Understanding postal coverage in East District, Sikkim
East District, Sikkim runs 74 India Post offices across 15 PIN codes, anchored by the Gangtok head post office (737101).
Everything in this district works outward from one point: the Gangtok head post office at PIN 737101. It collects, sorts and forwards mail for the wider area, and the smaller offices below it report up the chain to Gangtok rather than acting on their own. That single anchor keeps a fairly scattered hill network tied together.
Altogether there are 74 post offices in East District, spread over 15 PIN codes. Only the Gangtok office is a head post office. Below it sit 12 sub post offices and 61 branch post offices, so the great majority of counters are village-level branches handling day-to-day deliveries. The Gangtok area carries the most offices by a clear margin, with around 40 of them, while the Rongli side and the country around Pakyong fill in the rest.
If you live in or post from this district, the names you will recognise are places like Deorali (737102), Pakyong (737106), Singtam and Rangli Bazar, along with smaller settlements such as Aritar, Chujachen, Linkey and Central Pendam. Those last ones are usually branch offices, and branch offices in the hills tend to keep short working hours. Drop your letters in early in the day so they catch the day’s onward run instead of waiting till morning.
For anything that has to be signed for or sent abroad, the Gangtok and sub office counters handle Registered Post and international EMS, which give you a proper receipt and a number to follow. You can confirm an exact PIN through the Sikkim PIN code finder, check delivery charges on the postage calculator, or browse the rest of the state from the Sikkim post office directory. North District is another district in Sikkim if you need to look further afield. Once your article is booked, track your India Post item with its number anytime.
