👋 Hi there! Let me take a look

reef shell Apr 22, 2026, 12:38 PM

#

Thank you Arran

#

I can see the registration_number: 000000000, but I'm not seeing a request where it was updated

reef shell Apr 22, 2026, 12:43 PM

#

WE updated the registration number from the dashboard interface

#

from here

#

the new value should be 000000042

ashen canyon Apr 22, 2026, 12:50 PM

#

Thanks. I can see where it was updated via the Dashboard now. This is your tax settings, which is separate from the business registration number

reef shell Apr 22, 2026, 12:51 PM

#

Can we update the registration number from the interface then ?

#

Or is the update only available from the API ?

#

For french companies the Tax SIREN number and the registration number are basically the same hence the confusion

ashen canyon Apr 22, 2026, 12:56 PM

#

Ah, ok. You can update it from the API via company[registration_number]: https://docs.stripe.com/api/accounts/update#update_account-company-registration_number

#

I'm checking where this would be on the Dashboard. I'm not sure I have a French account handy right now, but typically it would be under Business details: https://dashboard.stripe.com/settings/business-details

reef shell Apr 22, 2026, 12:57 PM

#

#

When I updated the SIREN number I get this pop up warning

#

do you know if someone needs to manually accept the update ?

Hello! I'm taking over for my colleague who had to step away, please give me a few minutes to catch up 🙂

#

Thank you @jovial sorrel

#

There's no manual acceptance needed, however, Stripe will try to automatically verify the new business details with the information it already has and if it can't it will prompt you for supporting documents (e.g. business regitration, government ID).

reef shell Apr 22, 2026, 1:14 PM

#

even in a sandbox ?

jovial sorrel Apr 22, 2026, 1:16 PM

#

Ah I didn't catch that you were using a sandbox! In this case, we have test data you can use for verification to simulate different success or failure cases. See https://docs.stripe.com/connect/testing?accounts-namespace=v2#identity-verification

reef shell Apr 22, 2026, 1:18 PM

#

Ho this is nice

#

Does it mean that if we go to production the registration number returned by the API will be the same as the SIREN number (french companies only) ?

#

I changed the tax number in the dashboard to 000000001 but it didn't update the company.registration_number in the api response (see request_id req_f7fbIP1ud8z4gw)

#

Sorry, do you have any update ?

jovial sorrel Apr 22, 2026, 1:35 PM

#

Sorry for the delay! I was juggling a few threads and missed your follow-up question.

#

I wouldn't expect this to behave differently in a sandbox VS production but let me do some quick research.

reef shell Apr 22, 2026, 1:40 PM

#

Thank you

jovial sorrel Apr 22, 2026, 1:50 PM

#

It looks like the SIREN is represented in the API as company.tax_id which is distinct from company.registration_number: https://docs.stripe.com/api/accounts/update#update_account-company-tax_id

reef shell Apr 22, 2026, 1:51 PM

#

Yes, nice.
I have a follow up question though:

we can update the tax_id but we cannot fetch it. So how are we supposed to do ?

#

and also what is the registration number representing then ? how can it be updated in the interface ?

jovial sorrel Apr 22, 2026, 1:56 PM

#

Our API reference states that the company.registration_number is:

The identification number given to a company when it is registered or incorporated, if distinct from the identification number used for filing taxes. (Examples are the CIN for companies and LLP IN for partnerships in India, and the Company Registration Number in Hong Kong).

And I think this can only be updated during onboarding or via the API.

#

What is your use case for fetching / updating these?

reef shell Apr 22, 2026, 1:58 PM

#

We want to check if the french company installing the app is already present in our database

#

The reliable way to match an existing company is to compare their registration number

#

In France registration_number and tax_id are the same number

jovial sorrel Apr 22, 2026, 2:25 PM

#

Thanks for sharing and sorry again for the delay, I haven't been able to find more about this but I'm still looking 🙏

jovial sorrel Apr 22, 2026, 2:44 PM

Alright, it looks like company.tax_id is considered restricted KYC (know your customer) data and there is a process to grant platforms permission to fetch this data for connected accounts. However, I cannot do that so you'll need to contact support via https://support.stripe.com/contact - this is an AI assistant that collects information about your request before connecting your to a human agent. Please explain your use case and ask to speak with an agent.
