Notes on The Five Wounds

What is a dead letter? How India Post handles letters that cannot be delivered

By Manu Vishranti · 28 September 2026

A dead letter is a letter the post can neither deliver nor send back: the address is wrong or unreadable, nobody claims it, or it is refused, and there is no return address to fall back on. In India such letters went to the Dead Letter Office, known since 1959 as the Returned Letter Office, where clerks may open them, but only far enough to find a name.

Where the name comes from

Post offices have always had letters that fit nowhere. Britain set up a Dead Letter Office in London in 1784 for dead and missent letters, and the United States opened its own in 1825. "Dead" never meant lost for good. It meant the letter had stopped moving, and someone would now have to work out where it belonged.

India's Dead Letter Offices

The first Dead Letter Office in India opened at Calcutta in 1854. More followed at Madras, Bombay, Lahore and Agra in 1862, and later at Karachi, Nagpur, Lucknow, Mount Abu and Rangoon. After Independence, offices opened at Amritsar and Hyderabad in 1948.

In 1959 the Dead Letter Offices in India were renamed Returned Letter Offices, or RLOs. The new name said what the work was: not burying letters, but returning them.

How a letter is brought back to life

An undelivered letter first waits at the post office for a set time. If it carries a sender's address, it goes back to the sender. If it does not, it travels to a Returned Letter Office. There the staff have a power no other postal worker has: they may open it. Their work runs in steps: find the addressee, or failing that the sender; take out anything of value; and only then dispose of what is left. The old rule still holds that a clerk reads no more of a letter than is needed to find a name or an address.

In July 1976 a newspaper report counted fifteen such offices in the country. Letters were sorted within forty eight hours into sections for English, Gujarati, Hindi, Kannada, Malayalam, Tamil, Telugu and Urdu, and read by staff who used long experience and knowledge of their own streets to make sense of a half address. The Madras office alone received about 156 undeliverable articles a day, with more than eighty people at work on them.

What you can do

Write a full return address, with its PIN code, on every envelope and parcel. It is the one line that keeps a letter from going dead.

Dead letters in The Five Wounds

Two of the five novels turn on letters that did not arrive when they should have. In All the Summers at Once, Book Three, a postmaster has spent his life on the other side of the counter:

For forty years Prem Babu made certain that other people’s words arrived. One letter did not, and he is the reason it did not.

And Book Five carries the name itself. In Dead Letter, thirteen months after his uncle dies, "a registered letter arrives, posted before that death and paid for in advance."
