tax_id_invalid is the Stripe error for a customer tax ID whose value doesn’t match the format of its type, for example missing digits. Stripe checks the format when the ID is added, before any government database check.
**Short answer**
Check the type first: each country and ID has its own enum, such as eu_vat, gb_vat or us_ein. Then match the example in Stripe’s table, including any country prefix. Show the error next to the field so the customer can fix it, and retry.
Rather not fix it yourself? [**Stripe Billing Fix and Setup**](https://app369.com/fixed-price/stripe-billing-setup/) handles it at a fixed price, agreed before work starts.
## **Why Stripe rejects the tax ID, and the fix**
1. 01 ### **The value is missing digits or has extra characters**
> “The tax ID number provided is invalid (for example, missing digits).” [**Stripe, Error codes (tax_id_invalid)**](https://docs.stripe.com/error-codes) A short number, a pasted space or a missing country prefix fails the format check. Compare the value with the example for its type.```
await stripe.customers.createTaxId('cus_123', {
type: 'eu_vat',
value: 'DE123456789',
});
```
2. 02 ### **The type doesn’t match the number**
> “Check that the value matches the format for the selected country and tax ID type.” [**Stripe, Error codes (tax_id_invalid)**](https://docs.stripe.com/error-codes) A Great Britain VAT number (GB prefix) sent as eu_vat, or a German tax number sent as eu_vat instead of de_stn, fails. Northern Ireland numbers (XI prefix) do use eu_vat. Let the customer choose the country and ID type, and map that to the right enum.
3. 03 ### **The form sends every ID as one type** A single VAT field hard-coded to one type breaks for customers in other countries. Checkout can collect tax IDs for you with tax_id_collection; on your own forms, keep a type list per country.
4. 04 ### **A valid format is taken as a verified ID**
> “For all other tax ID types, Stripe only checks the format.” [**Stripe, Customer tax IDs (Validation)**](https://docs.stripe.com/billing/customer/tax-ids) Also check: passing the format check doesn’t mean the ID exists. Stripe checks EU VAT, GB VAT and Australian ABN numbers against government databases afterwards; for other types it checks the format only.

Questions
## **More on this error**
**Does an invoice show an unverified tax ID? **+
Yes. Stripe says the invoice includes the customer tax ID whether or not it is valid, so checking the ID is your responsibility.
**How do I test verification in a sandbox? **+
For EU VAT, GB VAT and ABN types, use 000000000 for a successful verification and 111111111 for an unsuccessful one.
**Can you fix it for me? **+
If one bug is the whole problem, the App Fix Ticket covers it: a written diagnosis first, then the fix. If the app has more going on, the Launch Check is a written check of the whole app. Each issue found is rated critical, high, medium or low, with where it is and how it was confirmed. No issues worth fixing, no charge. If the Launch Check finds nothing rated medium or higher, Simon refunds the full $450. You keep the report either way. This applies to the first 10 Launch Checks bought after October 30, 2026.
