India Pincode Lookup API Reference

Overview

A pincode lookup API built from the All India Pincode Directory published by the Department of Posts, Government of India. One call returns the full picture for a PIN code: district and state with its ISO 3166-2:IN code, the India Post circle, region and division, a coordinate taken as the median of its offices, and every post office under the PIN marked as head, sub or branch office with its delivery status and own coordinates. Reverse lookups find PIN codes by post office name, district or state. The coordinates and the post office list are on paid plans, as is nearby=true, which lists the PIN codes within a radius of up to 50 km, nearest first.

Endpoint

One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.

GEThttps://api.apiverve.com/v1/indiapincode

1
2

curl "https://api.apiverve.com/v1/indiapincode?pincode=110001&office=Connaught%20Place&district=Pune&state=Maharashtra&nearby=true&radius=10&limit=10" \
  -H "x-api-key: your_api_key_here"

const res = await fetch('https://api.apiverve.com/v1/indiapincode?pincode=110001&office=Connaught%20Place&district=Pune&state=Maharashtra&nearby=true&radius=10&limit=10', {
  headers: { 'x-api-key': 'your_api_key_here' },
});

if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);

const { data } = await res.json();
console.log(data);

import requests

res = requests.get(
    "https://api.apiverve.com/v1/indiapincode?pincode=110001&office=Connaught%20Place&district=Pune&state=Maharashtra&nearby=true&radius=10&limit=10",
    headers={"x-api-key": "your_api_key_here"},
    timeout=15,
)
res.raise_for_status()

print(res.json()["data"])

package main

import (
	"fmt"
	"io"
	"net/http"
)

func main() {
	req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/indiapincode?pincode=110001&office=Connaught%20Place&district=Pune&state=Maharashtra&nearby=true&radius=10&limit=10", nil)
	req.Header.Set("x-api-key", "your_api_key_here")

	res, err := http.DefaultClient.Do(req)
	if err != nil {
		panic(err)
	}
	defer res.Body.Close()

	out, _ := io.ReadAll(res.Body)
	fmt.Println(string(out))
}

Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.

Authentication

Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.

401 is the only auth verdict

A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.

Parameters

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them.

Parameter	Type	Description
`pincode`Optional	string	Six-digit PIN code
`office`Optional	string	Post office name or part of it length 0–100
`district`Optional	string	District name length 0–80
`state`Optional	string	State or union territory name length 0–80
`nearby`OptionalPremium	boolean	With pincode, include the PIN codes within radius km
`radius`Optional	number	Radius in km for nearby (1-50) default 10 · range 1–50
`limit`Optional	integer	Maximum PIN codes to return for searches (1-50) default 10 · range 1–50

Response

Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.

Status	Meaning	What to do
`400`	Input was rejected	Read `error`; it names the parameter.
`401`	Key missing or invalid	Check the header name and the key value.
`403`	Key valid, but not permitted	A key restriction or IP allow-list; see key scoping.
`429`	Rate limited, or out of credits	Read `error` to tell them apart; see rate limits.

Use cases

Checkout Address Autofill: Fill district and state as soon as a shopper types a 6-digit PIN code, and reject PIN codes that do not exist.
Delivery Serviceability: Check whether a PIN code has a delivery post office and list nearby PIN codes for courier zone planning.
Address Cleaning: Standardise district and state names and attach ISO state codes to customer records.
Store and Agent Locators: Find the PIN codes around a branch to define its catchment area.
