Solution

Postal code validation is part of address verification and supports accurate tax calculations. It checks that the postal code matches the country-specific format (character length, etc.) at the customer billing level; it does not verify that the postal code actually exists. Chargebee does not allow this validation to be disabled because of its role in tax compliance.

Steps to Set It Up

1. Review tax integration settings
   Go to Settings > Configure Chargebee > Taxes. Under EU Region configuration, check Enable location validation and ensure settings match your postal code requirements. Consult a tax advisor for local compliance.

2. Understand address verification
   Postal code validation is part of the broader address verification used to calculate tax by customer location.

3. Use alternatives where possible
   You cannot disable postal code validation when adding or updating a customer address. You can change other address fields: Customer > select a customer > Update Billing Info.

Important Notes

• Postal code validation is required for tax compliance and cannot be bypassed.
• Chargebee does not publish a per-country list of postal code validation rules.
• Keep tax settings up to date to avoid compliance issues.
• For more customization options, contact Chargebee Support or your tax advisor.
