# My US tax ID number (TIN) isn't verifying

If your TIN isn't verifying, it's likely because the IRS hasn't updated their database yet. This is common if your US business name was updated with the IRS within the last 3 months, or if you're registering a new business for the first time. The IRS typically takes **3–4 weeks** to process updates.
If Stripe is unable to verify your TIN with IRS records, you'll see a banner in the [Dashboard](https://connect.stripe.com/express_login) asking you to **Update your business information**.
## TIN issued within the last 3 months
If your legal name and tax ID match the details on your SS-4 confirmation letter, you can upload a copy to get verified. Stripe can only verify TINs against IRS records.
