Physical Identity Verification
CAPTCHAs, document scans, biometrics, device fingerprints — AI agents pass them all. Analog Auth verifies the one thing they can't fake: a real human at a real address, opening a real letter.
In 2026, autonomous AI agents can complete any digital verification flow — from account creation to ID upload to biometric liveness. Your entire fraud stack operates in a domain where AI is native.
AI solves every CAPTCHA variant faster and more accurately than humans. You're adding friction for real users while bots walk through.
AI generates convincing synthetic IDs. Stolen documents are available at scale. A photo of a card proves nothing about who's holding it.
Real-time face generation defeats liveness checks. The person on camera doesn't need to be real. The camera doesn't need to be real.
Antidetect browsers generate unique fingerprints on demand. One operator, a thousand "unique" devices. Behavioral analysis can't keep up.
Disposable emails cost nothing. Virtual phone numbers are a few cents. One person can have thousands of "verified" accounts in minutes.
AI agents replicate human browsing patterns, typing cadence, and mouse movements. The behavioral signals you trust are the easiest to fake.
Your platform redirects users to our verification page. They enter their name, email, and address. We run a risk pipeline, mail a letter via USPS, and they confirm with their email and code. You get a webhook. No AI agent can open a mailbox.
Your platform redirects the user to our verification page with a webhook URL. They enter their name, email, and U.S. address. We run input validation, velocity checks, USPS verification, and GeoIP screening to ensure every verification is legitimate.
A branded verification letter ships via USPS First-Class to the verified residential address. It contains a unique, time-limited code and a link to our confirmation page. Only someone physically present at that address can receive it.
They visit analogauth.com/confirm, enter their email and code. We match, compute a confidence score from IP proximity, device fingerprint, and timing signals, and fire a webhook to your platform. Done.
Redirect your user to our verification page with your platform key and a webhook URL. We handle everything — the form, the risk pipeline, USPS fulfillment, the confirmation page. When the user verifies, we POST the result to your webhook.
# 1. Redirect user to Analog Auth redirect_url = "https://analogauth.com/verify?" + urlencode({ "platform": "your_api_key", "ref": "user_12345", "webhook": "https://yourapp.com/hooks/verify", }) # 2. We handle everything. When verified, # your webhook receives: { "request_id": "vr_8x2kQ7m...", "status": "verified", "platform_ref": "user_12345", "verified": true, "confidence_score": 0.92, "address_verified": true }
You pay for results, not infrastructure. Pipeline processing, address validation, letter delivery — that's on us. You get a verified human with a confidence score, or you pay nothing.

We complement Persona, Sumsub, GeoComply, LexisNexis, and every other identity tool in your stack. They verify digital signals. We verify the physical world. Add us as a step-up tier for high-risk users, or a mandatory gate for high-value actions.
Analog Auth isn't for login flows — it's for moments where you need certainty that a real human is on the other end. Seller approval. Payout gating. Elevated privileges. The 3–5 day delivery window is a feature: it self-selects for actions worth protecting.
Require address verification before a seller can list, accept payments, or access promotional tools. One verified address per seller account. Fraud rings can't scale against physical mail.
Gate payouts behind address verification. Sellers earn normally, but funds only release after they've confirmed a real address. Catches fraud before money leaves your platform.
Stop multi-accounting before it starts. One address, one player account. Replaces spoofable utility bill uploads with deterministic proof of address — exceeding state gaming commission requirements.
Also applicable to fintech KYC, gig platform onboarding, community governance, and any high-trust action requiring proof of unique physical identity. The INFORM Consumers Act requires seller address verification on major US marketplaces. State gaming commissions require proof of address for player KYC. Analog Auth helps you comply.
Every digital verification method is being defeated by AI agents that operate natively in the digital domain. Physical mail requires a real human body at a real address. That's a constraint no software can overcome — not today, not ever.
Verification codes are cryptographically hashed at generation. We never store plaintext codes. Even a full database breach reveals nothing usable.
Every request passes through sequential fraud checks — input validation, address verification, device reputation, and more — so the verified result you receive is one you can trust.
One flat price per verified human. Pipeline processing, address validation, letter delivery — we absorb the cost. You only pay when a real person confirms they're at a real address.
Verifying your home address? You should be near your home. We treat datacenter IPs, VPNs, and Tor exit nodes as hard risk signals by design.
Verification isn't binary. We return a 0–1 confidence score combining pre-send risk assessment with post-verification signals: IP proximity, device match, and timing.
API-key authenticated. Structured logging on every request. Deterministic pipeline with clear audit trails. Designed for SOC 2 readiness from day one.
We're working with a small group of design partners to validate physical identity verification. If your platform has a fake account problem, we want to talk.
