India Post Offices in Ariyalur, Tamil Nadu

For a district as farm-and-cement focused as Ariyalur, the postal reach goes a lot further than the main town. India Post keeps 226 offices here, organised under 38 PIN codes mostly in the 621 series. The district does not run its own head post office; instead the sub and branch offices route their mail up through the Lalgudi head office. Below that connection sit 30 sub post offices and 196 branch offices, so roughly nine in ten counters are the small village branch type that bring the post right out to the fields and hamlets.

That rural weighting is the defining feature. Look past the few town addresses and you find post offices in Ariyalur tucked into villages like Anaikudam, Alathiyur, Cholamadevi and Elaiyur, each pulling its mail through a branch counter. The four taluks share the work fairly evenly, with Udayarpalayam and Ariyalur holding the larger numbers and Sendurai and Andimadam covering the rest. Andimadam (621801) and Ambapur (621701) are among the named towns with their own codes, while the main 621 series runs from 621651 outward across the taluks. For the area-wise breakdown, the Udayarpalayam taluka post offices page and the Ariyalur area directory list every office, which helps when two villages have similar names.

One thing worth planning around: the village branch offices tend to keep short single-shift hours, so post early in the day rather than turning up late. Sub offices in the bigger towns stay open longer and handle more counter work, and their timings are not identical, so a quick check before a long journey is sensible. For Speed Post and parcels especially, an early drop gives your article the best chance of joining the same day’s clearance toward the Lalgudi routing point. Senders who post in bulk usually find the larger town counters the smoother option.

To pin down a code for a village not named above, the PIN code finder is the fast way, and the Speed Post calculator will price a packet before you queue.
