Automatically flag potential incorrect address on orders - Automatically put order on hold until staff member checks address manaully

At least once a week we get the customer that fails to put the first line of their address on the order.

The most common is putting the house number, followed by the county or city, they forget to put a road name leading to a failed delivery.

I understand that it will not catch everything, sometimes customers put the whole address on one line, sometimes they put the house number on line 1 and the road on line 2 etc, but it might catch some dodgy addresses? particularly the customers that do not put the road name on the address.

My suggestion would be to flag the order if both line one and line two of an address are less than 5 characters each, flag it as a potential incorrect address, put it on hold and alert via email or a popup etc to check the order address.

We would click into the order, check the address and take it off hold if the address looks ok, otherwise we can contact our customer for the right address and dispatch at a later date.

Saves wasted time serving customers who cannot even give their address correctly.

Thanks
