Anthropic, PBC doesn't publish a VAT number. Here are the IDs that actually exist.
If you searched for "anthropic pbc vat number", you are trying to fill a supplier field on an invoice, an expense claim, or a reverse-charge entry. The short answer is that the US parent entity does not hold a single VAT number anywhere. The long answer is a small set of real registration IDs (EU Transparency Register, UK Companies House, Uzbekistan VAT, Florida Sunbiz) plus the non-resident digital services regime that Stripe handles on Anthropic's behalf. Every identifier below is sourced and citable.
“Anthropic, PBC is a Delaware Public Benefit Corporation. It does not publish an EU or UK VAT number because the US parent isn't VAT-registered there. It collects VAT under non-resident digital services schemes, which Stripe handles on the invoice.”

Jurisdictions where Anthropic collects VAT on Claude
Why people search for this, and why the answer feels wrong
Someone on the accounts payable side opens an Anthropic invoice for Claude Pro, Claude Team, or API usage. The invoice lists Anthropic, PBC as the seller, an address in San Francisco, and a VAT line in their local currency. Their accounting software has a required field called "supplier VAT number" or "seller tax ID". They search for it. They find nothing. The search continues.
The reason the search fails is that the US parent, Anthropic, PBC, is not a VAT-registered taxable person in the EU or UK. Anthropic collects VAT the way most US-based SaaS companies do, through a non-resident digital services registration scheme, and the invoice VAT line is issued by that scheme rather than by a single local tax ID. Stripe, which processes Claude billing, handles the remittance.
What the top search results for this keyword all miss is the positive list: the real, citable identifier numbers that do exist for the Anthropic group. Those are below.
How an Anthropic Claude invoice is actually identified
The seller on the invoice is always Anthropic, PBC. The VAT number field on the seller side is blank not because of a mistake, but because the remittance path does not require a locally-issued seller VAT ID. The buyer VAT ID, if you have one, is the field that changes the outcome.
The actual Anthropic identifier numbers (sourced)
Every number here is from a public register. If your accounting or legal team needs an identifier for the Anthropic group, one of these is almost certainly what you want, even though none of them is a VAT number in the EU sense.

What you were looking for vs what exists
This is the gap that makes the search unsatisfying. The right-hand column is what your invoicing system probably really needs.
| Feature | What Anthropic actually publishes | What searchers expect |
|---|---|---|
| A single EU VAT number for the seller | None. Uses non-resident digital services scheme. | Would like: e.g., EU372000123 |
| A UK VAT number on the invoice | Not published. Anthropic Limited is UK Companies House 14604577. | Would like: GB-prefixed 9-digit |
| A US Federal Tax ID (EIN) on EU invoices | Not on the invoice. US EINs are not used for EU VAT. | Would like: XX-XXXXXXX |
| A buyer-side mechanism to zero out VAT | Yes. Enter your own VAT ID in Claude billing settings. | Some way to reverse-charge |
| Legal entity identifier for compliance forms | EU Transparency Register 511227350325-42 works for lobbying and compliance contexts. | Any official-looking number |
| Proof Anthropic exists in the UK | UK Companies House filing 14604577, address 9th Floor 107 Cheapside, London EC2V 6DN. | A letter, an address |
The number that actually changes your invoice: yours
If you are hunting for an Anthropic VAT number because you want to reverse-charge your own invoice to 0 percent, the number you need is the one you already have. Adding your own business VAT ID in Claude billing settings does the thing.
Same invoice, same seller, zero extra information about Anthropic. The difference is one line of input on your side.
What to do when your accounting tool demands a supplier VAT number
Four steps, in the order most EU and UK accounts payable teams settle on. Confirm the final choice with a local tax advisor, because the correct treatment depends on your jurisdiction.
Enter your own VAT ID in Claude billing
In claude.ai or console.anthropic.com, billing section, Stripe portal, update the tax ID field with your valid business VAT number. This is the single action that matters most for future invoices.
Record the supplier as a non-EU taxable person
In your accounting tool, set up Anthropic, PBC as a vendor with a tax type of 'non-EU digital services' or 'OSS non-resident' rather than leaving the VAT number field empty in a generic EU supplier.
Attach the invoice and flag reverse-charge
Most EU accounting systems accept a reverse-charge flag on a purchase invoice. Turn it on, attach the PDF Anthropic emailed you, and let the system compute the reciprocal VAT entry for your return.
Store the identifiers you do have
In the vendor record, store EU Transparency Register 511227350325-42, UK Companies House 14604577 (for Anthropic Limited), Florida Sunbiz F240000015680, and the San Francisco HQ address. These cover most compliance field prompts that an auditor will ever ask about.
Where to find each number, in under a minute
Every identifier below comes from a page you can open right now. No login required except for your own Claude billing.
Where Fazm fits: pulling this data without screenshots
The reason most AP workflows stall on vendors like Anthropic is that the data you need lives in four different portals (console.anthropic.com, claude.ai, a Stripe-hosted invoice page, your own accounting tool). Screenshot-based automation struggles because half of those pages lazy-render tables inside dashboards, and OCR on a table of tax codes is fragile.
Fazm is a consumer Mac app that reads the real macOS accessibility tree through AXUIElement, not pixels. That means it can walk your Claude billing pages, your Stripe invoice pages, and your accounting software as structured data (buttons, rows, input fields, values) and move numbers between them. It works with any native Mac app, not just the browser, and it is a finished consumer product, not a developer framework you have to wire up.
Let a Mac agent pull your Anthropic invoice data for you
Fazm uses real accessibility APIs, not screenshots, to drive Claude billing, Stripe invoice portals, and your accounting software together.

What is Anthropic, PBC's VAT number?
Anthropic, PBC (the US parent, domiciled at 548 Market St, PMB 90375, San Francisco, CA 94104) does not have a single EU or UK VAT number. It is a Delaware Public Benefit Corporation, not a European taxable person. Anthropic charges VAT on Claude Pro, Team, and API billing to customers in VAT-collecting jurisdictions under the non-EU digital service provider rules, which means it uses Stripe's tax engine and its One-Stop-Shop style registrations rather than a single visible VAT ID on the invoice footer.
What registration number does Anthropic, PBC actually have in the EU?
Anthropic, PBC appears in the EU Transparency Register with ID 511227350325-42, first registered on 31 May 2023. That number is a lobbying disclosure identifier, not a VAT number. You can use it to confirm the legal identity of Anthropic, PBC for EU regulatory purposes, but it will not satisfy a VAT validation check on your own invoice.
Does Anthropic have a UK company registration?
Yes. Anthropic Limited is registered with UK Companies House under company number 14604577, incorporated on 19 January 2023, with a registered office at 9th Floor 107 Cheapside, London EC2V 6DN. That is a distinct UK subsidiary, not the same legal entity as Anthropic, PBC. It may or may not hold a UK VAT number at the time you read this; Companies House itself does not publish VAT numbers.
Where is Anthropic actually registered as a VAT payer?
Anthropic was added to Uzbekistan's virtual VAT office as a value-added tax payer on 2 February 2026, per the Interregional Tax Inspectorate for Large Taxpayers. Anthropic also collects VAT on Claude subscriptions and API usage across the EU-27, UK, Australia, and other jurisdictions, and in most of those it operates under a non-resident digital services registration scheme rather than a locally published VAT ID.
Why is the 'Anthropic VAT number' field empty on my Stripe invoice?
Because Stripe is collecting VAT from you on Anthropic's behalf under a non-resident scheme. The seller identity on the invoice is Anthropic, PBC, but the VAT line is computed and remitted using Anthropic's One-Stop-Shop or equivalent registration, and the invoice typically shows only the tax amount and your jurisdiction, not a seller VAT ID. If you have a valid business VAT ID of your own, enter it in your Claude billing settings and the next invoice will reverse-charge to 0 percent.
What do I put in my accounting system for 'supplier VAT number' when the vendor is Anthropic?
If your local rules require a supplier VAT number field to be populated, most accounts payable teams use one of three options: (1) enter your country's non-resident digital services scheme code (for example, the EU OSS identifier Anthropic uses for your member state), (2) record the supplier as a non-EU taxable person and flag the invoice as reverse-charged under the OSS regime, or (3) attach a copy of Anthropic's invoice and note in the memo field that no supplier VAT ID is issued. Confirm the right choice with your own tax advisor, since the correct treatment depends on your country.
Can I use Fazm to pull Anthropic invoice VAT data out of my accounts automatically?
Yes. Fazm is a consumer Mac app that reads the macOS accessibility tree directly (AXUIElement) instead of taking screenshots, so it can navigate console.anthropic.com, claude.ai billing, and Stripe portals as structured data. You can write a plain-English instruction like 'open Claude billing, download the last three invoices to my Desktop, and extract the VAT amount and jurisdiction from each', and Fazm will drive the browser, the terminal, and Finder together through real accessibility APIs. It works with any Mac app, not just the browser, and it is a finished consumer app, not a developer framework.
Is the Florida corporate filing for 'Anthropic, PBC, Inc.' a tax number?
No. Florida Sunbiz record F240000015680 is a foreign profit corporation filing for Anthropic, PBC in Florida. It indicates the company is registered to do business in that US state, not that it holds a VAT or sales tax number. US sales tax is handled per state and does not use the VAT mechanism that Anthropic uses in the EU, UK, Australia, or Uzbekistan.
The answer is the set of numbers that do exist, not the one that doesn't.
Anthropic, PBC is a Delaware PBC with a lobbying identifier, a UK subsidiary, a Florida foreign corp filing, and a growing list of non-resident VAT registrations. That is the real map. Your own VAT ID is still the only one that changes the invoice total.
