Essential requirements for porting numbers to Telnyx, including LOA and invoice details. See Telnyx guidance and requirements.

Porting Requirements

Before submitting a port request to Telnyx, ensure you have the required documents. This guide covers what you need and why each document matters.

Letter of Authorization (LOA)

The LOA is a legal document that gives Telnyx permission to request a port on your behalf.

LOA Requirements

  • Signer: Must be the authorized person on the account with the losing carrier
  • Numbers: ALL numbers being ported must be listed
  • Information: End user name and service address

Important: We cannot process a port request without a valid LOA.

Invoice or Bill

An invoice proves that the end user porting the numbers is the rightful owner.

Invoice Requirements

  • Must be from your current carrier (the losing carrier)
  • Must be within the last 30 days
  • Should show the telephone numbers being ported (if possible)

What if Your Invoice Doesn't List the Numbers?

If your invoice doesn't show the telephone numbers, provide ONE of these alternatives:

CSRCustomer Service Record from your current carrier listing the numbers
Other ProofContact porting@telnyx.com to discuss options

Customer Service Record (CSR)

A CSR is an official record from your current carrier that contains your account details.

What's on a CSR?

  • Account holder name (exactly as on file)
  • Service address
  • Billing Telephone Number (BTN)
  • List of telephone numbers
  • Current carrier information

Is a CSR Required?

No, but it's highly recommended.

A CSR helps ensure your LOA information matches exactly what the losing carrier has on file — preventing rejections due to mismatched data.

See Obtaining a CSR From Your Carrier for instructions.
