Experian Address Validation (QAS) vs RevAddress — Pricing and API Compared (2026)

Experian’s address product has worn a lot of names. You may know it as QuickAddress Pro (QAS), as QAS Pro On Demand, or by its current branding: the Experian Data Quality (EDQ) Address Validate API. Under the hood it’s the same thing — an enterprise-grade address capture, validation, and enrichment platform that Experian sells as part of its broader Data Quality suite, covering 250+ countries and territories.

If you’re a large enterprise standardizing address data across dozens of markets — with a procurement team, a contract, and a data-governance mandate — Experian is a serious, mature choice. But most US teams evaluating it aren’t that. They’re a developer who needs one country validated to USPS standards, wants to read a price off a page, and doesn’t want to schedule a sales call to get a POST endpoint working.

That’s the gap this post is about. Experian’s model is quote-only and full-suite by design; RevAddress’s model is flat monthly pricing on the USPS v3 REST layer — DPV-confirmed validation, batch processing, and the rest of the USPS stack included, published on a page you can read right now.

The pricing model is the real difference

As of August 2026, Experian does not publish a price for Address Validate / QAS Pro On Demand. Software review sites (Capterra, G2, GetApp) all list it as “pricing not provided — contact vendor,” which is standard for enterprise data-quality software. You engage sales, scope your volume and deployment, and receive a custom quote — typically annual, usually with a commitment, and oriented around Experian’s full platform rather than a single endpoint.

The problem with a quote-based enterprise model isn’t that Experian’s data is bad — it’s excellent. The problem is the shape of the commitment. You buy a platform sized to a global footprint and an annual number, when what your product actually calls is a US address validation endpoint. For a US-centric team, most of that scope is overhead you’re paying to carry.

What that looks like in practice

Because Experian doesn’t publish a flat rate, here’s an honest conditional rather than a fabricated number. Enterprise address-verification contracts commonly land somewhere around $0.02–$0.05 per lookup once you amortize the annual commitment across real volume. If your negotiated rate came in at even $0.02 per US lookup, the math against RevAddress’s real, published flat tiers looks like this:

The $0.02 figure is illustrative — Experian publishes no flat per-lookup rate, and a real quote often carries an annual minimum that makes the effective per-lookup cost higher at low volume, not lower. The point isn’t the exact number; it’s that a volume-tiered enterprise contract scales with your usage while RevAddress stays flat, and RevAddress’s pricing is public on the pricing page with no quote required.

Where Experian genuinely wins

Let’s be fair, because it matters for the decision:

• Experian covers 250+ countries. RevAddress is US-only (it’s a USPS v3 layer). If you validate addresses in the UK, EU, APAC, LATAM, or anywhere outside the US, Experian is built for exactly that and RevAddress is not a substitute.
• Experian is a full data-quality suite. Match-and-merge, deduplication, data cleansing, enrichment, profiling, and governance — if you need a platform for all of your customer data, not just addresses, that’s Experian’s home turf.
• Experian has mature enterprise autocomplete and formatting battle-tested across large-scale checkouts, plus the compliance and support posture (SLAs, dedicated onboarding) that big procurement teams require.

If any of those describe your situation, stop here — Experian is the right tool and you should get a quote. The rest of this post is for teams whose address volume is US-centric, where buying a global data-quality platform is more than the job needs.

For US addresses: what RevAddress does that Experian’s US path doesn’t

The USPS DPV distinction is worth calling out. RevAddress returns Delivery Point Validation codes on every response — Y (confirmed deliverable), N (not deliverable), D (missing secondary/apartment), S (invalid secondary). That tells you exactly why an address failed, which is what you need when you’re debugging why a package bounced. Experian returns its own verification and match codes; useful, but a layer removed from the raw USPS DPV signal.

Code comparison

RevAddress is a straight REST call with an API key header — no SDK required, no contract to reference, no sales engineer to unblock you.

curl -X POST "https://api.revaddress.com/api/address/validate" \
-H "X-API-Key: rv_live_your_key" \
-H "Content-Type: application/json" \
-d '{
  "streetAddress": "1600 Pennsylvania Ave NW",
  "city": "Washington",
  "state": "DC",
  "ZIPCode": "20500"
}'

The response includes the DPV confirmation code, the standardized USPS-formatted address, and ZIP+4 — the things you actually act on:

{
"deliverable": true,
"dpvConfirmation": "Y",
"address": {
  "streetAddress": "1600 PENNSYLVANIA AVE NW",
  "city": "WASHINGTON",
  "state": "DC",
  "ZIPCode": "20500",
  "ZIPPlus4": "0003"
}
}

RevAddress also accepts field-name aliases — street_address, address1, line1, zip_code, zip all resolve — so you don’t get 400 errors for sending snake_case.

Batch validation without a bulk-processing contract

Cleaning a mailing list is where enterprise contracts get awkward — bulk cleanse is often a separate SKU or a professional-services engagement. On RevAddress, batch addresses count against your monthly cap, and cached repeats don’t count at all — so re-running the same list costs nothing the second time.

curl -X POST "https://api.revaddress.com/api/batch/validate" \
-H "X-API-Key: rv_live_your_key" \
-H "Content-Type: application/json" \
-d '{"addresses": [
  {"streetAddress": "1600 Pennsylvania Ave NW", "city": "Washington", "state": "DC"},
  {"streetAddress": "350 Fifth Avenue", "city": "New York", "state": "NY"}
]}'

Each address is validated independently — one bad record never fails the whole batch. And if a full list cleanse is all you need, List Clean does a one-time CSV cleaning for a flat $97 — no contract, no per-record metering.

Migration from Experian (US validation)

If you’re moving your US address validation off Experian — while keeping Experian for international or your broader data-quality suite if you need it:

1. Sign up at revaddress.com/signup — free, 1,000 lookups/mo, no card, no sales call.
2. Swap the endpoint — replace your Experian Search/Format (Address Validate) call with POST /api/address/validate (see above).
3. Map the result — use dpvConfirmation (Y/N/D/S) instead of Experian’s verification/match codes.
4. Move bulk jobs to POST /api/batch/validate — no separate bulk SKU.
5. Prove it with the free key before touching your Experian contract or renewal.
6. Keep Experian for non-US markets or suite features if your product needs them — this isn’t all-or-nothing.

Typical migration time for US-only validation: 1–3 hours.

When to choose which

Choose Experian if:

• You validate addresses outside the US (250+ countries — RevAddress can’t do this).
• You need a full data-quality suite — match/merge, dedupe, enrichment, governance.
• You need enterprise procurement posture — signed SLAs, dedicated onboarding, and a contract your legal team can paper.

Choose RevAddress if:

• Your address volume is US-centric.
• You want flat, published pricing with no sales quote and no annual commitment.
• You need USPS DPV codes, batch with fault isolation, or address extraction.
• You want validation plus the full USPS shipping stack under one key.
• You want to ship today instead of after a procurement cycle.

The bottom line

Experian Address Validation is an excellent enterprise data-quality platform. If you’re global, or you’re standardizing all of your customer data and not just addresses, get a quote — it’s the right tool. But for US-focused teams, its quote-only, suite-oriented, annual-commitment model means you pay for scope and scale you can predict and coverage you don’t use. RevAddress gives you USPS-native validation at a flat monthly rate you can read off a page today — and you can have a working API call before Experian’s sales team returns your email.
