How does Claude age verification work, and how do you get unblocked?

Published 2026-09-12 · Researched and price-checked on official sources

Claude age verification runs through Yoti rather than Anthropic: when safety systems flag an account as possibly under 18, Anthropic disables it and emails a Yoti link, reinstating the account only after the check passes. Yoti accepts a selfie, a government photo ID, or a shared Digital ID attribute.

Key facts

What matters

Anthropic requires every Claude user to be at least 18, and accounts showing indicators of minor activity stay disabled until age assurance through Yoti passes.
Yoti gives three routes: facial age estimation from a selfie with no ID document, a photo upload of a passport, driving licence or national ID, or an over-18 attribute shared from the Yoti Digital ID app.
Anthropic never sees the selfie or ID: per its help center, Yoti deletes the images once the age is checked and returns a pass or fail result.
A second, separate system run by Persona Identities handles identity and business verification, and it demands a physical government photo ID plus a phone camera for a possible live selfie.
Claude plans are Free, Pro at $20/month or $200/year, Max 5x at $100/month and Max 20x at $200/month, and Anthropic's refund page makes payments non-refundable except where the Consumer Terms of Service or local law allows.

What is Claude age verification?

Claude age assurance is Anthropic's age gate on the consumer Claude product: an account is only available to people over 18, and anyone whose account trips Anthropic's minor-activity signals must confirm their age before using Claude again. Anthropic runs that confirmation through Yoti, an outside age verification platform, rather than in house.

The sequence matters if you are locked out. Anthropic says its safety systems look for indicators of under-18 use, and that it disables accounts based on them. A notification email then carries a Yoti verification link. Pass the Yoti check and the account is reinstated. The published flow has no separate form to submit first and no described human review step.

Anthropic published the age assurance article on May 18, 2026. It surfaced as a front-page Hacker News story on September 12, 2026, where the thread carried 563 points and several hundred comments, most of them about privacy rather than about how the check actually works. What that discussion largely missed is that Anthropic now runs two separate verification systems, and only one of them is about age.

The three ways to verify your age with Yoti

Yoti offers a choice of three methods, and the one most people overlook is the route that needs no documents at all.

Facial age estimation: take a selfie and Yoti's technology estimates your age from it. No ID document is needed.
ID verification: photograph your ID, such as a passport, driving licence or national card, and upload it from your device. Anthropic points readers to Yoti's own list of supported documents for country-specific options.
Yoti Digital ID app: if you already hold a verified over-18 attribute in the Yoti app, you share that attribute instead of running a fresh check.

Two gaps are worth knowing before you start. Anthropic's article states no fee for the age check, and it describes no fallback for anyone who fails all three methods. If you hold none of the accepted documents, facial age estimation is the only route that does not depend on paperwork.

What Yoti does with your selfie and ID

The data handling section of Anthropic's article is unusually specific, and it is the part to read before uploading a passport photo to any age gate.

Anthropic describes Yoti as an independently audited age verification provider for SOC2 compliance.
Your selfie, document images and any personal data are, in Anthropic's words, deleted by Yoti as soon as your age is checked.
Anthropic never sees your ID or your image. It receives a pass or fail result and says it does not process or store personal data from the verification.

What the article does not give you is a retention window beyond that immediate deletion, or an appeals route specific to the age check. If a Yoti result looks wrong to you, the documented paths sit in other Anthropic pages, and the app store signal described next covers the most common false flag.

Blocked at sign-in instead? That is the app store age signal

If no Yoti email ever arrived and you were stopped while signing in on mobile, you hit a different mechanism with a different fix.

Anthropic requires all users to be at least 18 years old to create and use a Claude account. On the mobile apps, the access message appears when the App Store or Play Store has identified you as under 18 from your store account information. Anthropic states that in certain US states, new laws require app stores to verify users' ages and share that information with app developers, and that Claude uses it to enforce the minimum age. That rollout is staged state by state.

The correction does not happen on Anthropic's side. Anthropic says it has no access to app store account information and cannot change it, so iOS users go to Apple Support and Android users to Google Play Support. Where the account belongs to a family group such as Apple Family Sharing or Google Family Link, the birth date may have been set by a parent or guardian and has to be fixed there.

Age assurance vs identity verification: two different Claude checks

Anthropic now runs two verification systems that get conflated in almost every discussion of the 18+ rule. Age assurance, handled by Yoti, answers one question: are you 18 or over? Identity and business verification, handled by Persona Identities, answers who you are, and it applies to certain capabilities, to routine platform integrity checks, and to compliance obligations.

The Persona side is the stricter one. Anthropic lists the requirements as a valid government-issued photo ID held physically in hand, a phone with a camera, and the possibility of a live selfie. Verifying for an organisation adds legal name, address and business registration number. Accepted documents are passports, driving licences, state or provincial ID cards and national identity cards. Rejected outright: photocopies, screenshots, scans, photos of a photo, digital or mobile IDs, student IDs, employee badges, library and bank cards, and temporary paper IDs.

The privacy split is the practical difference. Anthropic is the data controller for verification data and says its fraud prevention partners are contractually limited to providing verification and fraud prevention. ID and selfie images are held by Persona rather than on Anthropic's systems, though Anthropic can reach verification records through Persona's platform when it needs them, for example to review an appeal.

What a disabled account means for a paid Claude plan

A locked account is a billing question as much as a support question, and Anthropic's own pages answer most of it. Plan prices, checked on September 12, 2026, run Free at $0, Pro at $20/month or $200/year, Max 5x at $100/month and Max 20x at $200/month.

On refunds, Anthropic's refund article is blunt: except as expressly provided in the Consumer Terms of Service or where required by law, all payments are non-refundable. It does describe a refund request flow inside the account's help messenger for payments the terms define as refundable. Customers in the European Economic Area and the United Kingdom get a 14-day window from purchase, prorated according to use. If you paid on iOS, Apple processed the payment, so only Apple can review or issue that refund, through reportaproblem.apple.com.

Anthropic's safeguards article covers what still works after a suspension, and it is more generous than people expect. A banned Free, Pro or Max account can still log in at claude.ai to export its data or delete itself without contacting Anthropic, and self-serve exports are open to all banned users, though what you can pull may be limited by the violation behind the ban. The appeal form sits behind that same login.

If you were flagged incorrectly, what actually works

Two things decide how quickly this resolves: which system flagged you, and whether the flag came from Anthropic or from an app store.

You got the Yoti email. Complete the check with whichever method you can satisfy. A pass reinstates the account, per Anthropic's article.
You were stopped at mobile sign-in with no Yoti email. The age came from Apple or Google, so the birth date has to be corrected on the store account, not with Anthropic.
You were asked for identity documents rather than age. Work through the Persona flow; Anthropic says it can review those records when an appeal is filed.

Set expectations on timing. Anthropic's appeals page carries a standing notice that response times are longer than normal because of a recent launch and higher email volume, and the appeal form requires logging in with the affected account. Read the Hacker News thread and you find the same wall: hundreds of comments about privacy and about cancelling plans, and no documented exemption for paying customers in either the thread or Anthropic's documentation.

FAQ

What is the minimum age for Claude?

Anthropic requires users to be at least 18 years old to create and use a Claude account, and describes the consumer product as available only to people over 18. Accounts showing indicators of minor activity are disabled until a Yoti age check passes.

Does Claude age verification need a passport?

No. Facial age estimation from a selfie needs no ID document. A passport, driving licence or national ID photo is one of three options rather than a requirement, and the Yoti Digital ID app can share an existing over-18 attribute instead.

Is Yoti safe to use for Claude age verification?

Anthropic describes Yoti as an independently audited age verification provider for SOC2 compliance and says your selfie, document images and personal data are deleted by Yoti once your age is checked. Anthropic says it receives only a pass or fail result and never sees the ID or selfie.
