What is toll-free verification for business texts in Canada?
Toll-free verification is a review that confirms which business is texting from a toll-free number and what kind of texts it sends. A toll-free number that skips it can't text Canadian or US phones. Alert texts to staff need it just like any other business text.

Toll-free verification
In plain English, with what it means for alert texts.
What the verification review checks
The business shares its legal name, address, website and the type of texts it plans to send. It also shows how people agree to get them, which is called opt-in.
Sample messages are part of the file. Reviewers compare them with the stated use, so alarm samples should look like real alarms.
From February 17, 2026, most new submissions also need a business registration number. The rule gives an EIN, the US tax ID for a company, as its example. That comes from an industry rule change (read October 5, 2026).
When unverified numbers started being blocked
The blocking rule took effect on January 31, 2024. From that date, US networks stopped texts from toll-free numbers that were unverified or still pending, as set out in the October 2023 industry notice. A provider's onboarding guide (read October 6, 2026) adds that unverified numbers can't text Canada either.
A blocked alarm looks like silence on the phone. Nothing tells the operator a text was ever sent. The sender's receipt from the network is often the only clue.
A sample alert in a verification file
A Canadian municipal water utility texting pump and chemical alarms to its operators might list a sample like this one.
- Chlorine residual alarm: Welco: [Well 7] Chlorine residual LOW 0.2 mg/L at 6:15 AM. Reply STOP to opt out.
Toll-free verification vs 10DLC registration
Both are checks on who is texting and why. Verification covers toll-free numbers, for texts to Canadian and US phones. 10DLC registration is a US system for US local numbers and splits the check into a brand and a campaign.
Neither one is a promise that every text arrives. A verified number can still have a text stopped by carrier filtering.
How verification affects your alert texts
Welco sends from toll-free numbers it has already verified, so you never file anything with the networks yourself. You sign up with a work email, share your business details and book a short intro call.
Each staff member still joins with their own cellphone and replies YES, which is the opt-in proof reviewers want. The toll-free verification guide has the full process. More number terms are in our SMS alert glossary.
