Lob.com US Verifications API

Validate, automatically correct, and standardize the addresses in your address book based on USPS's Coding Accuracy Support System (CASS). back to top ## US Verifications Test Env When verifying US addresses, you'll likely want to test against a wide array of addresses to ensure you're handling responses correctly. With your test API key, requests that use specific values for `address` or `primary_line` and (if using `primary_line`) an arbitrary five digit number for `zip_code` (e.g. "11111") let you explore the responses to many types of addresses: ADDRESS TYPE FOR SAMPLE RESPONSE DELIVERABILITY SET primary_line OR address TO Commercial highrise deliverable commercial highrise Residential highrise deliverable residential highrise Residential house deliverable residential house PO Box deliverable po box Rural route deliverable rural route Puerty Rico address w/ urbanization deliverable puerto rico Military address deliverable military Department of state deliverable department of state Generic deliverable deliverable deliverable Missing a suite number deliverable_missing_unit missing unit Suite number doesn't exist deliverable_incorrect_unit incorrect unit Residential house with unnecessary suite number deliverable_unnecessary_unit unnecessary unit Undeliverable and block matched undeliverable undeliverable block match Undeliverable and no block matched undeliverable undeliverable no match See the `test` request & response examples under [US Verification Examples](#operation/us_verification) within the "Verify a US or US territory address" section in US Verifications. You can rely on the response from these examples generally matching the response you'd see in the live environment with an address of that type (excluding the `recipient` field). The test API key does not perform any verification, automatic correction, or standardization for addresses. If you wish to try these features out, use our live demo or the free plan (see our pricing for details). back to top
