Experian Address Validation (QAS) vs RevAddress: What Quote-Only Pricing Actually Costs You in 2026

Experian’s address product has worn several names. You may know it as QuickAddress Pro, as QAS Pro On Demand, or by its current branding, the Experian Data Quality Address Validate API. It is a mature address capture and validation platform built for large contracts, covering 245 countries and territories, sold as part of Experian’s wider Data Quality suite.

If you are standardizing address data across dozens of markets with a procurement team behind you, it is a strong choice. Most teams evaluating it are not that. They are a developer who needs one country validated to USPS standards, wants to read a price off a page, and does not want a sales call to get a POST endpoint working.

That gap is what this post is about. It does not contain an invented Experian price, because Experian does not publish one and a made-up per-lookup rate is worse than no rate at all. What it contains instead is what Experian does publish, what a quote has to pin down before you can compare it to anything, and what published flat pricing looks like on the other side. RevAddress, which publishes this site, is that flat-rate comparison.

What Experian actually publishes about price

Two things, and they are more useful than they look.

The dollar figure is quote-only. Experian’s developer documentation is explicit: “Please contact us for details on our costs of submitting a request to the API.” Capterra, G2 and GetApp all carry it as pricing-not-provided; one lists a starting price around $1,000 without stating the unit or the term. That is standard for enterprise data-quality software and not a criticism. It does mean any per-lookup number you see quoted for this product online is somebody’s negotiated contract, not a rate card, and you cannot budget against it.

The metering rule is published, and it is a good one.

You pay for successful lookups only. A timeout, a malformed request, a rejected key or a no-match costs nothing. That is better than several vendors in this category and it belongs in the comparison. It is also the kind of term that lives in documentation rather than in a contract, so confirm it survives into yours.

What a quote has to pin down

Because the rate is negotiated, the useful work is knowing what to negotiate. Six questions decide whether an Experian quote is comparable to a published price:

1. The per-credit rate, and the volume band it applies to. Ask for the ladder, not the entry number.
2. The annual minimum. This is the one that moves the effective per-lookup cost most. A commitment sized above your real volume raises your true rate for every lookup you do make, and enterprise quotes are usually annual.
3. Whether the no-charge-on-failure rule is contractual. It is in the docs. Get it in the agreement.
4. What enrichment costs. Experian’s costs page carries separate sections for address requests and for enrichment. Geocodes, demographics, property and utilities data are their own line, and a checkout that appends a geocode is making a different request than one that only validates.
5. Overage treatment. Hard stop, soft overage at the contract rate, or soft overage at a penalty rate. The third is common and expensive.
6. Term, renewal and price-lock. Multi-year commitments usually buy a lock. Auto-renewal usually carries an opt-out window measured in months.

Every one of those is knowable before you sign, and none is knowable from a website. Budget the procurement time, not just the money.

The number to compare a quote against

Flat monthly pricing gives you the other half of that comparison. These are published, they are the same figures the API meters against, and they do not move with your usage inside the plan’s request cap:

RevAddress pricing, which renders from the catalog the API bills against.

One caveat before you use that table. What those prices buy depends on whose USPS license the postal data runs on, and the next section is that answer. Reading the table without it would make it look like something it is not.

Which license the USPS data runs on

Experian holds its own postal data agreements. You pay Experian, and you never see one.

RevAddress is built the other way round. Two routes:

Census-based standardization, at no cost. Standardization, geocoding and address extract run against the US Census Bureau’s public address inventory. 1,000 requests a month on the free key, no USPS license, no per-lookup fee. It puts an address into correct postal form and returns street-level coordinates. It does not return DPV, ZIP+4 or a USPS deliverability flag, and the response says so in classification and userMessage rather than leaving you to infer it. RevAddress is not a CASS-certified vendor and does not perform NCOA processing.

The full USPS suite on your own license. You sign the USPS Addresses API agreement, you pay the USPS fee curve directly, and you point RevAddress at your credentials. The whole postal stack then runs on your license and on this infrastructure: DPV verification with ZIP+4, CMRA, vacant and business flags, plus rates, service standards and tracking, with label creation and voids at the Pro tier. RevAddress manages the OAuth lifecycle, the rate-limit budget, the caching policy and the retries; the Postal Service relationship and its reporting stay in your name, which is the opposite of what a reseller contract gives you. USPS bills monthly consumption at a single tier and rounds partial thousands up, which at 25,000 lookups a month is $106.25 on top of the plan fee and at 100,000 is $400.

So a like-for-like total against an Experian quote at 25,000 US lookups a month is $79 plus $106.25, or $185.25. At 100,000 it is $599. Those are the numbers to hold a quote against, and unlike a per-lookup rate they do not need renegotiating when your volume moves inside the tier. The USPS pricing breakdown walks the whole fee curve and the license process.

For US addresses specifically

The DPV distinction is the one worth understanding rather than skimming. With a USPS license connected, a validation response carries the Postal Service’s own Delivery Point Validation indicator: Y for a confirmed delivery point, N for not confirmed, D for confirmed but missing a secondary unit, S for a secondary that does not exist. That is a diagnosis, not a verdict. D on a customer record means ask for the apartment number. N means stop shipping there. Experian returns its own confidence and match codes, which are perfectly usable and one abstraction removed from the postal signal underneath.

The API surface, side by side

Experian takes a full address to POST /address/validate/v1 with the key in an Auth-Token header, and returns a verified match with a confidence value.

RevAddress takes a flat payload to POST /api/address/validate with the key in X-API-Key. GET with query parameters works too.

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"
}'

With a USPS license connected, the response carries the standardized address, ZIP+4 and the DPV code:

{
"address": {
  "streetAddress": "1600 PENNSYLVANIA AVE NW",
  "city": "WASHINGTON",
  "state": "DC",
  "ZIPCode": "20500",
  "ZIPPlus4": "0003"
},
"additionalInfo": { "DPVConfirmation": "Y", "business": "Y", "vacant": "N" },
"resolution": {
  "classification": "deliverable_exact",
  "nextAction": "done",
  "userMessage": "USPS confirmed this address."
}
}

On the free key the shape is the same and the honesty is in the fields. There is no ZIP+4, no additionalInfo, and the classification says what happened:

{
"address": {
  "streetAddress": "1600 PENNSYLVANIA AVE NW",
  "city": "WASHINGTON",
  "state": "DC",
  "ZIPCode": "20500",
  "ZIPPlus4": null
},
"additionalInfo": null,
"verificationSource": "census_geocoder",
"coordinates": { "lat": 38.8977, "lng": -77.0365 },
"resolution": {
  "classification": "standardized_unverified",
  "nextAction": "upgrade_for_dpv",
  "userMessage": "Standardized against the U.S. Census Bureau master address file. USPS delivery-point (DPV) confirmation is not included on the free standardization tier."
}
}

A validator that returns the same shape whether or not it verified anything is the failure mode this design exists to avoid. Read classification, not a boolean.

Migrating US validation off Experian

You do not have to move everything. Keeping Experian for international markets and the wider suite while routing US volume elsewhere is the common shape.

1. Get a free key at revaddress.com/signup. 1,000 requests a month, no card, no call.
2. Swap the endpoint. POST /address/validate/v1 becomes POST /api/address/validate. The Auth-Token header becomes X-API-Key.
3. Flatten the payload. Top-level streetAddress, city, state, ZIPCode. Aliases resolve, so street_address, address1, line1, zip and zip_code will not return a 400.
4. Map the result. Experian’s confidence and match values become resolution.classification plus, on a connected USPS license, additionalInfo.DPVConfirmation.
5. Move bulk jobs to POST /api/batch/validate, 50 per call, each settled independently so one malformed record returns its own error rather than failing the batch.
6. Run both in parallel on real traffic before the renewal date, not after. A free key makes that cost nothing.

Typical time for a single US validate call: a few hours.

Which one to pick

Experian, if you validate outside the US, need match and merge, profiling, enrichment or governance alongside addresses, or need the procurement posture that comes with an enterprise contract: signed SLAs, dedicated onboarding, and paper your legal team recognizes.

A published flat price, if your volume is US-centric, you want a number you can read today and forecast next quarter, you want the raw USPS DPV code on your own license rather than a layer above it, or you want to ship before a procurement cycle finishes. If a full list cleanse is the whole job and an API is not, List Clean takes a CSV from $19 with no contract and no per-record metering.
