Why activating SMS takes 2–7 days, in plain language.
Carriers register and review business SMS traffic before letting it through their networks. The process is predictable but takes a few days. Here is what happens, what we file for you, what we need from you, and what each stage looks like.
Your number type changes the timeline.
Local 10-digit numbers (the kind you use for most business lines) go through A2P 10DLC. Toll-free numbers (800/833/844/855/866/877/888) go through Toll-Free Messaging Verification. Same goal — proving your traffic is legitimate before carriers stop filtering it — but two different review pipelines with different timelines.
- A2P 10DLC: brand vetting + campaign registration + carrier review (2–5 business days, typical)
- Toll-Free verification: traffic-profile review by the toll-free aggregator (1–3 business days, typical)
- Pre-approval, both regimes apply rate limits — messages can be filtered or delayed
- Post-approval, full carrier acceptance applies and SMS becomes immediate
Local numbers — the four-stage chain.
A2P 10DLC stands for "Application-to-Person, 10-Digit Long Code." It is the framework US and Canadian carriers use to register business SMS traffic on local numbers. Four stages run mostly in parallel; the long pole is brand vetting plus carrier review.
- TCR (The Campaign Registry) — brand identity registered against your business filing (1–2 business days, mostly automated)
- Brand vetting — third-party verifier confirms the EIN/BN matches the registered business name (24–48 hours)
- Campaign approval — carriers classify the use case and review your sample messages (24–72 hours)
- Carrier filtering — once approved, the major US/CA carriers honor your traffic at full throughput
- End-to-end: typically 2–5 business days for clean submissions
Toll-free numbers — different path, often faster.
Toll-Free Messaging Verification runs through the toll-free aggregator rather than TCR. The review focuses on traffic profile, opt-in evidence, and sample content. End-to-end is usually faster than A2P 10DLC, but the content review is stricter — vague opt-in language is the most common rejection reason.
- Verification request includes traffic profile, opt-in description, and sample messages
- Reviewers check opt-in language, sample content, expected volume, and business identity
- Approval typically 1–3 business days for clean submissions
- Pre-verification, the toll-free aggregator rate-limits and may filter outbound
- Post-verification, full carrier acceptance applies (no separate carrier review step)
The provisioning we run on your behalf.
We file with TCR or the toll-free aggregator under your business identity, register the campaign use case for the standard MeetIndi flow (lead acknowledgment, appointment confirmation, agent follow-up), submit pre-vetted sample-message templates, and pay the per-campaign fees out of the platform fee. You see status inside the dashboard while it runs — no separate portal to log into.
- TCR brand + campaign filings, or Toll-Free verification submission, under your business identity
- Pre-vetted sample-message templates aligned with CASL + TCPA + clean opt-out language
- Carrier escalation channel if a campaign is rejected — we draft the revision, you do not
- Provisioning status surfaced inside the dashboard so you know which stage we are in
- Per-campaign fees included in the platform fee — no separate carrier line item on your invoice
The details we cannot fill in for you.
A few items have to come from your business directly because they are statements about your business identity. We surface a single intake during onboarding, but here is the list up front so you can have it ready and avoid round-trips.
- Legal business name (matches your registered filing exactly — typos here are the #1 brand-vetting rejection)
- EIN (US) or Business Number (CA), matching the legal name on file
- Registered business address that matches your filing
- Authorized signer's name + email — used as the point-of-contact during review
- Three to five sample messages representative of your lead-follow-up flow
- A plain-language opt-in description: how leads consent (verbal during call, written form, web opt-in, etc.)
When the timeline extends past five days.
Most submissions clear in 2–5 business days. Submissions that take longer almost always trace to one of three things: a brand-vetting flag, a carrier-requested sample rewrite, or a use-case re-classification. None of these is a permanent block — each one resolves with a single round-trip.
- Brand-vetting flag — usually a name/EIN mismatch; resolved by re-confirming the exact registered name (24–48 hours)
- Sample-message rewrite — carriers occasionally ask for sharper opt-out language or a clearer business identifier in the message body; we draft the revision and resubmit
- Use-case re-classification — if your traffic profile looks higher-volume than initially filed, the campaign tier moves up; one-time review, then full throughput
- Cross-border restrictions — some Canadian carriers are stricter on cross-border traffic; resolved with a dedicated cross-border campaign filing if your customers span both countries
Throughput limits and how they scale.
Once approved, your campaign has a per-second message rate set by the registered tier. Most low-volume use cases — lead follow-up, appointment confirmation, callback acknowledgment — clear within tier limits comfortably. Higher volume requires a one-time re-tier filing, not a fresh brand vetting.
- Per-campaign throughput is set by the registered tier at filing time
- The dashboard shows your current tier and observed send rate side-by-side
- Hitting a tier limit queues messages — they will still send, just on a short delay
- Re-tiering takes 1–2 business days and does not require re-vetting the brand
- Compliance surfaces (CASL consent log, opt-out keyword handling) are independent of tier and apply at every tier equally
Stage-by-stage timeline at a glance.
Business-day estimates for clean submissions. Real timelines vary by carrier load and submission completeness.
| Stage | Regime | Typical duration | Who acts |
|---|---|---|---|
| TCR brand registration | A2P 10DLC | 1–2 business days | MeetIndi |
| Brand vetting | A2P 10DLC | 24–48 hours | Third-party verifier |
| Campaign approval | A2P 10DLC | 24–72 hours | Carriers |
| Verification submission | Toll-Free | Same business day | MeetIndi |
| Toll-free review | Toll-Free | 1–3 business days | Toll-free aggregator |
| Re-tier (post-approval) | Either | 1–2 business days | Carriers |
CASL consent capture, opt-out keyword handling, and per-tenant consent logging are independent of carrier registration — those apply from day one and continue at every tier equally. See CASL compliance for the structural guarantees.
