Why can't I see my parcel in the InPost app?

From 17th July, to get help and support with your parcels, get the InPost app or visit inpost.co.uk/help

There are a few reasons why your parcel may not appear in the InPost app.
If you're manually tracking a parcel, first check that you've entered the correct parcel number. This usually starts with "JD", "JJD" or the number "8".
For a parcel to appear automatically in the InPost app, the mobile phone number provided at the retailer's checkout must match the number registered to your InPost account. The retailer must also share that number with us.
At the moment, parcels being returned to retailers don't appear in the InPost app, but we're working on it!
