Port your business numbers without downtime
Number porting (local number portability, or LNP) means moving your phone number from one carrier to another, and US carriers are legally required to release it. We port your business phone numbers to Dialerportal for you: LOA prepared, carriers coordinated, old line ringing until the moment of cutover.

How number porting works
Four steps from your current carrier to Dialerportal, and your callers never notice a thing.
Submit your LOA and a recent bill
We prepare the Letter of Authorization, you sign it and attach a copy of a recent invoice from your current provider. That's the whole paperwork burden on your side.
We validate with the losing carrier
Before anything is submitted, we check your account number, service address and authorized name against the carrier's records, so the order isn't bounced back for a mismatch.
Your port date is scheduled
The losing carrier confirms a firm port date. Meanwhile we configure your numbers in your new Dialerportal service, ready to answer the instant they arrive.
Cutover with no downtime
On the scheduled date the number transfers to us and calls start flowing to your new setup immediately. Your old line works until that exact moment, so nothing goes dark.
What you need, and what trips ports up
Four pieces of information cover almost every port. Getting them wrong is also the reason most ports get rejected, so we verify each one before the order goes in.
Your porting checklist
- Your account number. Exactly as it appears with your current carrier, not the phone number itself.
- The service address on file. The address your current carrier has on record, which is not always your mailing address.
- An authorized signer. The person named on the account, or someone formally authorized to act on it, signs the LOA.
- A recent invoice. A bill or customer service record from the last 30 days that shows the numbers being ported.
Why ports get rejected, and how we prevent it
- Mismatched service address. The address on the LOA doesn't match the losing carrier's records. We pull the details from your invoice and verify them with you before submitting, so the order matches character for character.
- Outstanding balance or pending orders. Unpaid balances or open change orders on the old account can freeze a port. We flag this up front so you can clear it before the order goes in, instead of discovering it a week later.
- Wrong account number or PIN. Carriers reject ports over a single wrong digit. We confirm the account number and any port-out PIN directly against your bill, and resubmit fast on your behalf if anything still bounces.
Porting is the first step. Land your numbers on a fully managed Cloud PBX, feed them into your own phone system over SIP trunking, or explore the full range of our VoIP services.
Number porting FAQ
The questions businesses ask before moving their numbers.
For most US local numbers, the port completes within 24 to 48 hours after the losing carrier approves the order. Approval itself usually takes a few business days, depending on the carrier. Large multi-number projects and toll-free numbers can take longer, and we give you a firm port date as soon as the carrier confirms it.
