AddressZen sits in the middle of a Zap rather than at either end, checking and correcting a US shipping address before anything else happens with it. On its own it does not send anything to a customer, but paired with Mobile Message it makes sure the text that follows lands against an address that has actually been verified, rather than whatever a customer happened to type into a form.

A Shopify order, an Eventbrite registration or a form response often carries a shipping address typed in a hurry, and a single missing unit number or misspelled street can send a delivery to the wrong door entirely. Running that address through AddressZen first, using just a street address and zip code, a street address with city and state, or a full freeform line, corrects the details before Mobile Message sends the customer a text confirming where their order or ticket is headed. The address gets checked once, automatically, before the confirmation goes out rather than after a parcel has already gone missing.
