Lob Address Verification vs PostPilot

Lob Address Verification checks address data to help determine whether addresses can be delivered. Its APIs validate one address or a batch, and Lob says it can also check and standardize addresses while customers enter them on a website. Results can add delivery and geographic details, including ZIP+4, carrier route, address type, latitude and longitude, plus a confidence score based on its mail delivery data. The product page lists delivery data for more than 240 global territories and USPS CASS certification. Integrations include AV Elements, Shopify Address Cleanser, Airtable Address Cleanser and Zapier; the interactive demo provides examples in cURL, TypeScript, Node, Ruby, Python, PHP, Java, Elixir and C#. Lob says it encrypts data in transit with TLS 1.2+ and at rest with AES-256, and provides automatic redaction and data retention policies. Developer has no subscription fee; listed paid pricing starts at $20/mo (annual). A 30-day Enterprise trial is available for high-volume senders; print and postage are billed separately at discounted Enterprise rates.
