How It Works

1

Enter ZIP Codes

Paste multiple US ZIP codes into the text area. You can separate them by commas, spaces, or new lines.

2

Choose which service level to use for the lookup and adjust the number of concurrent requests. Higher concurrent values mean faster results but may trigger rate limits.

3

Get Results

Click "Find Cities" and the tool will fetch city and state information for each ZIP code.

4

Copy Results

Choose to copy either the full results (ZIP ➜ City, State) or just the city and state names.

Frequently Asked Questions

Is this tool free to use?

Yes, this ZIP Code to City Finder tool is completely free to use with no limitations.

How many ZIP codes can I look up at once?

You can look up multiple ZIP codes at once. However, for best performance, we recommend keeping it under 100 ZIP codes per batch.

Does this work for international postal codes?

Currently, this tool only supports US ZIP codes. Support for international postal codes may be added in the future.

What if a ZIP code is invalid?

If a ZIP code is invalid or not found in the database, it will be marked as "Not found" in the results.

What does the "Concurrent Requests" slider do?

This controls how many ZIP codes are processed simultaneously. Higher values (up to 10) make the process faster but may trigger rate limits. The default value of 3 provides a good balance between speed and reliability.
