What PostGrid Address Verification is
PostGrid Address Verification checks, autocompletes, standardizes and enriches addresses for delivery across the U.S., Canada and 245+ countries and territories. It accepts structured fields, single-line freeform text and incomplete entries, with real-time verification against postal data. The international service supports CSV batch processing for up to one million addresses and can add geographic coordinates with rooftop-level accuracy. It supports non-Latin scripts, including Chinese, Arabic, Japanese and Korean, and converts these to standardized Roman scripts. Named integrations include Salesforce, Stripe, Dynamics 365, Shopify and Zapier. PostGrid offers API and SDK options, a no-code dashboard and a self-hosted option. Each verification, autocomplete or standardization request counts as one lookup; charges apply for use above a plan’s monthly allowance. Standard Essential costs $18 a month, billed yearly, and includes 2,000 U.S. and Canada lookups per month; additional lookups cost $0.02 each. Test API keys and 500 free lookup credits are available, while a separate bulk service page describes 100 free lookups.
