When you port your number to Telnyx, your current carrier may require a PIN, passcode, See Telnyx guidance and requirements.
What is a Porting PIN?
When you port your number to Telnyx, your current carrier may require a PIN, passcode, or transfer code to authorize the move. This is a security feature — it prevents unauthorized number transfers.
⚠️ Important: This is NOT your carrier account password or login PIN. It's a separate code specifically for number porting.
Why Does This Matter?
If the PIN doesn't match your carrier's records, your port will be rejected with PASSCODE_PIN_INVALID. This is the #1 cause of porting delays — but it's always fixable.

Bandwidth / Wholesale Carriers

CLEC / Regional Carriers

Tips
- Your carrier may have a default PIN (often the last 4 digits of your account number or phone number)
- Some carriers generate a new PIN each time — don't use an old one
- If your port keeps getting rejected, ask the carrier to verify what PIN they have on file rather than guessing
