What happens when I reach my plan's monthly limit?

On the Free plan, requests stop until next month. Every paid plan can keep going with optional overage: turn it on on your Billing page and set a monthly spending cap. Requests past the limit then cost $0.75 per 1,000 on Small, $0.36 on Medium, $0.096 on Large and $0.062 on Business ($0.62, $0.30, $0.08 and $0.052 with yearly billing), until the cap is reached. Overage is off until you turn it on; without it, requests stop at the limit until your quota resets or you upgrade.

What counts as a request?

Most calls count as one request: validate, autocomplete, reverse and match. A search counts one request per postal code found (up to 100 codes per call), radius and polygon searches count 10 requests, and city and state lookups count one request per 10 postal codes returned. Coverage, province and status calls are free, and only successful calls count.

How reliable is the API?

The API has had 99.99% uptime over the last 12 months. You can check the current status any time on the status page.

Where does the data come from?

From the published data of postal operators and government agencies, such as the ONS Postcode Directory in the UK, the US Census Bureau, Statistics Canada, Japan Post and La Poste, completed with GeoNames and OpenStreetMap where no official data is available. We rebuild the database regularly and check every build against the previous one.

Is zipcodestack GDPR compliant?

We process your data in line with the GDPR. zipcodestack is run by Everapi GmbH, an Austrian company, and the API runs on our own servers in Germany. Our Trust Center lists the security measures in place, where your data is kept and every sub-processor.
