The Government Parcels overprints were issued to all departments, including Head Office, for use on parcels weighing over 3lb.
Below this weight government parcels were sent by letter post to avoid the 55% of the postage paid accruing to the railway companies, as laid down by parcel-post regulations. Most of the Government Parcels stamps suffered heavy postmarks in use.
