For yellow label packets during the June exam series, there will be daily scheduled collections if you have timetabled exams on three or more days during any week in the exam series.
Parcelforce will have contacted you before the start of the series to arrange this.
If you have two or fewer timetabled exam days every week during the June exam series (and during the November and January series regardless of the number of days with exams) then you will need to contact the Parcelforce Worldwide exams helpdesk before the exam series so that ad hoc collections can be arranged.
Further details are available on the DfE website.
At the time of collection make sure the Parcelforce driver signs a printed copy of the despatch log to confirm collection of the number of packets listed and the date and time of the collection.
For white label packets, you will need to contact your chosen courier/despatch company to arrange collections.
