Clearer.io Address Validator

Address Validator has worked well for us. When I had an issue they responded immediately, which is unusual given our timezone and uploaded the applicable code I needed. I felt their customer support was excellent! We have just activated the warnings for "no street number" and "address to long". Hopefully, this will reduce how many times we have to manually intervene when the order fails to flows through to our CRM because of bad data entered by the customer.
