What the Address Validation API does

One call turns a messy user-entered address into verified, structured data.

Verify deliverability

Check that an address actually exists and can receive mail or parcels before you ship, reducing failed deliveries and returns.

Correct and standardize

Fix typos, expand abbreviations, and normalize each address to a consistent format with structured street, city, postal code, and country fields.

Complete missing fields

Infer postal codes, regions, and other missing components from partial input so your records stay clean and queryable.

EU formats, GDPR hosting

Full coverage of European address formats on EU-hosted infrastructure, with no data transfer to the US and full GDPR compliance.

Where teams use address validation

Anywhere a wrong address costs money or time.

Checkout and e-commerce

Validate shipping addresses at checkout to cut failed deliveries, reduce support tickets, and improve conversion with inline correction.

Onboarding and KYC

Standardize customer addresses during sign-up so billing, compliance, and CRM records are accurate from day one.

Logistics and field service

Clean address data before routing so drivers and technicians reach the right location the first time.

Address Validation API FAQ

Common questions about verifying and standardizing addresses.

What is an address validation API?
An address validation API checks whether an address is real, corrects errors, and returns it in a standardized, structured format. It confirms deliverability and fills missing components such as postal code or region, all through a single request.
What is the difference between address validation and address autocomplete?
Autocomplete suggests addresses as a user types to speed up entry. Validation confirms that a completed address exists and is correctly formatted. The MapAtlas Search API and Address Validation API cover both stages, from entry to verification.
Does the Address Validation API support European address formats?
Yes. It covers address formats across European countries, including local postal code rules and administrative divisions, and runs on EU-hosted infrastructure with no transfer of personal data outside the EU.
Is the Address Validation API GDPR compliant?
Yes. All processing runs on EU-hosted infrastructure, addresses are not sold or shared, and the service is designed for GDPR compliance, so you can validate personal addresses without a US data transfer.
Can I validate addresses in bulk?
Yes. You can validate addresses one at a time at checkout or in batches for cleaning an existing database. The API returns structured components and a status for each address so you can flag the ones that need review.
How does address validation reduce failed deliveries?
Most failed deliveries come from typos, missing unit numbers, or wrong postal codes. Validating and correcting the address before you ship means parcels reach the right place the first time, cutting returns and re-delivery costs.
