Transfer your existing tracking numbers, business lines, and toll-free numbers from any carrier or call tracking provider. Keep every number your customers already know while gaining CallScaler's full platform: call flows, AI summaries, recording, and attribution.
CallScaler ports any local or toll-free phone number from any US carrier or call tracking provider. The process is fully managed. You submit the numbers and your carrier invoice. CallScaler handles all paperwork and carrier coordination. Most local ports complete in 7 to 14 business days, toll-free in 3 to 5 days. There is no downtime during transfer, and once complete, numbers immediately gain access to call flows, AI summaries, recording, and full attribution. CallScaler does not charge a port-in fee, while many call tracking providers charge $5 to $25 per number.
Your phone numbers are embedded in your marketing: printed on mailers, listed in Google Business profiles, saved in customer contacts, and running in active ad campaigns. Changing numbers means updating every touchpoint and losing calls from people who have your old number. Porting lets you keep the numbers your audience already knows while gaining CallScaler's full platform for tracking, routing, and intelligence.
Migrating from CallRail, CallTrackingMetrics, Ringba, or another platform? Here is what the switch looks like:
When you submit a port request, CallScaler generates a Letter of Authorization (LOA) and sends it to the losing carrier along with your account verification details. The losing carrier validates the request, schedules a port date, and coordinates with CallScaler's carrier partner (SignalWire) to transfer the number at the scheduled time. The entire process happens without any service interruption to the phone number.
Avoid common delays with these best practices:
Agencies migrating client portfolios can port hundreds of numbers simultaneously. Each number tracks independently in the dashboard, so you can monitor progress across all clients. Because CallScaler numbers start at $0.50 a month on Pro, the cost savings from switching often pay for themselves within the first billing cycle. Many agencies port numbers in phases. Start with one client to validate the process, then migrate the rest.
Once your numbers are live on CallScaler, here is the recommended setup order:
A straightforward four-step process with dedicated support at every stage.
Enter the phone numbers you want to port into CallScaler. Local, toll-free, and vanity numbers are all supported. Upload your latest carrier invoice for verification.
CallScaler submits your port request to the losing carrier. We handle the LOA (Letter of Authorization) and all carrier coordination so you don't have to chase anyone.
Monitor every port request from your dashboard. See status updates, estimated completion dates, and message our team directly from the port conversation thread.
Once the port completes, your numbers are instantly active on CallScaler. Calls route through your configured call flows with recording, attribution, and AI summaries from day one.
