Troubleshooting Tax ID validation

Depending on your location and jurisdiction requirements, Mailchimp will verify your Tax ID when you save your tax information and again before you complete any purchase. If you’re having trouble saving your Tax ID, there are steps you can try depending on the error.

There was an issue validating that address

Mailchimp verifies your primary contact address first, and then your Tax ID. If the “There was an issue validating that address” error appears when entering your Tax ID, it means that we can’t validate the entered address. After you enter a valid address, Mailchimp will try to verify your Tax ID.

Enter a valid TAX ID or leave blank

The “Enter a valid TAX ID or leave blank” error appears if your address is valid but the system can’t validate your Tax ID. There are 2 common issues to check with this error.

• Match your address and Tax ID
  Your Tax ID and primary contact address need to match for a successful validation. Edit your primary contact address to match the country where your Tax ID is registered. If you need to save an additional address that doesn’t match your tax registration, you can change your contact information in other places in your account.
• Check your Tax ID formatting
  Your Tax ID won’t validate if it’s entered in an incorrect format. When you enter your Tax ID, check for formatting errors. Be sure to include any spaces, numbers, letters, and special characters. Check with your local tax authority if you don’t know how your Tax ID should be formatted.
