A signed Letter of Authorization
The LOA gives your new provider permission to request the numbers on your behalf. It has to be signed by someone authorized on the account, with the business name spelled exactly as your current carrier has it.
Number Porting
Business Phone Number Porting Without the Downtime
Switching phone systems should not mean risking the numbers your customers already call. Velocity Phone Systems ports your existing business numbers onto your new platform and manages every step, so the transition is planned, controlled, and quiet.
We do not port and pray. We gather the right information up front, file a clean order with your current carrier, confirm the numbers are live on the new system, and only then cut over. One team owns the design, the port, the install, and the support.
How number porting actually works
Porting moves your existing phone numbers from your current carrier to your new provider. The mechanics are standardized, but the details have to match exactly. Here is what the process needs.
Account and billing details that match
Your current account number, service address, and any billing PIN have to match the carrier's records. A recent bill is the easiest way to capture all of it correctly the first time.
A confirmed FOC date
Once the order is accepted, the losing carrier issues a Firm Order Commitment date, the day the numbers are scheduled to move. We plan the cutover around that date instead of guessing.
Realistic timelines, and what slows them down
Porting is rarely instant. A clean single-line port can move quickly, while larger or more complex orders take longer. We give you a realistic range for your situation instead of a promise we cannot keep.
Typical ranges by complexity
A clean local number often ports within days to a couple of weeks, while multi-line, multi-location, and toll-free orders generally take longer. Carrier workload and order accuracy both move the date.
The usual causes of delay
Most rejections come from mismatched account information, an old service address, an unpaid balance, a pending order, or a contract still in force with the current carrier. Getting these right up front prevents resubmissions.
Toll-free and complex ports
Toll-free numbers route through a separate system and can follow a different schedule than geographic numbers. Ports that span multiple carriers or locations need extra coordination, which we manage for you.
Porting without downtime
The fear with any port is a window where calls go nowhere. Our job is to remove that window. We design the cutover so your old service keeps working until the new one is proven.
Parallel run and temporary forwarding
Where it helps, we stand up the new system alongside the old one and use temporary forwarding so calls keep landing while everything is configured and tested.
Port first, then cut over
We complete provisioning on the new platform before the FOC date, so the moment the numbers move they already have a home, with greetings, routing, and extensions ready to answer.
Verify before we disconnect anything
We place live inbound and outbound test calls and confirm the numbers work on the new system before old services are released. We never port and immediately disconnect on faith.
What you can port, kept correct
Most business numbers can move, but not everything behaves the same way. We confirm what is portable, what to keep, and what needs special handling, then make sure the details that matter stay right.
Geographic numbers, DIDs, and toll-free
Local main lines, individual direct-dial (DID) numbers, and toll-free numbers can generally be ported. We help you decide which published and internal numbers to bring and which to retire.
Caller ID and E911 stay accurate
Porting a number is separate from setting your outbound caller ID name and your 911 registered location. We configure both on the new system so calls show the right identity and emergency services reach the right address.
One team owns the whole port
The people who design your phone system are the same ones who file the LOA, work the carriers, schedule the FOC, run the cutover, and support you afterward. No handoffs, no finger-pointing.

FAQ
Questions buyers ask before choosing a phone system.
Will my business lose calls or have downtime during the port?
That is the outcome we plan against. Your existing service keeps running until the new system is provisioned and tested, and we verify live calls before releasing the old lines. Scheduled properly, a port happens behind the scenes and your numbers keep ringing.
How long does business number porting take?
It depends on complexity. A single clean local number can move in days to a couple of weeks, while multi-line, multi-location, or toll-free orders take longer. The biggest variable is how cleanly your account information matches your current carrier's records. We give you a realistic range for your specific order.
What information do you need to start a port?
A recent phone bill, your account number and any billing PIN, the exact business name and service address on file, a full list of the numbers to move, and an authorized signer for the Letter of Authorization. The checklist on this page covers everything to gather.
Can I port toll-free and direct-dial (DID) numbers?
Yes. Local geographic numbers, individual DIDs, and toll-free numbers can generally be ported. Toll-free numbers route through a separate system and may follow a different schedule, which we coordinate as part of the order.
Why do ports get delayed or rejected?
Almost always because something does not match the current carrier's records, such as an old service address, a mismatched account number, an unpaid balance, a pending order, or an active contract. We check these before submitting so the order is accepted the first time instead of bouncing back.
Will my caller ID and 911 location be correct after porting?
Yes, because we configure them on the new system as part of the cutover. Moving the number is one step; setting your outbound caller ID name and your registered E911 address is another, and we handle both so callers see the right name and emergency services reach the right place.
