Number porting
Number porting is the process of moving an existing phone number from one provider to another while keeping the number itself. In the US and Canada, the right to port is protected by regulation.

A port is a coordinated handover. You ask the gaining provider to take the number; they submit a request to the losing provider containing details that must match the existing account exactly — the account number, the billing name and address as the old provider has them, and usually a port-out PIN you generate before starting. The losing provider validates, and on an agreed date the number's routing is repointed. Regulators require providers to allow porting, which is why a refusal is nearly always a paperwork mismatch rather than a genuine block.
Most failures are mundane. The billing address on file is an old one. The account is in a business name but the request used a personal one. The port-out PIN was never generated, or has expired. The account was closed before the port completed, which releases the number back into inventory and can make it unrecoverable. That last one is the costly mistake: never cancel the old service until the port has finished.
Timelines vary by number type. Simple wireless ports can complete quickly; landline and business ports involving multiple numbers take longer and are scheduled rather than immediate. Toll-free numbers follow their own process. Expect the switch to be measured in business days and plan the cutover for a period when a brief interruption would not be damaging.
When this matters
Porting matters when a number carries accumulated value — it is on your vehicles, your signage, your listings, and in your customers' phones. Where the number has no such history, taking a new one is faster and avoids the failure modes entirely. The decision is really about how much recognition the existing number has earned.
How VeraDial relates
How this fits with VeraDial
VeraDial issues new numbers rather than porting existing ones
VeraDial provisions a new US or Canadian number on demand when you set up a line; it does not currently port an existing number in. If keeping your current number is essential, that is a genuine reason to look elsewhere — worth knowing before you sign up rather than after.
Forwarding is the bridge
Businesses that want VeraDial's answering without abandoning an established number commonly forward the old line to the new one. Calls keep arriving at the number on your signage and get answered by Vera, and the guides for each carrier's forwarding codes are on the site.
FAQ
How long does number porting take?
It depends on the number type. Straightforward wireless ports can move quickly, while landline and multi-number business ports are scheduled and take longer. Toll-free follows a separate process. Plan for business days rather than hours, and schedule the cutover outside your busiest period.
What is a port-out PIN?
A code you generate with your current provider that authorizes the transfer. It exists to prevent port-out fraud, where someone hijacks a number to intercept verification codes. Most carriers now require one, and a missing or expired PIN is among the most common reasons a port is rejected.
Why do porting requests get rejected?
Almost always a mismatch between the request and the losing provider's records — an outdated billing address, a name that differs from the account holder, a wrong account number, or a missing PIN. Pull up your current bill and copy the details exactly as they appear rather than as you believe them to be.
Can I keep my number if I switch to VeraDial?
Not by porting it in — VeraDial issues a new number rather than transferring an existing one. The common workaround is to forward your existing line to the VeraDial number, so calls to the number your customers already have get answered by Vera. If a direct port is a requirement for you, VeraDial is not the right fit today.
