Address Verifier is built for US stores, and the US is where verification is strongest: every address checks against USPS data down to the delivery point, the exact house or unit. But your buyers aren’t all in the US, and we verify every destination they ship to. Here’s what that means country by country.
The four precision levels
Address verification isn’t binary. Depending on the country’s postal data, a check resolves to one of four levels, best to worst:
- Delivery point: the exact house, apartment, or suite is confirmed to exist.
- Premises: the building is confirmed, but not the unit inside it.
- Thoroughfare: the street is confirmed, not the number.
- Locality: only the city checks out. A weak signal on its own.
The level decides how confident we act. A delivery-point miss is worth interrupting your buyer about. A locality-level uncertainty is not, so we don’t.
Where verification is strongest
Delivery point, the top tier: the United States, United Kingdom, Canada, Australia, Germany, France, the Netherlands, plus Denmark, Greece, Turkey, Hong Kong, Singapore, and South Korea.
Premises (building) level: most of the rest of Western and Central Europe, including Austria, Belgium, Italy, Spain, Switzerland, Ireland, Poland, Portugal, Sweden, Finland, and the Czech Republic. A missing apartment number in Vienna won’t be caught the way it would in Chicago, but a wrong street or building will.
Beyond those, coverage spans 250+ countries and territories at varying levels. For destinations where the data only reaches street or city level, verification still runs, it just gets deliberately quiet.
What “quiet” means: we’d rather miss than annoy
When postal data can’t support a confident verdict, the order goes through untouched. No prompt, no tag, no guessing. A false alarm trains your buyers to ignore the prompt that matters, and an aggressive app that flags valid foreign addresses is worse than no app. So the bar for interrupting a buyer scales with how good the data is, and in low-data countries that bar is rarely met.
The same fail-open posture applies when a country’s address format surprises us: accept the order, never block on uncertainty.
What this costs you
It costs nothing extra. Every order is $0.04 on Pro whether it ships to Cleveland or Copenhagen. There’s no international surcharge and no per-country pricing.
One scoping note: the app installs on US-based stores. International here means your international buyers, the roughly one in five orders a typical US store ships abroad. Those are also disproportionately the expensive ones to get wrong, since an international return costs a multiple of a domestic one.
