Porting a number out of JustCall means having your new carrier file the port with the details JustCall support provides (CSR, port-out PIN if required, account number), while the JustCall account and the number stay active until the port completes. JustCall documents this precisely: the port is not started from its dashboard, and closing the account early releases the numbers back to the public pool.
JustCall publishes one of the most detailed port-out procedures among business phone providers, with a few quirks worth knowing: an alphanumeric account number some forms reject, an upstream carrier named on the CSR, separate rules for toll-free numbers, a hibernation option that keeps your numbers, and no porting during a free trial. This guide follows that official documentation as checked on November 5, 2026. The general rules of US porting (LOA, CSR, FCC intervals, RespOrg changes) are in our business phone number porting guide.
What does JustCall say about porting out?
JustCall’s help center has a full article on porting out. The principle comes first: the gaining carrier initiates the port, not the JustCall dashboard. Porting is possible at any time, as long as you follow four rules JustCall spells out:
- do not close or delete your JustCall account until the port is fully complete, or the port may fail;
- do not release or delete the number in JustCall while a port is in progress;
- keep the number active, since an inactive or released number causes the port to fail;
- export call logs, SMS records and voicemails first, because you lose access after porting.
The flow is then straightforward. You ask support for the porting details, gather the gaining carrier’s documents, submit everything to the new carrier, JustCall reviews the request against its records and approves it, and the gaining carrier completes the port.
What should you request from JustCall support?
This is where JustCall stands out: its documentation says exactly what it provides. The table below follows JustCall’s list.
| Item | What JustCall says | Note |
|---|---|---|
| Numbers to port | The exact list | Any number left off the LOA stays at JustCall |
| CSR (Customer Service Record) | Carrier name Twilio Inc, 548 Market St #14510, San Francisco, CA 94104 | Twilio is JustCall’s upstream provider |
| Port-out PIN | Only for supported number types and carriers; request it from support | 24 to 48 hours |
| Account number | Alphanumeric (JustCall’s example: 2eafef6f) | Numeric-only alternative if the carrier rejects letters |
| LOA | Not provided by JustCall; the gaining carrier supplies its own | Mobile numbers may need extra forms |
| Regulatory documents | For mobile numbers | Depends on the country |
| Recent phone bill | Requested by the gaining carrier | From your billing section |
Two details save a week. First, the account number: many US porting forms accept digits only. JustCall anticipated this and provides a numeric-only alternative, so ask for both formats in the same message. Second, the number type: JustCall’s FAQ says to select “Local” on the porting form. A wrong category is enough to get the request bounced.
Toll-free numbers
JustCall treats toll-free numbers (800, 888, 877) separately. Per its help center, no port-out PIN is required and CSR details are not maintained for them. You use the account number format JustCall support gives you, and the gaining carrier supplies the toll-free LOA. Behind the scenes, toll-free numbers move by changing the RespOrg rather than through local number portability, which is why the paperwork differs. File them as a separate request from your local numbers.
Numbers outside North America
JustCall’s port-out article is written first for US and Canadian numbers. For a UK or EU number, the gaining carrier will ask for that country’s identifier: in France, for example, the 12-character RIO code assigned to each line. Ask JustCall support in writing which details it can provide for each non-US number, and check that the account holder name and address match what you put on the new carrier’s forms.
The process, step by step
Make sure you are past the trial
JustCall does not allow porting during a trial. If the number was obtained during the trial, subscribe before trying to port it elsewhere.
Export your history
Call logs by date range, reports, contacts, the recordings that matter, voicemails. After the port, access to that data for the number ends.
Request CSR, PIN and account number from support
Through the chat widget in your JustCall dashboard. Ask for the account number in both formats, and list toll-free numbers separately.
Build the file with the gaining carrier
Its LOA, a recent bill, regulatory documents for mobile numbers. Select “Local” as the number type if the form asks.
Let JustCall approve, then cut over
JustCall checks the details against its records and approves. The gaining carrier sets the date. Meanwhile, don’t touch the number or the account.
Test, then close the account
Call every number from an outside cell phone, place an outbound call to check caller ID, send a test text. Only then can the account owner cancel from the Billing section.
How long does it take, and what does it cost?
Timeline. JustCall gives two figures: 24 to 48 hours to share the port-out PIN and CSR details, with possible upstream delays, then 3 to 5 business days for the port once an accurate request is submitted. That fits the FCC framework of one business day for simple ports and four for non-simple ports, which starts only once the request is accepted. In practice, plan one to two weeks end to end if nothing is rejected, and add a week per rejection.
Cost. JustCall’s port-out article mentions no fee. The costs to watch are elsewhere:
- calling credits: JustCall says unused credits are forfeited when the account fully closes, with no refund or transfer. Run them down before the cutover;
- the paid period: if you are on annual billing, align the cutover with your renewal rather than paying for two tools for months.
What happens to calls, texts and recordings?
JustCall is unambiguous: after porting, you lose access to the ported number’s call logs, SMS and voicemails, and a full account closure permanently deletes call logs, SMS history and settings. Porting moves the number, not the data.
What JustCall’s help center lets you export:
- call logs, from the call logs page by date range to an Excel file, and reports from Call Logs or Analytics, delivered by email;
- contacts, from the All Contacts tab, with the file emailed to you;
- recordings, one at a time from the call logs via the recording icon. Access is limited to account owners, admins and members with the right permissions. From JustCall AI conversation views, downloading requires the Team plan or higher and is not supported in the mobile or desktop apps.
Check one setting teams often forget: JustCall can automatically delete recordings older than a retention period you choose, and warns that deleted recordings cannot be recovered. If that setting is on, some of what you expect to keep may already be gone.
For a sales team, the SMS history deserves special care: threads with warm prospects are not always synced to the CRM. Export them, or copy live conversations into contact records, before the cutover. And if you text from a US local number, ask your new provider how A2P 10DLC registration will be handled after the port; our guide to A2P 10DLC and cold texting walks through the process.
The JustCall-specific traps
- Closing the account too early. On closure, every number goes back to the public pool. Support may be able to re-procure one after you resubscribe, but JustCall says recovery is not guaranteed.
- Releasing a number to tidy up. A released or inactive number makes the port fail. Don’t remove any number from the account during the process.
- Sending the alphanumeric account number to a digits-only form. Ask for the numeric version upfront.
- Trying to port during a trial. JustCall doesn’t allow it.
- Leaving credits on the account. They are forfeited on closure.
- Counting on recordings while auto-deletion is on. Check the setting before planning your export.
What if the destination is Skipcall?
Skipcall is an outbound sales phone system: power dialer, parallel dialer up to 4 lines, prerecorded voicemail drop, recording and transcription, SMS sent and received from your numbers, web and mobile apps. Numbers are available in 23 countries: the United States, Canada, the United Kingdom, France, Germany, Spain, Italy, the Netherlands, Belgium, Switzerland, Austria, Luxembourg, Sweden, Finland, Ireland, Portugal, Denmark, Estonia, Romania, Australia, South Africa, Mexico and Brazil. There is no screen in the app for adding a number: any new number is requested from the team through the chat (see our help article on managing phone numbers). Keeping your current number will take a little longer: Skipcall will soon let you port your existing numbers.
What Skipcall does not replace: JustCall is also used for contact center work, with inbound routing and call queues. Skipcall has no IVR, no inbound routing and no queues: each number is assigned to one member, who receives calls, texts and voicemails on it. If your support team runs on JustCall, keep it on a contact center tool and move only your reps’ lines to Skipcall.
To compare the two tools, read our Skipcall vs JustCall comparison, the JustCall alternative page and our JustCall review. On pricing, the Business VoIP plan starts at $25 per user per month billed annually; details are on the pricing page.
One last point before choosing which numbers to port: porting does not clean a number’s reputation. A number labeled as spam at JustCall stays labeled at the new carrier. Our guide to caller ID marked as spam helps decide which numbers are worth keeping.
What to remember
JustCall publishes a clear process, and it comes down to three rules. The gaining carrier starts the port, using the details JustCall support provides within 24 to 48 hours: CSR, PIN where required, account number, in its numeric version if needed. Nothing changes at JustCall during the port: no account closure, no released number, no trial in progress. The data does not follow the number: call logs, texts, voicemails and recordings get exported first, since closure deletes them for good.
Everything else, from FCC intervals to RespOrg changes, is common to all ports and covered in our business phone number porting guide.
