VoIP Number Porting in Florida: Keep Your Business Phone Numbers
VoIP number porting in Florida should not mean gambling with the phone numbers your customers already know. Your numbers belong to your business, not your carrier.
Mynians prepares the port request, files it with your current provider, tracks it to the release date and schedules the cut-over so your existing phones keep ringing until the moment the numbers move. There is no porting charge on your quote.
Nothing is disconnected until the carrier releases the numbers and every line is verified.
Porting is included; taxes and any one-time items are itemized on your written quote.
We file a clean request, monitor it and tell you the release date as soon as it is assigned.
Ported and tested by the same team that builds your system.
How a Number Port Works, Honestly
Number porting follows a carrier-to-carrier process governed by FCC number-portability rules. The steps are the same for every business; the timing is set by the carrier you are leaving. Here is what happens and who controls each part.
Call Review and bill review
We list every number on your bill, including the fax line and the toll-free number people forget, and confirm the account name, account number and service address exactly as your current carrier has them on file.
Build first, port second
Your new system is built, phones are provisioned and the call flow is tested with temporary numbers while your old service stays live. Your team learns the new phones before anything moves.
We file the port request
The request goes to your current carrier with a signed Letter of Authorization and a copy of your bill. Carriers reject LOAs older than 30 days, so we prepare it when the port is ready to file.
Your carrier validates and sets the release date
Your current carrier checks that the business name, address and account number match its records and assigns the release date (the Firm Order Commitment, or FOC, date). If a detail does not match, the port is rejected and we correct and refile — you do not chase anyone.
Common causes of rejection: a legal name that differs from the trade name on the bill, an old suite number, or a billing account number used in place of the service account number.
Cut-over on the release date
Calls begin arriving on the new system on the release date. Your old phones keep working until that moment. We test inbound, outbound, voicemail and E911 on every line the same day, then schedule the cancellation of your old service so nothing is disconnected early.
What Phone Numbers Can Be Ported?
The FCC's local number portability rules require carriers to release numbers when a customer moves to another provider. Most business numbers can be ported to Mynians VoIP.
Local Florida Numbers
Numbers in any Florida area code, whether they are on a traditional carrier, a cable bundle or another VoIP provider today.
For city-specific service and installation details, see our Tampa business VoIP and Miami business VoIP service pages.
- Main business lines
- Direct-dial numbers for staff
- Fax numbers (moved to fax-to-email or T.38)
- Numbers from AT&T, Comcast, Spectrum and other VoIP providers
Toll-Free Numbers
Toll-free numbers (800, 888, 877, 866, 855, 844, 833) follow a separate process through the toll-free number registry, which we coordinate for you.
- Standard and vanity toll-free numbers
- Coordinated with your current toll-free provider
- Usually takes longer than a local port
Vanity and Memorable Numbers
Word-based and repeating-digit numbers port the same way as any other number. Your signage, business cards and website stay accurate.
- Word-based vanity numbers
- Repeating and sequential numbers
- Same process, same no-charge porting
Numbers That May Not Port
A few situations stop or delay a port. We tell you during the bill review if any of your numbers are at risk.
- ✕Numbers already disconnected: a number that has been cancelled is usually returned to the carrier's pool and cannot be recovered.
- ✕Numbers on someone else's account: the account holder must sign the authorization.
- ✕Past-due accounts: carriers can hold a port until the balance is settled.
- ✕Some app-based or temporary numbers: eligibility varies by provider; we check before filing.
Porting From a Specific Provider: What to Expect
Every carrier has its own release process and paperwork habits. The practical differences are about how strictly account details are matched and how release dates are assigned — not about whether the port can happen.
Traditional carriers (AT&T Business and similar)
Legacy carrier accounts often carry two account numbers, multiple service addresses and a term contract. The port itself is routine; the preparation is where delays come from.
What we check before filing:
- Account numbers: billing account versus service account — we confirm which one the carrier's porting desk expects.
- Multiple locations: each address may sit on its own account and need its own request.
- Contract terms: porting does not cancel a term contract; we help you read the early-termination language before deciding on timing.
- Bundled services: numbers bundled with internet can still port, but the internet service may need to be re-papered separately.
Cable providers (Comcast Business, Spectrum Business)
Cable phone service is usually part of a bundle, so the main questions are which numbers are eligible to port on their own and what happens to the internet service you keep. More on switching from Spectrum Business.
Documentation these providers commonly require:
- Letter of Authorization: signed by the account holder; we prepare it with your request.
- A bill from the last 30 days: showing every number being ported.
- Exact address match: suite numbers and abbreviations must match the provider's records.
- Legal business name: a trade name or DBA that differs from the account name can trigger a rejection.
Other VoIP providers (RingCentral, Nextiva and others)
Moving from RingCentral, Nextiva or another cloud provider is usually straightforward: the numbers are already VoIP numbers and the account information is easy to find.
Things to check first:
- Term and renewal dates: annual plans may renew automatically; check the notice period before you file.
- Port-out details: some providers require a port-out PIN or a specific account ID from the portal.
- Call-flow rebuild: auto attendant menus and queues do not move with the numbers; we rebuild them on your new system before the port date.
How We Keep Calls Ringing During the Switch
The question every owner asks is “will my phones go down?” A port done in the right order does not interrupt calls: the old service stays live until the release date, and the new system is built and tested before it.
The Order That Protects Your Calls
Your old system stays active
Throughout the porting process your existing phone service keeps working. Customers call your current numbers and business continues. We never ask you to cancel before the port completes.
We build and test the new system first
While the port request is with your carrier, we install and configure your system: extensions, voicemail, auto attendant, queues and failover rules, tested with temporary numbers and real calls.
Cut-over on the carrier's release date
On the release date the numbers move to the new system. We test every line the same day — inbound, outbound, voicemail and E911 — and stay reachable while your team makes its first calls.
What we control, and what we don't
We control the quality of the request, the order of the work and the testing. The release date is set by the carrier you are leaving, which is why we do not publish a fixed number of days for the port itself.
- Pre-port testing: the whole call flow is tested with temporary numbers before anything moves.
- Team training: staff learn the new phones before the port date.
- Port tracking: we monitor the request and tell you the release date as soon as it is assigned.
- Failover set up before storm season: calls can be rerouted to mobile apps or another site if the office loses power or internet. How failover is configured.

Your old service stays live until the carrier's release date. On that date calls move to the new Mynians system, which was built and tested beforehand. We test every line the same day.
It depends on your current carrier's release process. Clean local ports are often released within days; toll-free numbers, large blocks and accounts with mismatched details take longer. We monitor the request daily and tell you the date as soon as it is assigned. Your system is built while you wait, so the port is never the thing holding up your install.
A complete list of the numbers to move, the account number and business name exactly as they appear on your current bill, the service address on file, a copy of your most recent bill, and a Letter of Authorization signed by the person authorized on the account. We prepare the LOA and check every detail before filing.
Rejections are almost always an account-detail mismatch — a legal name, suite number or account number that differs from the carrier's records. We correct the request and refile. Carriers are required by FCC rules to release numbers to a customer who moves providers; they cannot refuse a valid request.
Yes. Toll-free ports go through the toll-free registry and your current toll-free provider, which we coordinate. They usually take longer than local numbers. There is no porting charge for toll-free numbers either.
There is no porting charge on your Mynians quote. Your current carrier may bill through the release date, and any early-termination fee in your existing contract is between you and that carrier — we help you read the terms before deciding on timing.
No. Cancelling first can release your numbers back to the carrier and make them unrecoverable. Keep the old service active; we schedule the cancellation after the port completes and every line is verified.
