# Change GeoPoints

Use this POST endpoint to submit problem GeoPoints with comments and proposed corrections. This is part of our contribution pipeline to include user input and improve data accuracy.

To ensure your correction can be processed, include the MelissaAddressKey (MAK) identifier for the address, the proposed new coordinates (latitude and longitude), and an explanation in the comments field (e.g., “Moved pin from the highway to the actual building entrance”). Submissions without adequate justification may be discarded.

Upon a successful request you will get an MS01 result code and a successful submission message.

All user contributions enter a queue and are evaluated by our team on a case-by-case basis.

Submitting a correction does not guarantee that it will be approved or integrated into the active dataset.
