# Can I use another address validation service instead of the AvaTax address validation?

Yes. AvaTax [Sales Tax](https://developer.avalara.com/certification/avatax/sales-tax-badge/) certification requires that you use an address validation service. You aren’t required to use the AvaTax address validation service. If you do use ours, then follow the requirements described in this guide.
