Stop bad data
before it becomes trusted data

Real-time verification, fraud and suitability signals. One API.
Verify the data, corroborate identity details and expose risk before records reach the systems that depend on them.

Free check, no sign-up needed. Or create an account for £5 free credit with a business email.

Stop wasted records

Catch invalid and unreachable records before they hit your CRM, dialler or campaign.

Corroborate identity

Check supplied name, address and date of birth against UK identity records and mobile-network data.

Expose risk

Fraud, breach exposure and recent SIM changes, in real time.

Know before you trust

Decide what happens to the record before anything downstream relies on it.

One request. The signals you choose.

Most validation tools answer one narrow question about one field. A single Multi-validation request can combine supported Provero checks, so you can read whether the data works, whether the identity details match, what risk is attached and the number's TPS status side by side.

Sent from form submissions, batch jobs, system integrations or KYC workflows.

Customer feedback

What teams using Provero say

"We tested Provero as an additional layer for our KYC data provenance due diligence and the outcome reports were very insightful. We could identify data that was part of a legacy breach, data that existed on national suppression files along with detailed phone and email validation flags. Really impressive solution and would recommend to anyone onboarding new data or to check existing datasets. It enabled us at Dataxcel to make informed decisions especially around compliance."
Lorcan Lynch, Dataxcel

No plans. No commitment. Top up and pay per check.

Frequently Asked Questions

What Provero checks, how fast it runs and what it costs.

Does Provero do more than just email and phone validation?

Yes. Provero checks five areas of the same record, contact data, address services, identity and age, fraud and risk, and compliance. Phone, email, name, UK and international addresses, database and mobile-network KYC, age checks, SIM swap, mobile contract type and tenure, IP fraud, breach exposure and TPS screening are available through one API.

How is Provero different from a single-purpose verification API?

A point solution tells you whether one field passed one check. Provero can run that same single check, and it can also tell you whether the identity details match independent data, whether there is fraud or breach exposure attached, and whether you are allowed to make contact, in one request. You know far more about the record before you decide what happens to it.

How does Provero help decide whether a record is usable?

Different uses demand different confidence in a record. One that is good enough to send a marketing email may not be good enough to approve an identity-sensitive action or open an account. Provero tells you more about the record, whether the data works, whether the identity details match independent mobile-network data and what risk is attached, so you can set the bar your use case needs and act on it.

How does Provero fit into a KYC or IDV workflow?

Most often as the step before it. KYC checks cost pounds per record. Provero costs pennies, so running a record through verification and risk checks first means you are not paying to run identity checks on data that was never going to pass. Dead numbers, undeliverable emails and records with breach exposure get caught before they reach the expensive part of the waterfall. If you need the identity check itself, Provero offers two. KYC Checks verify supplied name, date of birth and address against UK identity records. Mobile network KYC corroborates the same details against mobile network data, and runs in the same request as everything else. Use either, or combine them in one verification workflow.

What does breach exposure tell me?

Whether an email address, phone number or IP appears in known breach data, how many separate breaches, and how old the first one is. That last figure does most of the work.

On a single record it means very little, because around half of real consumer data carries breach exposure. It works across a whole source. Clean sources run at roughly 50% exposure with a first breach three to five years old. Recycled stolen data runs at 70% to 100%, with a first breach nine to eleven years old, and the same records turning up in six or more breaches each. A supplier can lower a breach rate. Nobody can make old data young.

We call that read the Breach Age Index.

How it works and the benchmarks behind it →

Can Provero analyse bulk data?

Yes. Most checks run as a real-time API call or as a bulk upload, and the services page shows how each one can be used. A single bulk workload of 1.4 million records has been processed with two checks running against every record, 2.8 million lookups in one file. Bulk speed depends on how far the workers scale, so a 100,000-record file takes about twelve minutes on a cold run and completes in under three once autoscaled.

How fast is it?

HLR responds in approximately 467ms at the 95th percentile, measured at 50 requests per second under sustained load rather than idle, and a 100,000-record HLR bulk file completes in under three minutes once the workers have scaled to it.

Can Provero handle production volume?

Yes. 1.4 million records have been processed in a single bulk upload, with two checks running against every record, 2.8 million lookups in one file. The platform carries ongoing API traffic and bulk processing from active users every day. It is also simple enough to check a single record.

Is my data secure?

Yes. Provero is designed with enterprise-grade privacy and security at its core. Our platform is built entirely with ISO 27001 compliance standards in mind, employing end-to-end encryption (TLS in transit and AES-256 at rest), strict access controls, and fully GDPR-compliant data processing workflows.
