When Shippo fits
A checkout or shipping system that wants explicit address-change reasons before creating labels in the same platform.
Check before integrating
The v2 validation request is GET and differs from legacy Address creation with validate=true. A partially_valid result and a recommended correction need a decision, not an automatic success label.
Provider endpoint reference
This is Shippo's documented interface. Its credentials and response format are separate from an All Them APIs account.
GET https://api.goshippo.com/v2/addresses/validate
Authentication: Authorization: ShippoToken token
Inputs: address_line_1, optional address_line_2, city_locality, state_province, postal_code and country_code
Output: original_address, recommended_address, analysis.validation_result, changed_attributes and geodata when available.| Capability | What to expect |
|---|---|
| Validation approach | Validation with a recommended corrected address |
| Coverage boundary | US/global service; confirm country and account coverage |
| Decision signal | Validation value/reasons plus recommendation confidence |
| Apartment/unit handling | Preserve address_line_2 and review changed_attributes |
| Workflow | v2 GET validation; legacy POST validation is different |
| Cost driver | Standalone service entitlement and agreed address volume |
Pricing model and production access
Address Validation access and pricing through sales. Shippo directs Address Validation API pricing and access inquiries to sales. Do not substitute shipping-label fees or assume the standalone v2 service is included in an existing token's entitlement.
For 10,000 address checks, include retries and customer edits, not just completed orders. Count input addresses rather than batch HTTP calls. Compare the same country mix and postal evidence; a geocoding credit and a delivery-verification check do not buy the same result.
Migration notes
Replace legacy street1/city/zip mapping with v2 address_line_1/city_locality/postal_code. Parse analysis.validation_result rather than the legacy validation_results.is_valid field, and keep addresses out of request logs.
Keep provider-specific authentication and response mapping inside an adapter. Preserve source timestamps and identifiers so changing a provider does not silently change the meaning of stored records.
Shippo alternatives
| Alternative | When to evaluate it |
|---|---|
| Shippo vs Google Address Validation | A checkout that needs component-level verdicts and a confirm-or-correct flow inside an existing Google Maps Platform integration. |
| Shippo vs Smarty | US address operations that need to inspect postal and secondary-unit evidence instead of accepting a normalized string as the only result. |
| Shippo vs Loqate | A multinational address-data pipeline that needs country-aware cleansing, multiple input records and explicit quality codes. |
| Shippo vs Geoapify | A location lookup or address-entry flow that can review ambiguous matches and does not require postal delivery-point confirmation. |
| Shippo vs EasyPost | A shipping workflow already using EasyPost that needs verification results before proceeding to shipment and label operations. |
A fair evaluation
- Use provider-approved test fixtures or addresses you have permission to process. Include international formats, accents, rural addresses and unit numbers. Do not generate arbitrary postal addresses or send private customer records without authorization.
- Define expected outcomes for known-good records and approved negative cases before the run. Keep unsupported countries and missing evidence separate from invalid addresses.
- Measure component correction, unit preservation and false rejection separately. A geocoder's building-level match is not confirmation of postal deliverability or of the person living there.
- Record whether the API suggests a correction, confirms a delivery point or merely finds a location. Require customer confirmation when a suggested change could route a parcel elsewhere.
- Count billed address checks, repeated checkout attempts, optional geocoding and batch records. Compare latency and cost per accepted decision on the same country mix. No validation result guarantees a successful future delivery.
