Common global address issues
International address support is easy to underestimate. Country-specific postal codes, labels, and phone formats can break assumptions baked into US-only forms.
Postal codes that include letters, spaces, or no standard code
Different labels for state, province, region, county, or governorate
Phone numbers with different country prefixes and local lengths
Address layouts that do not fit a single-line US-style format
Countries to include first
Start with countries that cover diverse formats and current traffic demand, then add more as your product expands.
United States, Canada, United Kingdom, Germany, Singapore, India, Brazil, Mexico, Egypt, and Australia
Countries with numeric and alphanumeric postal code patterns
High-traffic regions from your analytics and Search Console data
Countries where customers actually sign up or purchase
