Prove Review
6.8/10US phone-centric identity-verification and authentication platform (Prove Identity, Inc., formerly Payfone) whose PRO Model verifies a consumer through phone possession, reputation, and ownership rather than a document first, carrying the freshest US sportsbook roster on vendor record (FanDuel 2023, BetMGM 2024, Hard Rock Bet 2025), a PA PGCB Registered gaming registration to 2028, a clean conduct record, and no public pricing.
Our read
A differentiated phone-centric method (PRO Model: possession, reputation, ownership) with Pre-Fill onboarding that auto-fills applications with bank-grade verified data after phone-possession consent, plus Unified Authentication, Identity Manager, and Auth, but document capture is secondary and the method is US-carrier-anchored (weaker for thin or new-phone-history users), narrower than the document and AML full-stack vendors.
PA PGCB Registered (Prove Identity, Inc., DBA Prove, exp 02/21/2028, the lower PA class, not Certified) with NIST 800-63A and AAL framing, no UK DIATF, and SOC 2 and ISO claimed only, with the spotless conduct record and longer-dated registration lending the marginal edge over AU10TIX's equal-class trail.
Unusually open for the tier: a public developer portal at developer.prove.com plus API Studio, documented Pre-Fill consumer and server flows, and an Alloy orchestration partnership, held back by enterprise-only sales with no published SLA.
The freshest US sportsbook roster on vendor record, FanDuel (2023-05, the first tier-1 on Pre-Fill), BetMGM (2024-04, quoted on the page today), and Hard Rock Bet (2025-09), plus a named Head of Sports Betting and iGaming publishing in gaming media, three dated tier-1 wins across three years, stronger than a logo wall.
The cleanest file in the segment alongside Socure, no breach and no FTC, FCC, or CFPB enforcement and no privacy class action found (only a TTAB trademark opposition), independent (Apax-led, MassMutual and Capital One participation) and CEO-stated profitable at the 2020 raise, with no audited figures on record.
No public pricing, enterprise sales only, firmly in the opaque camp of the transparency board.
Methodology. Our own score, a weighted average of six dimensions, tilted toward verification coverage and compliance. Weighted on the identity-verification scale, with verification coverage first at 0.22 and compliance and certifications next at 0.20, so a differentiated phone-centric method and the freshest sportsbook roster carry a solid middle score while the lower PA class and opaque commercials cap the top. Read the full methodology
- The freshest, deepest US sportsbook roster on vendor record: FanDuel (2023-05-04, the first tier-one US sportsbook on Pre-Fill, quoting SVP Product Billy Turchin), BetMGM (2024-04-09, John Snyder still quoted on the gaming page today), and Hard Rock Bet (2025-09-30, SVP Operations Danny Crook), three tier-1 operators across three years and tier-1 trade-press covered.
- A genuinely differentiated method: the phone-centric PRO Model (possession, reputation, ownership) plus Pre-Fill solves onboarding friction rather than only checking a document, with vendor-stated 79% faster onboarding, 35% less abandonment, and a 90% match rate on the gaming page (read 2026-07-12).
- A clean regulatory-conduct record: no data breach, no FTC, FCC, or CFPB enforcement, and no privacy class action found for Prove or Payfone across targeted sweeps (2026-07-11), with only a TTAB trademark opposition on record.
- A PA PGCB Registered gaming registration (Prove Identity, Inc., DBA Prove, exp 02/21/2028) that, while the lower PA class, runs a year longer than most peers' entries, the load-bearing US anchor in a category with no gambling-license registers.
- Independent with no absorbed-parent risk: not swallowed in the IDV M&A wave, Apax Digital-led with MassMutual and Capital One participation, and CEO-stated profitable at the 2020 raise, unlike the Onfido, IDVerse, and Vespia absorptions among peers.
- Carrier-data and phone-centric dependence: the method is powerful in the US but US-anchored, exposed to carrier-data availability, and weaker for consumers with thin or new phone histories, and document capture is only secondary.
- General-purpose and US-only: the core book is banking and fintech, there is no UK DIATF and no international register, and it is not a fit for EU or UK-first or document-first operators.
- Opaque pricing: no public pricing of any kind, enterprise sales only, the opposite of the segment vendors that publish a per-check rate.
- The lower PA class: Prove holds Registered, not Certified, the lower of Pennsylvania's two classes, behind Socure, Jumio, and Shufti Pro on the register-class ladder even if the expiration is longer-dated.
US-regulated sportsbooks and iGaming operators that want to cut onboarding friction and account-opening and synthetic-identity fraud through a phone-centric Pre-Fill flow, and value a register-Registered vendor with a proven tier-1 operator roster.
EU or UK-first operators, since there is no DIATF and the method is US-carrier-anchored, document-first compliance regimes, operators serving large thin-phone-history populations, and anyone who needs published pricing.
Markets & licensing
Prove's regulatory story in gaming rests on one register entry: Pennsylvania lists Prove Identity, Inc., DBA Prove as a Registered gaming service provider, expiration 02/21/2028, on its Authorized Certified and Registered list as of 3/24/2026. Registered is the lower of Pennsylvania's two classes, below Certified, which puts Prove in the same class as AU10TIX and Veriff rather than the Certified class held by Socure, Jumio, and Shufti Pro. In a category with no gambling-license registers at all, that state entry is the load-bearing US anchor, and it runs a year longer than most peers' registrations. There is no UK DIATF entry, which is expected for a US-centric platform, and the SOC 2 and ISO artifacts that a bank and fintech book implies carry no published issuer or report class, so they read as claimed only. Prove also markets its phone-possession method against NIST 800-63A identity-proofing and AAL authentication levels, but that is vendor framing rather than a certification.
The United States is the entire business, and the gaming-relevant proof is a Pennsylvania PGCB Registered registration for Prove Identity, Inc. that runs to February 2028, the longer-dated of the peer set even though it is the lower PA class. The method is built for the American consumer: phone-possession, reputation, and ownership scored off US carrier signals, which is precisely why the freshest tier-1 sportsbook roster on vendor record (FanDuel, BetMGM, Hard Rock Bet) sits on it.
There is no UK DIATF certification and no international register presence, and the carrier data that makes Prove strong is US-anchored by design. Operators with a UK or EU-first book, or those verifying large thin-phone-history populations, should look at the DIATF-certified and document-first vendors in this segment instead.

Licensing tier: One US gaming register and nothing above it: the PA PGCB Registered entry is the anchor, longer-dated than most peers but the lower of PA's two classes, against a segment where the deepest players carry DIATF certs on both sides of the Atlantic and Certified-class US entries. The SOC 2 and ISO artifacts have no issuer to check.
The register anchor is the PA Registered row. The wider footprint is a US banking and fintech book (vendor-stated 19 of the top 20 US banks) into which gaming is one vertical, all inside the United States.
No restricted-market list applies: Prove is a US-centric platform with no offshore gambling posture to restrict (2026-07-12).
Platform & capabilities
The feature set: what's built in. Capabilities light up when present. Anything not shown isn't offered or isn't disclosed.
Integrations & engineering
One contract and one API instead of a separate deal per studio, feed, or PSP. Here's what connects, how fast, and on what stack.
Everything runs off the phone signal. A REST API and API Studio expose the identity and verification flows, Pre-Fill has documented consumer and server flows on developer.prove.com, and possession is established through silent Mobile Auth, SMS OTP, or Instant Link before any attribute is released. The gaming relationships are with operators (FanDuel, BetMGM, Hard Rock Bet) rather than with the B2B platforms and PSPs in this directory, so the directory cross-edges are thin and the weight is on the named-operator evidence class, with an Alloy orchestration partnership the one platform-layer edge.
No public claim for iGaming (2026-07-12). The developer portal and API Studio let engineering read the surface immediately, but API key pairs and production access come through account setup, so the real calendar comes out of the sales and onboarding process.
Products & tools
One phone-centric identity platform: Pre-Fill auto-completes an application with bank-grade verified data after the consumer proves phone possession, Account Opening activates the account on top of it, and Unified Authentication, Identity Manager, and Auth carry the same signal into ongoing recognition and step-up checks.
Prove Pre-Fill
The product behind every named sportsbook win: once a consumer proves possession of their phone, Pre-Fill auto-completes the signup form with verified bank-grade data pulled from authoritative sources, then authenticates against account-opening and synthetic-identity fraud.
- Auto-fills the application with verified consumer data after phone-possession consent, so only the specified consumer can populate their own info
- Deployed at FanDuel (2023, the first tier-one US sportsbook on Pre-Fill), BetMGM (2024), and Hard Rock Bet (2025)
- FanDuel PR claimed account opening up to 80% faster and onboarding in as few as 3 clicks (2023-05-04)
- Gaming-page metrics: 79% faster onboarding, 35% less abandonment, 90% match rate (vendor-stated, read 2026-07-12)
- Documented consumer and server flows on the public developer portal at developer.prove.com
The PRO Model: Possession, Reputation, Ownership
Prove's differentiator is that it binds identity to the consumer's phone line rather than leading with a document, establishing possession first, scoring the number's reputation, then confirming the line is owned by the named customer.
- Possession: confirms the consumer controls the line via silent Mobile Auth, SMS OTP, or Instant Link before releasing any attribute
- Reputation: a phone-number risk score from carrier and trusted-partner signals (tenure, SIM-swap and porting risk, line type)
- Ownership: name-to-number binding against authoritative sources to prove the line belongs to the named person
- Marketed against NIST 800-63A identity-proofing and AAL authentication levels (vendor framing)
- Document capture exists but is secondary, the opposite posture from doc-first vendors
Unified Authentication & Identity Manager
The layer past onboarding: Unified Authentication runs cross-platform step-up and step-down checks, Identity Manager keeps a registry of tokenized customer identities for recognition and fraud prevention, and Prove Auth mixes passive and active authenticators by risk.
- Unified Authentication for cross-platform step-up and step-down flows
- Identity Manager: a tokenized-identity registry for fraud prevention and customer recognition, the persistent-identity graph
- Prove Auth: passive plus active authenticators tuned from low- to high-risk scenarios
- Prove Identity augments risk scoring with proprietary phone-ownership signals
- The reusable/persistent-identity story the 2026 Prove Identity Platform doubles down on
On the record
The history that matters: the milestones, the scale, the awards, and who runs it.
Prove Identity, Inc., formerly Payfone, is a New York software and data-analytics company whose distinctive method is phone-centric identity rather than document-first verification. Payfone traces to roughly 2008 to 2011 (the founding year is ambiguous across sources, with the 2020 rebrand the safe anchor) and grew into a general-purpose US identity and authentication platform whose core book is banking and fintech, vendor-stated as 19 of the top 20 US banks. It rebranded from Payfone to Prove on 2020-07-29 alongside a $100M raise led by Apax Digital and the acquisition of Early Warning Services' mobile-authentication lines, with CEO Rodger Desai telling reporters the company was already profitable at a $549M post-money valuation. A 2023 round of $40M at a ten-figure valuation added MassMutual and Capital One, and the company remains independent with no absorbed-parent risk. In April 2026 it launched the Prove Identity Platform, repositioning identity from a one-time event into a persistent trust layer spanning people, businesses, and AI agents.

The take: Socure is the direct US-lens rival, general-purpose US IDV with deeper identity data and the higher PA Certified class, where Prove counters with a differentiated phone-centric method and the freshest sportsbook roster (FanDuel, BetMGM, Hard Rock Bet). GBG matches a Certified US class and adds UK DIATF and affordability depth that Prove lacks, while AU10TIX is the equal-class peer, also PA Registered, but with a thinner gaming footprint and a heavier trust file. Pick Prove when a phone-centric Pre-Fill flow, a proven tier-1 US operator roster, and a clean conduct record outweigh the lower register class, published pricing, and international coverage.

Frequently asked
The things operators actually ask before signing.
Which sportsbooks actually use Prove, and how strong is the evidence?+
Three tier-1 US operators, each dated. FanDuel was announced on 2023-05-04 as the first tier-one online sportsbook in the United States on Prove Pre-Fill, with a quote from SVP Product Billy Turchin, covered by tier-1 iGaming trade press. BetMGM followed on 2024-04-09 for Pre-Fill onboarding plus bonus and promotion-abuse prevention across sports betting and iGaming, with Product Leader John Snyder still quoted on the gaming page as of July 2026. Hard Rock Bet is the freshest, announced 2025-09-30 for Pre-Fill plus Prove's Global Fraud Policy, quoting SVP Operations Danny Crook of Hard Rock Digital. That is the freshest US sportsbook roster on vendor record in this segment.
How does phone-centric verification actually work, and what happens for a user with a new or thin phone history?+
Prove uses its PRO Model: Possession, Reputation, Ownership. It first confirms the consumer controls the phone line through silent Mobile Auth, an SMS one-time password, or an Instant Link, releasing verified attributes only once the session has enough assurance. It then scores the number's reputation from carrier and trusted-partner signals (tenure, SIM-swap and porting risk, line type), and confirms the line is owned by the named customer through a name-to-number binding against authoritative sources. The structural limitation is exactly the thin case: a consumer with a new, ported, or non-standard line, or a thin phone history, is where the carrier-anchored method is weakest, and document capture is only a secondary fallback, so pilot those users specifically.
Is Prove a registered US gaming vendor, and at what class?+
Yes, in Pennsylvania, at the lower class. The PGCB lists Prove Identity, Inc., DBA Prove as a Registered gaming service provider with an expiration of 02/21/2028, on the Authorized Certified and Registered list as of 3/24/2026. Registered is the lower of Pennsylvania's two classes, below Certified, which places Prove alongside AU10TIX and Veriff, below the Certified class held by Socure, Jumio, and Shufti Pro. The one upside is duration: the 2028 expiration runs a year longer than most peers' entries. In a category with no gambling-license registers at all, that state entry is the load-bearing US anchor.
Any enforcement actions or privacy litigation against Prove?+
None found as of 2026-07-11. Across targeted sweeps for FTC, FCC, and CFPB enforcement and for privacy or class-action matters against Prove or its predecessor Payfone, no data breach, no enforcement action, and no privacy class action surfaced. The only adversarial matter on record is an administrative TTAB trademark opposition (Payfone Inc DBA Prove versus Proba Holding B.V.), which is a trademark dispute and not a conduct finding. That is a clean regulatory-conduct record, among the cleanest in this segment alongside Socure.
Does Prove work outside the US, and why the caution?+
It is US-anchored by design. The phone-centric method leans on US carrier and phone-line data, so its strength does not travel: there is no UK DIATF certification, no international register presence, and the reputation and ownership signals thin out abroad. Prove is also exposed to carrier-relationship and data-availability risk even inside the US. Operators with a UK or EU-first book, or those verifying large thin-phone-history populations, are a poor fit and should look at the DIATF-certified and document-first vendors in this segment instead.
