which UK lines are re-labelled
ACBuy does not say. Its article speaks of “some” routes and “parcels that are re-labeled in China” without naming them, and the line notes in the estimator do not mention re-labelling either. What the notes do say is who delivers: Royal Mail on the two duty-free Royal Mail lines, the local post on the three China Post lines, UPS on UPS(HK)-5000.
The 3-to-7-day window applies to parcels re-labelled in China, not automatically to every line with a missing number. If yours shows a 1Z number from the start, you are on UPS and this article is not your concern; the Warehouse Scan page is.
A Chinese logistics reference and an empty carrier field are clues, not confirmation. Ask ACBuy whether this parcel is re-labelled and which number to use; do not ignore a carrier request while waiting.
