Our verdict on Lob Address Verification
Lob Address Verification is an API service for businesses that need cleaner customer address data across websites, forms, databases, and software workflows. It checks whether mailing addresses are valid and deliverable, then can correct and standardize them. The service covers US and international addresses, with US address autocomplete, bulk verification, reverse geocoding, ZIP lookups, deliverability insights, and address-component data. It is particularly suited to US-focused startups that also need international validation.
Pricing follows a freemium structure. The Developer plan is $0 per month with annual or monthly billing. The Startup plan is $20 per month when billed annually or $25 per month when billed monthly. Business costs $100 per month annually or $120 per month monthly, while Growth costs $390 per month annually or $450 per month monthly. The published plans show a clear entry path from free development access to higher paid tiers. US autocomplete is included with every Address Verification subscription, and the pricing page lists separate US and international verification schedules.
Platform fit is strongest for teams that can work with an API, since Lob supports web and API use and is designed for integration into software workflows. Shopify is the listed integration, while the core feature set centers on API-based validation rather than a broad integration catalog. International verification helps businesses operating across markets, but international autocomplete is not currently available. Choose Lob for address correction, standardization, deliverability checks, and batch validation with a US-first focus; consider another option if international autocomplete or a wider set of integrations is central to the workflow.
