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.
Required Documents Overview
Document | Purpose | Requirements |
Letter of Authorization (LOA) | Authorizes Telnyx to request the port | Required for ALL ports |
Invoice or Bill | Proves ownership of the numbers | Required (alternatives available) |
CSR (optional) | Verifies account details | Recommended, not required |
Letter of Authorization (LOA)
The LOA is a legal document that gives Telnyx permission to request a port on your behalf.
LOA Requirements
Signature: Wet signature or valid electronic signature (DocuSign, Adobe Sign, etc.)
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
Date: Must be signed within the last 90 days
Toll-Free LOA Requirements
For toll-free numbers, the LOA must include:
"Port to RespOrg QIT02"

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:
Alternative | Description |
Portal Screenshot | Screenshot from your current carrier's portal showing the numbers on your account |
CSR | Customer Service Record from your current carrier listing the numbers |
Other Proof | Contact 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.
Document Validity Periods
Document | Maximum Age |
LOA (signature date) | 90 days |
Invoice/Bill | 30 days |
CSR | No strict limit, but recent is better |
Common Rejection Reasons
Ensure your documents are complete to avoid these common issues:
Issue | How to Prevent |
LOA not signed | Ensure authorized person signs the LOA |
Signature too old | Sign within the last 90 days |
Name mismatch | Use exact name from CSR or carrier records |
Address mismatch | Use service address, not billing address |
Missing invoice | Upload a recent bill or acceptable alternative |
Numbers not listed on LOA | Include ALL numbers you want to port |
