The single biggest fear keeping businesses on overpriced phone service is losing the number that's on the sign, the trucks, and ten years of invoices. Here's the reassuring truth: your number belongs to you, not your carrier. FCC rules require your old provider to release it, and a competent new provider handles the entire transfer. Done right, there is zero downtime — calls keep ringing through the whole process.
How porting actually works
Number porting is a carrier-to-carrier handoff called an LNP (Local Number Portability) transfer. Your new provider submits a port request to your old one, the old carrier validates that the account details match, a Firm Order Commitment (FOC) date is scheduled, and on that date the number's routing flips to the new network. Your phones ring on the new system the moment it flips — the industry has done this millions of times.
The realistic timeline
- ▸ Simple ports (one number, standard local carrier): 3–10 business days
- ▸ Multi-number or toll-free ports: 1–3 weeks
- ▸ Ports from cable bundles or resellers: add a few days — the losing carrier's paperwork is slower
- ▸ During the wait: you're already live on temporary numbers, and your old number keeps working normally until the flip
The three mistakes that cause rejections
- ▸ Mismatched account info: the port request must exactly match the name, address, and account number on the losing carrier's record. Pull a copy of your latest bill first — that's the source of truth.
- ▸ Cancelling old service too early: never cancel before the port completes. A cancelled number can be released back to the pool and is much harder to recover.
- ▸ Ignoring the CSR: request a Customer Service Record from your current carrier if anything is uncertain. It shows the exact data the port must match.
What it should cost
Nothing. Some providers still charge $15–$25 per ported number; treat that as a red flag for how the rest of the relationship will go. Talk Is Cheap ports every number free, manages the FOC dates, and keeps you live on temporary numbers so the transition is invisible to your customers.
Your porting checklist
- ▸ Grab a recent bill (account number, authorized name, service address)
- ▸ List every number you own — main lines, fax, toll-free, tracking numbers
- ▸ Sign the new provider's Letter of Authorization (LOA)
- ▸ Keep old service active until the confirmed port date
- ▸ Test inbound and outbound on port day, then cancel the old account
