The General Post Office, Mumbai is the central post office of the city of Mumbai, India. The post-office handles most of the city's inbound and outbound mail and parcels. Situated in the vicinity of Victoria Terminus, this outstanding structure is a paradigm of Indo-Saracenic architecture.
As the chief post office of the city, the post office handles huge volumes of mail and passes them on to other post offices in the city. The GPO has the Postal Index Number (PIN) 400 001. Due to its vicinity to Victoria Terminus, it is ideally situated to dispatch and receive mail to and from other cities in India. It also controls the smaller post offices in Mumbai, issues stamps, and prints new inland letterheads and postcards. It also has a philately section for enthusiasts.
This Particular Post Box in front of the GPO reminded me of the era when no one ever heard of E-Mail/Internet. When Hand written mails were the only way to communicate.
