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. A representative can help you complete the transfer.
