PostGrid Verify is an API that allows you to autocomplete, verify, and standardize addresses in real-time, supporting both individual and batch address verification.
Tools
Autocomplete Address
Tool to autocomplete a partially specified US or Canada address. Retrieves complete verified address including full postal code. Uses 1 lookup per request.
Autocomplete International Address
Tool to retrieve complete verified international address data using an ID from the preview endpoint. Use when you have an address ID from the preview step and need the full address details.
Get Autocomplete Previews
Tool to get previews of autocompleted US and Canadian addresses. Returns partial address data (line1, city, first 3 digits of postal code) without using any lookups. Use when you need quick autocomplete suggestions for address input.
Get International Autocomplete Previews
Tool to get previews of autocompleted international addresses. Results are biased based on your current IP address unless disabled.
