Address Validation API for India — house-number level, rooftop coordinates | Acuris

🇮🇳 INDIA

Premise-level address validation for India.

India is the hardest addressing market on earth — landmark-first addresses, six locality levels, and a data landscape most global providers gloss over with an interpolated point. We validate Indian addresses down to the house number, with rooftop coordinates, against our own India reference database — built in-house over years, not licensed in. And where we can't confirm a premise, the response says so.

Our own India database. Every response carries an explicit accuracy tier — if it's a PIN-code centroid, we say so.

What an India validation returns

Parsing, standardization, PIN-code and locality validation, and coordinates — with the accuracy tier stated plainly, not implied.

A real response from our India database. Where the house number and street confirm, you get rooftop at full confidence. Where they don't, the accuracy_type drops to street, postcode_centroid or locality_centroid — and says so, rather than dressing an approximation up as a premise.

Why honesty is the feature

Most providers round India up. We don't.

Global address APIs routinely return an interpolated point in India and label it like a verified premise. Published coverage tables state the best attainable level and never the hit rate. Our engine reports what was actually confirmed on each individual address — and what wasn't.

House-number validation, rooftop coordinates

Over 4 million of our 5.78 million Indian address records carry house numbers. A confirmed premise returns rooftop coordinates at full confidence — not an interpolated point along a street line.

Explicit accuracy tiers

Every response states its tier — rooftop, street, postcode_centroid, locality_centroid — with a matching confidence score. Your systems can branch on what was verified instead of guessing.

Our own reference database

Built in-house over years, not licensed from a global map vendor. That means we can fix what you report, on our schedule — and it makes India available for reference-data licensing, not only as an API.

In evaluation ROADMAP

Digital addressing standards

India is standardizing digital addressing (India Post's DIGIPIN initiative). We track these standards closely and plan to return standard digital address codes alongside validated addresses as adoption matures.

Built for how India actually addresses

How Indian addresses are structured

PIN code
Six digits, first digit = postal region. The single most reliable component of an Indian address — and the anchor of our validation.
State / District
28 states and 8 union territories, subdivided into 700+ districts and sub-districts. We verify the full administrative chain.
Locality levels
Indian addresses stack up to six locality levels — colony, sector, block, nagar, layout, phase. Our reference schema models all six explicitly.
Landmarks
"Near the temple", "behind City Mall", "opposite the bus stand" — landmark phrases are first-class citizens in Indian addressing. We parse them out rather than choking on them.
Building & flat
Building name, wing, floor and flat number, each modelled separately — the difference between a delivery and a call to the customer.
For address-validation providers

India coverage for AV & e-commerce platforms

If your stack covers Europe and North America well but thins out east of Istanbul, we can be your Asia layer — white-label, per-transaction, benchmark before you buy.

Wholesale API

Per-transaction India & Asia coverage

One wholesale API for the markets your current supplier doesn't reach at street level — India, Japan, Korea, Taiwan, Thailand, Vietnam, the Philippines, the Gulf. Priced per transaction, no minimum commitment to start.

Benchmark first

Prove it before you pay for it

Send us your India test set — or use ours — and we return per-row accuracy tiers you can score against your current provider. We sell measurement, so we're happy to be measured.

Reference data

License the India database itself

Because we built our India reference data in-house, we can license it — not just serve it. Bulk reference data for your own stack, structured in line with India's geospatial data guidelines. Rare in this market: most vendors resell someone else's India and cannot sublicense it.

Honest labelling

Your customers see real tiers

Resell India coverage without inheriting inflated accuracy claims. Every response carries the tier that was actually verified — the honesty is contractual, not cosmetic.

Straight answer

India is not uniformly premise-level and we won't pretend otherwise: coverage is deepest in urban and metro areas, and a rural address may resolve to street, PIN or locality precision. The difference is that our response tells you which one you got, on every single row. If a provider quotes near-perfect premise accuracy across all of India, ask them for their per-row accuracy tier — and for their hit rate, not their ceiling.

A number, with its method. We sampled 400 addresses at random from our own India reference data and validated them through the live API. With the house number supplied: 66.2% returned rooftop, 31.8% street, 2.0% postcode centroid, and the street component confirmed on 97.5%. Drop the house number from the same 400 and rooftop falls to 0.5%. Note what this measures — the matcher against addresses we hold, not coverage of every address in India; your own file will contain addresses nobody has. That is exactly why we hand you a per-row tier instead of a headline percentage.

Straight answers

India address validation, answered

What accuracy can I expect for India today? +
Premise-level where the address exists in our data — honestly labelled everywhere else. Over 4 million of our 5.78 million Indian records carry house numbers, so a well-formed urban address typically confirms to rooftop with full confidence. Coverage thins outside metros; there the response returns street, postcode_centroid or locality_centroid with a matching confidence score. It never dresses a centroid up as a rooftop.
Whose data is behind this? +
Ours. The India reference database was built in-house over several years — it is not a resold global map-vendor feed. Practically, that means two things: corrections you report get fixed on our schedule rather than a supplier's, and India is available for reference-data licensing, not only as an API.
Can I license Indian reference data from you? +
Yes — this is one of the few markets where that's possible. Because we own our India data outright, we can license the reference database itself for your own stack, structured in line with India's geospatial data guidelines. Most vendors serve India from a licensed global feed and cannot sublicense it. Tell us your requirement.
Do you support DIGIPIN? +
It's on our roadmap. India Post's DIGIPIN gives every location a short digital address code, and we intend to return standard codes alongside validated addresses as national adoption matures. We deliberately do not claim support before it ships.
I run an address-validation service. Can I resell your India coverage? +
Yes — that's exactly the model. White-label wholesale, per-transaction pricing, and a benchmark phase first so you know precisely what you're reselling. The same applies to our wider Asia coverage. Start the conversation.

Premise-level India, measured on every row

House-number validation with rooftop coordinates, from our own India database. Accuracy tiers that never lie to you — that's the product.

India address validation runs against Acuris's own India reference database (5,779,431 records, 4,012,423 carrying house numbers), built in-house. Coverage and attainable accuracy vary by region; the accuracy tier returned with each response states what was verified for that address. DIGIPIN is an initiative of India Post. Example responses are illustrative. Accuracy tiers describe what was verified for each individual response. Verified August 2026.
