# How to Validate Addresses with ChatGPT

ChatGPT explains what was corrected in each standardized address, helping you understand and fix the underlying data quality issues. It flags low-confidence results with clear explanations of what might be wrong, turning address validation from a pass-fail check into a data quality improvement process.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "Validate this address and return the standardized version" with the address
3. ChatGPT returns the cleaned address and flags any issues
4. Request: "Which of these addresses look invalid?" for a batch check

## Example Prompt

```
Check if this address is valid and give me the properly formatted version: "123 Main St, Apt 4B, springfield". Add the missing state and zip code if you can.
```

## Tips

- ChatGPT can explain what was corrected in the standardized version compared to the original
- Ask it to flag addresses with low confidence separately so you can review them manually
