# Frequently Asked Questions (FAQs)

<details>

<summary>How is Maps different from other map services?</summary>

All it takes to share a map with citizens is to log in, upload a list of locations, and click publish. Say goodbye to lengthy AORs or lock-in to external vendors.

Maps also uses OneMap APIs for the most accurate map information.

<summary>I cannot upload my CSV file. Some rows show the error "Add either a 6 digit postal code in the address column or fill in both latitude and longitude columns".</summary>

Some location points are missing a postal code or latitude and longitude coordinates.

Each location point requires at least a postal code (as part of its address) or a set of latitude and longitude coordinates. The street name alone is insufficient.

Fix the flagged rows and upload the file again.

<summary>Why are some of my markers showing as invalid or failing to process?</summary>

The postal code or latitude and longitude coordinates provided may be incorrect.

Please note that Google Sheets or Microsoft Excel might automatically remove leading zeros from postal codes. Before uploading your file to Maps, ensure all postal codes contain the correct six digits, or Maps may not be able to pick up your data, resulting in missing location points.
