Registering your brand

You register one brand for every legal business that will send messages — your agency, and one for each managed client. The form lives at /dashboard/messaging/brands.

Required fields

• Legal name — exactly as it appears on the EIN letter or articles of incorporation. No abbreviations unless they are on the legal record.
• DBA / brand name — the public-facing name. This can differ from legal name (e.g. legal "Acme Holdings LLC", DBA "Acme Pizza").
• EIN (or country tax ID) — required for every entity type other than sole proprietor.
• Entity type — see the matrix below.
• Vertical — closest match to what the business actually does. Pick honestly; mismatches between vertical, sample messages, and the live website cause rejection.
• Website — must be live, HTTPS, accessible (no IP allowlisting, no Cloudflare under-attack mode), and contain visible business info, contact info, and a privacy policy.
• Support email — at the brand's domain (avoid Gmail / Yahoo / Outlook freemail addresses unless you are a sole proprietor).
• Support phone — a real number a recipient can call or text for help.
• Address — registered business address; PO boxes accepted only for sole proprietors.

Entity types

• Private for-profit (LLC, Inc., Corp.) — most agencies and clients. Standard EIN-backed verification.
• Publicly traded for-profit — adds a stock ticker field. Filing reviewed against SEC records.
• Non-profit / 501(c) — EIN required; reviewer cross-checks IRS records.
• Government agency — federal, state, or municipal entity.
• Sole proprietor / DBA — no EIN, but a phone-OTP verification step is added. Use only for genuine single-operator businesses; lower throughput cap (typically ~1,000 messages/day) and stricter content review.

Trust score

Once submitted, the brand receives a trust score from TCR. This score is set when the brand is registered and it does not change over time without a re-vetting. Score is driven primarily by:

• Brand footprint — older companies with more public presence score higher.
• Filing quality — fewer discrepancies between filing, website, EIN records, and prior filings.
• Contact reachability — domain emails, working support phones, and HTTPS sites all help.

Score affects throughput. Higher-trust brands get higher message-per-second caps under the same campaign type. If a brand is rejected as Unverified, fix the filing-vs-site discrepancy and resubmit; for some categories, an external re-vetting is available for a fee.

Common first-submission failures

• Website doesn't load or returns a non-200 — the reviewer can't see the business. Get the site live, then resubmit.
• Legal name doesn't match what's on the EIN letter — re-check the IRS letter; spelling and punctuation matter.
• Freemail address on a non-sole-proprietor brand — switch to support@your-brand.com.
• "Coming soon" landing page instead of a real site — TCR rejects placeholder sites; ship at minimum a home, contact, and privacy page first.

Canadian businesses

Telnyx's 10DLC registration accepts Canadian brands through the same form, with two important constraints:

• Sole proprietors based in Canada are not supported. The sole-proprietor verification path uses US-only ID validation, and the only Canadian ID accepted in the EIN field is a Provincial or Federal Corporation Registry number — which unincorporated sole-props don't have. You'll need to incorporate (Ontario Corporation, BC Corporation, federal Corporations Canada, etc.) and resubmit as Private for-profit with your Corporation Number in the EIN field.
• Use your Corporation Number, not your Business Number (BN). Both are 9 digits, but Telnyx specifically wants the Provincial or Federal Corporations Registry number — your CRA Business Number or tax account number will be rejected.

For Canadian brands, set Country to Canada (CA), use the matching province code for State (ON, QC, BC, etc.), and a Canadian postal code in A1A 1A1 format. The EIN-issuing country must also be CA.

Country, state, and postal code must agree

The pre-submission checklist now catches mismatches between your country, state/province, postal/ZIP code, and EIN-issuing country before you submit. A Canadian address with country set to "US", or a US ZIP code with a Canadian province, will be flagged with a specific fix message — instead of returning a cryptic "the request was not well-formed" rejection from the carrier.
