Porting your business phone numbers to Twilio preserves the brand equity and customer relationships attached to those numbers while giving you access to Twilio's programmable voice and messaging infrastructure. Number porting is governed by carrier regulations, requires documentation that must exactly match losing carrier records, and has typical timelines of 10–15 business days that extend significantly if the request is submitted with any error. Our porting service manages the entire process from eligibility check to confirmed live routing.
What's Included
Port eligibility verification for each number, Letter of Authorization preparation with accurate carrier account details, account number and PIN verification coordination with your current carrier, port request submission to Twilio, carrier coordination throughout the porting window, Twilio number configuration completed before port day so routing is live within minutes of transfer, and emergency rollback planning in case of port rejection are all included in the service.
How It Works
We start by verifying portability for each number, most landlines, mobile numbers, and toll-free numbers in the US, UK, and Canada are eligible, but some VoIP numbers from certain providers have restrictions that require alternative approaches. We collect the required authorization documentation, prepare the Twilio port request with precise detail, submit it, and monitor the port through every carrier processing stage. The Twilio configuration is completed in advance so your numbers route correctly within minutes of completing the transfer.
Who This Is For
Businesses migrating to Twilio from another carrier or CPaaS platform who cannot change their inbound numbers, companies that provisioned new Twilio numbers but want to consolidate their existing business numbers onto the same platform, and any organization where continuity of inbound calling is critical to operations and cannot tolerate a service gap are the right clients for this service.
Why Choose Telphi
Number porting rejections are common when documentation does not exactly match the losing carrier's billing records, a name discrepancy or an account number formatted incorrectly can reject a port and add two weeks to the timeline. We know what documentation each major US, UK, and Canadian carrier requires, how to handle billing name mismatches before submission rather than after rejection, and how to expedite ports when your migration timeline is compressed.
Conclusion
If your business numbers need to move to Twilio, do not risk a failed port that leaves your lines dark during resolution. Book a free consultation with our team to begin the porting eligibility check and get a timeline for your specific numbers.
