Who This Is For / Who It Is Not For
Who this is for: US businesses, compliance owners, marketing ops, and product teams that send or enable A2P SMS and need practical registration, consent, or troubleshooting guidance tied to 10DLC/TCR and TCPA concepts.
Who this is not for: Readers seeking invented fine amounts, guaranteed approval rates, or universal throughput figures; purely P2P consumer texting with no application layer; teams outside US A2P rules who need only foreign-regulator advice.
Short answer: A TCR / A2P 10DLC use case is the Campaign category that tells carriers what kind of messages you send—Marketing, Customer Care, 2FA, Charity, and others. Pick the category that matches your samples and opt-in story. Mislabeling (promo samples on Customer Care) is a common rejection cause. Fees and throughput differ by use case and Brand type—confirm current schedules with your CSP.
Worked example: picking use cases for a mixed program
A gym sends class reminders, billing notices, a monthly newsletter with promotions and occasional surveys. Reminders and billing notices fit Account Notifications; the newsletter is Marketing; surveys fit Polling and Voting. Instead of three campaigns, a gym with modest volume could register one Mixed campaign covering all of them, provided samples show each type and consent covers marketing.
A larger gym chain with high volume registers separate campaigns so each has the throughput and filtering profile that matches its content, and so a problem with the marketing campaign cannot interrupt billing notices.
Why Use Case Selection Matters
When you register a Campaign, the us_app_to_person_usecase field (Twilio’s name) classifies the program. Per Twilio’s collect-business-info guide:
- Available use cases depend on Brand type (Sole Proprietor vs Standard / Low-Volume).
- Use case affects messaging throughput and pricing.
- Description, samples, and message_flow must align with the selected use case.
TCR’s FAQ separately distinguishes standard campaigns (generally available without the extra MNO approval path described for specials) from special campaigns that may need MNO pre/post approval.
Standard Use Cases (Twilio Enumeration)
These appear for Standard Brands in Twilio’s documentation:
| Code / name | Plain-English meaning |
|---|---|
| 2FA | OTPs, password resets, authentication |
| ACCOUNT_NOTIFICATION | Account status alerts, reminders tied to being an account holder |
| CUSTOMER_CARE | Support, account management, customer interaction |
| DELIVERY_NOTIFICATION | Delivery / shipment status |
| FRAUD_ALERT | Potential fraud / spending alerts |
| HIGHER_EDUCATION | College/university education institution campaigns |
| MARKETING | Sales, promos, limited-time offers |
| MIXED | Multiple use cases combined; Twilio notes likely lower throughput and higher cost per message vs single-purpose |
| POLLING_VOTING | Surveys/polling—not political campaigning |
| PUBLIC_SERVICE_ANNOUNCEMENT | PSA-style awareness messages |
| SECURITY_ALERT | Compromised system notifications |
API descriptions are also listed on Twilio’s UsAppToPersonUsecase resource.
Low-Volume Mixed
LOW_VOLUME (Low Volume Mixed): combination use cases with a lower monthly fee than full Mixed (per Twilio) and fixed at the lowest throughput tier. Often used for test/demo or genuinely low traffic. Confirm eligibility and caps with your CSP.
Special Use Cases
Twilio lists special use cases that may qualify for different throughput/fee treatment and may need extra approval:
| Special use case | High-level intent (per Twilio docs) |
|---|---|
| AGENTS_FRANCHISES | Corporate brand with many agents/franchise locations needing localized numbers |
| CHARITY | 501(c)(3) help/fundraising; excludes religious organizations |
| K12_EDUCATION | K-12 virtual learning / school-parent communications |
| PROXY | Proxy/pooled numbers for personalized services without exposing personal lines |
| EMERGENCY | Public safety/health emergency notification services |
| POLITICAL | Organized influence efforts; limited entity types |
| SOCIAL | Public figures/influencers and their communities |
| SWEEPSTAKE | Sweepstakes-related messaging |
TCR FAQ on Agents & Franchises: request should come from the corporate office, not an individual franchisee seeking the use case alone.
Sole Proprietor Use Case
Sole Proprietor Brands use SOLE_PROPRIETOR as the Campaign use case value in Twilio’s model—one Campaign per Sole Proprietor Brand in Twilio’s Brand table. If the business has an EIN, Twilio directs registration as Low-Volume or Standard instead of Sole Proprietor.
How to Choose: A Decision Path
- Are you OTP-only? → 2FA (or consider Verify products that may avoid full 10DLC in some CSP setups—confirm with provider).
- Is content promotional? → Marketing (or Charity/Political if you truly qualify).
- Is it account/support/delivery only? → Prefer a single standard category over Mixed.
- Do you truly need multiple content types on one Campaign? → Mixed or Low-Volume Mixed—with eyes open on throughput/fees.
- Do you qualify for a special path? → Only with documentation (501(c)(3), FEC/527, corporate franchise structure, etc.).
“Types of message” vs use case
People search “message category” meaning either:
- Campaign use case (this article), or
- TCPA content category (marketing vs informational consent standards)
Both matter. Use case is for carrier registration. Consent category is for legal risk. A Customer Care Campaign with promotional copy creates problems in both lanes.
Packaging Tips That Survive Review
- Write the Campaign description so a stranger understands who/whom/why.
- Make samples look like the use case (no “20% off” on Customer Care).
- Document opt-in for that program; Twilio notes verbal consent is generally not sufficient for Marketing use cases in its best-practices blog.
- Declare embedded links/phones honestly and show them in samples.
- Prefer separate Campaigns when Marketing and operational traffic diverge—subject to Brand Campaign limits.

FAQ
What are TCR use case types?
They are Campaign categories declaring the purpose of A2P traffic—Marketing, Customer Care, 2FA, Charity, and others—submitted via your CSP into the 10DLC ecosystem.
Is Mixed always easier?
It can be operationally simpler but Twilio warns of lower throughput and higher per-message cost relative to single-purpose Campaigns. Confirm current commercial terms with your CSP.
Is Polling/Voting for elections?
Twilio describes it for surveys/polling—not political use. Political has its own special use case with eligibility limits.
Can I change use case later?
Usually you register a new Campaign or go through CSP-supported update/resubmit flows. Do not silently send out-of-scope content.
Where do fees live?
On your CSP’s pricing pages—not in this article. Carriers and CSPs mark up and change fees.
