At the Post Office

Post offices provide services for mailing letters, aerograms (single sheets folded over and addressed), and postcards. Delivery time is unpredictable and usually takes longer than one might expect. It is best not to send packages through the postal service. Use a private courier service instead. DHL is a popular international courier service, while TCS is a popular domestic courier service. Some TCS offices are open 24 hours. In Pakistani English, packages are called 'parcels;' mailboxes are called 'postboxes.'
