What it 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, or incomplete entries and verifies against postal data in real time. Its international service supports CSV batches of 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, with conversion to standardized Roman scripts. Named integrations include Salesforce, Stripe, Dynamics 365, Shopify, and Zapier. Options include APIs and SDKs, a no-code dashboard, and self-hosting. Each verification, autocomplete, or standardization request counts as a lookup; monthly plans impose allowances and additional lookup charges beyond them. Standard Essential costs $18 a month billed yearly and includes 2,000 U.S. and Canada lookups monthly, with additional lookups at $0.02 each. Test API keys and 500 free lookup credits are available; a separate bulk verification service page describes 100 free lookups. The product page lists security and compliance provisions including HIPAA, PIPEDA, GDPR, SOC 2 Type 2, and PCI-DSS.
