What you will need: 

1. The full 10-digit phone number
2. Your preferred carrier name
3. Internet access

Why Check Carrier Portability? 

Carrier portability determines whether a phone carrier can support your phone number on their network.

Even if a carrier supports phone number transfers, they may not support:

• Every rate center ( ▶️ See Rate Center Overview 📖)
• Every geographic region
• Certain wireline numbers
• Rural exchanges

Checking portability before purchasing or porting a number can help avoid:

• Rejected port requests
• Unsupported number issues
• Delays during activation
