Frequently Asked Questions
What happens if I use a Non-Delivery Pincode?
If you address a courier to a Non-Delivery post office (often used just for sorting or administration), your package will be delayed. It will have to be manually rerouted to the correct local delivery branch.
How many Post Offices are there in Chennai?
Chennai has over 300 post offices spread across its various zones and neighborhoods. However, not all of them handle public mail delivery, which is why verifying the specific PIN code for your area is crucial before shipping.
What is the difference between a Sub Office and a Head Office?
An HO (Head Office) is the main administrative branch for a large region. An SO (Sub-Office) operates under the HO and handles the actual day-to-day mail delivery for specific local neighborhoods.
