💡 What is it?

• Your current carrier needs specific account details to approve a transfer to NumberBarn. Enter them after checkout, in Carrier credentials on the Numbers page. They must match what your current carrier has on file exactly.

• Incorrect or missing details are the most common cause of delays and rejections

Wireless, Landline, and VoIP Numbers

NumberBarn detects the number type automatically.

📌 Things to Know 

Information Must Match Exactly

Every detail must match your current carrier's records, including the authorized name, address formatting, account number, and PIN. Small differences can cause rejections.

Wireless Numbers Often Require a Special PIN

Many wireless carriers require a Transfer PIN, Porting PIN, or Wireless Transfer PIN. It's different from your regular account PIN and may be issued temporarily just for porting.

If your request is rejected for a PIN mismatch:

• Confirm the correct transfer PIN with your carrier.
• Check whether the PIN expired.
• Confirm your line is unlocked for transfer.
• Click Update My PIN and resubmit. ▶️ See Resolve a Port In Rejection ⚙️
