# How to block spam calls from specific area codes and prefixes

The best defense against spoofed calls and neighbor scams

## What are spoofed/neighbor scam calls?

Scammers often use phone numbers with your local area code to trick you into answering. These are called "neighbor scam" or spoofed calls.

## Block by area code on Android

1.  Open Hiya Spam Blocker and go to the **Blocking** tab → **Block List**
    
2.  Tap **+** and select **"Numbers that begin with"**
    
3.  Enter the area code or number prefix you want to block
    

## Block by area code on iPhone

1.  Open Hiya Spam Blocker and tap the **Blocking** tab → **Block List**
    
2.  Tap **+** and select **"Numbers that begin with"**
    
3.  Enter the area code + prefix to block
    

**Free users:** Can set warnings for up to 25 area code/prefix combinations.

**Premium users:** Can fully block up to 25 area code/prefix combinations.

**Note:** On iPhone, Apple does not allow blocking an entire area code alone — you must include at least an area code + prefix.
