A phone number is not property. It is a registration, and it sits with whoever the carrier lists as the account holder. If that name is your answering service, your VoIP reseller, or the agency that set up call tracking, the number on your lawn signs is theirs. You are borrowing it, and the loan ends when the relationship does.
A port is a name match, not a negotiation
The right to keep your number is real. The CRTC is direct about it: you can keep your phone number when you change phone companies, as long as you stay within your local exchange area, and the provider you are moving to handles the transfer. That right belongs to the subscriber. The whole question is who the carrier believes the subscriber is.
A port clears when the submitted details match what the losing carrier holds. Bandwidth, a carrier that runs these requests daily, states it plainly in its Canadian porting guidance: the account information being submitted must match exactly what the losing carrier has on file. The letter of authorization must be signed by someone the old provider recognizes on that account.
Here is the part that bites Canadian operators. South of the border you can pull a customer service record and read back the exact strings the carrier holds. Bandwidth notes that customer service records are not an available tool in Canada, and that equipment records, the nearest equivalent, come only from Bell and Telus and not for every account. When a Canadian port is rejected on a mismatch, you are often guessing at the spelling that would have cleared it.
Where ownership quietly moves
None of these look like a transfer of control. All of them are one.
- An answering service or leasing call centre that includes a number in the package. It came from their inventory and stays there.
- Call tracking numbers an agency places on your listings and Google Business Profile. Those sit under the agency's name by design, because the agency needs the reporting.
- A VoIP line an office manager set up years ago on a personal card, with a personal email as the authorized contact.
- Toll-free numbers, which move by a change of responsible organization in a shared registry rather than a normal port.
The check
- List every number a renter can reach you on. Signage, Google Business Profile, syndicated listings, voicemail greetings, email signatures, and old leases.
- For each one, find the invoice. Whoever is billed is the account holder of record. If no invoice comes to you, you are not the account holder, whatever their portal calls you.
- Ask each provider, in writing, for the account of record details: legal entity name exactly as spelled, service address exactly as written, billing telephone number, authorized contacts. File it somewhere durable.
- Where a number sits in a vendor's name, ask to move it into an account you own now, while the relationship is good. A vendor mid-renewal is more agreeable than one you have given notice to.
- Add a second authorized contact everywhere. One departed office manager should never be the only signature a carrier will accept.
Why it is worth the afternoon
Almost everything else in your marketing can be swapped quietly. Change your website, your CRM, your photos, and no prospect notices. A phone number is the one asset that has been copied outward for years and cannot be recalled. It is stamped on signs, cached in Google, saved in renters' contacts, written into signed leases. When you lose it, none of those copies update. They keep pointing at a line you no longer answer, or at a queue someone else now runs.
The number is rarely what the dispute is about. It is what turns a routine vendor switch into a fight you cannot afford to lose. Find out whose name is on yours while the answer is still boring.
