Delivery time 

Express Post is still available and remains our fastest postal service. But current operating constraints mean we can’t guarantee next-business-day delivery at the moment.

 

We’ll reinstate our next-business-day guarantee as soon as we can.

Letter size and weight guidelines

We classify a letter as an item that:

  • weighs less than 500g
  • is no thicker than 20mm
  • contains flexible items - nothing rigid or inflexible
  • has a rectangular shape
  • is no bigger than a B4 envelope (260mm x 360mm x 20mm)

If your item doesn't fit this criteria, we'd classify it as a parcel. View domestic parcel services.

Sending keys, pens, USBs or CDs?

Never put rigid or inflexible items in a regular paper envelope - even if you think they're small enough.

They could easily be damaged by our machines or torn from the envelope and lost.

Check our mailing boxes, bags and other packaging options to choose packaging to suit.
