Pay-As-You-Go Pricing Calculator

Geocodio pricing is increasing on February 1st, 2026. Learn more here.


By default, your usage will be rolled up for the entire month and charged on the first of the following month. (For example, December usage is charged on January 1st.)

You potentially can save money (and have one less expense report to submit every month!) by pre-purchasing credits, which are eligible for volume discounts. Credits do not expire.

Please note, this pricing only applies to our self-serve product, and not our HIPAA/HITECH-compliant Enterprise product.
