Toll-free verification
When to use a toll-free number, the verification workflow, double opt-in for Canada, and common rejection reasons.
Updated May 6, 20264 min read
Long codes (10-digit local numbers under 10DLC) are the default for most agencies. Toll-free numbers — those starting with 800/833/844/855/866/877/888 — are an alternative with their own verification path.
When to use which
- Long code (10DLC) — best for businesses with a regional or local presence, two-way conversations, and brand-recognizable area codes. Default choice for most agencies.
- Toll-free — best for national businesses, support hotlines, and any case where a single number serves customers across the country. Higher initial throughput than a low-tier 10DLC; verification is per-number, not per-brand.
- Short code — 5-6 digit numbers (e.g. 12345). High volume, fast approval, but expensive. Out of scope for the typical agency workflow.
Toll-free verification workflow
Unlike 10DLC, toll-free verification is per-number. The workflow:
- Submit the verification form on the number after you purchase it.
- Initial review — the platform checks your submission against the carrier's standard requirements. Usually within hours.
- Customer revisions — if anything's off, the status flips to "waiting for you" with the specific reason.
- Carrier review — once we approve, the carriers do final review. Usually 5 business days or less.
- Verified — the number can send. Until verified, deliverability is severely capped or zero.
Required information
- Business name (matching website / email domain) and corporate website with about, contact, and privacy pages.
- A different toll-free number for the contact callback (or a long code).
- Real first/last name of a contact person — not "Support" or "Help Desk".
- Expected message volume.
- Use case category (40+ options including 2FA, fraud alerts, transactional, marketing, polling).
- Use case description with audience and compliance measures.
- Sample messages for each selected use case.
- Opt-in proof — URL with screenshots (web), branded files (paper), call scripts and numbers (verbal), or target keyword (inbound).
Canada — double opt-in
Common rejection reasons
Some are eligible for resubmission with corrections, some are not.
- Not eligible for resubmission — content violations (SHAFT, cannabis), spam / phishing, high-risk fraud, prohibited verticals (loans, gambling, crypto), claims of government / organizational exemption.
- Eligible after fixing — missing or weak age gate, non-HTTPS URL, public URL shortener, inaccessible website, business info that can't be verified, ISV contact instead of end-user contact, insufficient opt-in proof, third-party sharing language in the privacy policy, single number on multiple businesses, insufficient justification for 5+ numbers.
