# The 'unsupported zip code' error and how to fix it

When activating your SIM card, you can either transfer an existing phone number or get a new number.

##### Getting a New Number

Enter a U.S.-based ZIP code, ideally from a major city. Using an invalid ZIP code will trigger an “*unsupported ZIP code*” error. The area code for your new number is determined by the ZIP code you provide.

If the error persists even with a valid U.S. ZIP code, make sure you’ve entered it correctly and that it corresponds to a U.S. city.

Sometimes, there may be no available numbers in the area code for your chosen location. In this case, try a nearby ZIP code to increase your chances of finding a number.

##### Clear your browser history

If the issue continues after trying multiple ZIP codes, your web browser may be causing the problem. Try using a private/incognito window or clearing your browser history before attempting activation again.

- Transferring an Existing Number
- If you’re transferring a number from another wireless carrier and encounter an error, please [contact customer service](http://redpocket.com/contact-us). A representative can help you complete the transfer.
