Can I automatically block all calls from those area codes?

Yes, you can automatically block calls from specific area codes using your phone's built-in features or third-party apps. Most smartphones allow you to block numbers or create a list of blocked area codes in their settings. For more advanced options, apps like Truecaller or Call Protect can help manage and filter unwanted calls. Keep in mind that blocking area codes may also block legitimate calls, so use this feature with caution.
