Porting: Best Practices

Porting allows you to move phone numbers from your loser carrier(s) to Trunking.io. This guide provides best practices for service providers to ensure a smooth transition for end users.

Where to go: Porting section of the Trunking.io portal
What you’ll need: CSR from losing provider, LOA, required porting information

Prep Checklist

Before submitting a port request, make sure you have:

• Scope: Confirm if the port is full or partial. Identify numbers that will remain with the losing carrier. Is the current BTN porting?  
• BTN & Account Info: Obtain the Billing Telephone Number, account number, and PIN/passcode (if required).
• CSR & Invoice: Get the Customer Service Record (CSR) and an invoice dated within 30 days from the losing provider. Use CSR values exactly as provided.
• LOA: Ensure the authorized user completes the Letter of Authorization.
• Service Address: Match the CSR details exactly, including street, suite, and ZIP code.
• Dates: Choose a preferred porting window during low-traffic times.
• Routing Ready: Create the destination trunk and test inbound calls to your PBX.

Best Practices

• One BTN per order: Don’t mix BTNs in a single request—this is a common cause of rejection.
• Wireless/VoIP ports: PIN/passcode is often mandatory for porting wireless numbers. You can obtain account information from your current provider via CSR.
• Partial ports: If the current BTN is porting, you will need to identify a new BTN from the remaining numbers to ensure services continues with the remaining inventory.
• Fallback plan: Consider temporary call forwarding or parallel routing during cutover.
• Messaging isn’t automatic: Voice ports do not automatically include SMS/MMS. Confirm messaging hosts and 10DLC mappings.
• Toll-Free vs. Local: Toll-free ports may require RespOrg changes, different documentation and additional requirements.
• E911 & CNAM: Update records after port completion to ensure emergency routing and caller ID accuracy.

Coordination with End Users

• Set expectations: Share the requested window and explain that the final FOC date is dependent on the losing provider.
• Quiet period: Ask customers not to make PBX or system changes once the port has been submitted. This can lead to rejections or additional processing time.

What’s Next

1. Initiate a Port (Port-In Request): Submit the order in the portal.
2. Complete the Port Submission Form: Enter BTN, numbers, and required documents.
3. View Your Port Submission: Verify the summary after submission.
4. Configure DID Routing: Assign numbers to the correct trunk.
