How do you port a business phone number?

A single number usually ports in a few business days, and larger blocks take longer.

Start with your own setup

Your new provider confirms a cutover date before the numbers move.

Toll-free numbers and copper-tied lines take longer than one local number.

What the source data actually shows

The supplier catalog names these providers. It does not list a monthly price for them. Data as of 2026-10-04.

A TechEstimate is a range. A written proposal is the number you can hold a provider to.

Providers, listed A to Z

These phone systems are alphabetical. This is not a quality ranking.

TechlyScore ranks them for your setup when you compare in real time.

No provider in the source table matches this filter.

What a quote can leave out

The first invoice can add fees that the ad price skipped.

Ask for the all-in total. If they will not say it, that is the answer.

A simple way to decide

Upload your bill if you have one. Or adjust your sliders if you are starting fresh.

You could pay less. You could also pay about the same and save the research time.

The next step on this page is to upload your bill.

Questions people ask

How long does porting take?

A single number usually takes a few business days. Larger blocks, toll-free numbers, and numbers tied to a copper line take longer. Your provider will confirm a date before the cutover.

What is a letter of authorization?

A signed form that tells your current provider you authorise the transfer. It has to match the billing name and address on the account exactly. A mismatch is the most common reason a port is rejected.

Can I port a toll-free number?

Yes, though it runs through a different process than a local number and usually takes longer. Have a recent bill ready, because toll-free ports are matched on the responsible organization record.

Will my phone go down during the port?

It should not. The number switches at a scheduled time, usually within a short window, and calls route to the new service from that point. Keep the old account open until you have confirmed it worked.

Can I port a number to a cell phone?

Yes, but it then behaves like a mobile number and leaves your business phone system. If you want it to ring a mobile and keep the routing, forward it instead of porting it.
