What to do
- Contact the sender immediately to confirm the full, correct address (including unit or apartment number).
- For DHL, contact local customer service to supply the missing recipient information.
- If the package is returned, the sender must reship it (USPS requires new postage).
- Double-check the address on future orders.
When to contact the sender or carrier
Act straight away: Canada Post returns packages it cannot verify, and USPS 'Insufficient Address' items are already on their way back to the sender.
