If you're registering your business phone number for texting — whether it's appointment reminders, follow-ups, or review requests — you've probably hit a screen asking you to select a campaign type. The options look like a government form written by a telecom lawyer, and picking the wrong one can delay your approval or limit what you're allowed to send.

This guide cuts through the jargon. We'll explain what A2P campaign registration actually is, walk through every campaign type, and tell you exactly which one most service businesses should pick.

What Is A2P Registration and Why Does It Matter?

A2P stands for Application-to-Person messaging — any text message sent from a business platform (like your CRM, scheduling tool, or AI assistant) to a customer's phone. In 2023, the major U.S. carriers (AT&T, T-Mobile, Verizon) started requiring all businesses to register their A2P messaging through a system called 10DLC (10-Digit Long Code).

The goal is to reduce spam. The practical effect for legitimate businesses: you need to register your brand and declare a campaign type that describes how you'll use texting. If you don't register, your messages will be throttled or blocked entirely.

Think of it like getting a business license for texting. The registration tells the carriers: "Here's who we are, here's what we send, and here's proof that people opted in to hear from us." Once approved, your messages get higher throughput and better deliverability.

How Campaign Types Work

When you register, you're asked to categorize your messaging into one or more campaign use cases. Each use case has rules about what kind of content you can send, how recipients must opt in, and what throughput limits you'll get.

The most important thing to understand: your campaign type should match what you actually send. Picking a broader type than necessary doesn't give you more flexibility — it raises scrutiny and can slow down approval. Picking one that's too narrow might mean your legitimate messages get flagged.

Standard Campaign Types: The Full Breakdown

Below is every standard A2P campaign type you'll encounter during registration, explained in plain language with examples relevant to service businesses.

Transactional

Messages triggered by a customer action or an event in your system. These are not marketing — they're operational messages the customer expects to receive.

  • Appointment confirmations and reminders ("Your HVAC tune-up is confirmed for Thursday at 10 AM")
  • Job status updates ("Your technician is on the way — ETA 15 minutes")
  • Invoice and payment confirmations ("Payment of $275 received — thank you!")
  • Estimate follow-ups ("Your estimate for the bathroom remodel is ready to view")

Best for: Most service businesses that primarily text customers about scheduled work, payments, or job updates. This is the most common choice for contractors, home service companies, and field service businesses.

Marketing

Promotional messages designed to drive sales, bookings, or engagement. These require explicit opt-in from the recipient — they must have actively agreed to receive marketing texts from you.

  • Seasonal promotions ("Book your spring AC tune-up this week — $50 off")
  • Referral campaigns ("Refer a neighbor and you both get $25 off your next service")
  • Re-engagement messages to past customers ("It's been 12 months since your last inspection — time to schedule?")
  • Flash sales or limited-time offers

Best for: Businesses that run text-based promotions or special offers. If you only send appointment reminders and job updates, you don't need this — stick with Transactional. If you do both, you may need to register both campaign types.

Mixed / Low Volume Mixed

A catch-all category for businesses that send a combination of transactional and marketing messages from the same number, but at relatively low volume. This is designed for small businesses that don't want to maintain separate campaigns.

  • A plumber who sends appointment reminders AND occasional seasonal specials from the same number
  • A cleaning company that confirms bookings AND sends monthly discount offers
  • Any small business sending fewer than a few thousand messages per month across both categories

Best for: Small service businesses (1–20 employees) that text for multiple purposes but don't send high volume. This is often the simplest, most practical choice for a typical local business. It gives you flexibility without the complexity of managing multiple campaign registrations.

Customer Care

Two-way conversational messaging where the customer initiates or expects ongoing dialogue. Think support tickets via text.

  • Responding to customer questions about their scheduled service
  • Handling warranty or follow-up inquiries via text
  • Back-and-forth coordination ("Can we move my appointment to Friday instead?")
  • Post-service check-ins ("How did everything go with the repair?")

Best for: Businesses that use texting primarily as a two-way communication channel rather than for outbound notifications. If your team regularly has text conversations with customers (vs. sending one-way alerts), this may be a better fit than Transactional.

Account Notifications

Messages about a customer's account status — think of these as system alerts tied to their relationship with your business.

  • Membership renewal reminders ("Your annual maintenance plan renews on April 15")
  • Account balance alerts ("Your account balance is $150 — payment due by March 30")
  • Service plan updates ("Your plan now includes priority scheduling")
  • Login or security notifications (if you have a customer portal)

Best for: Businesses with recurring service plans, memberships, or customer portals that generate account-level notifications. Most small service businesses won't need this as a standalone campaign — Transactional or Mixed usually covers it.

Delivery Notifications

Messages about the physical delivery or arrival of something — a product, a person, or a shipment.

  • "Your technician has arrived at the property"
  • "Your equipment order has shipped — tracking number: XYZ123"
  • "Parts for your repair have arrived — we'll call to schedule installation"

Best for: Businesses with a significant delivery or dispatch component. For most service businesses, these messages fit naturally under Transactional — you typically don't need a separate Delivery Notifications campaign unless delivery updates are your primary texting use case.

Security Alerts

Messages related to account security — verification codes, suspicious activity alerts, password resets.

  • Two-factor authentication codes
  • "A new device logged into your account"
  • Password reset links

Best for: SaaS platforms or businesses with customer-facing login portals. Most service businesses do not need this campaign type.

Public Service Announcement

Non-commercial messages that inform the public about safety, health, or community matters.

  • Weather-related service advisories ("Due to the ice storm, we're rescheduling all outdoor appointments")
  • Community safety alerts
  • Public health notifications

Best for: Government agencies, nonprofits, or utilities. Service businesses rarely need this — if you occasionally send weather-related updates, they fit fine under your existing Transactional or Mixed campaign.

Polling and Voting

Messages that solicit opinions, votes, or survey responses.

  • Customer satisfaction surveys ("How would you rate your service today? Reply 1-5")
  • Feedback requests after a completed job
  • Net promoter score surveys

Best for: Businesses whose primary texting use case is gathering feedback. If you send occasional post-service surveys alongside appointment reminders, your Mixed or Transactional campaign already covers that — no need for a separate Polling campaign.

Charity / Fundraising

Messages soliciting donations or promoting fundraising events for registered nonprofits.

Best for: Registered 501(c)(3) organizations only. Not applicable to service businesses.

Political

Campaign messaging related to political candidates, ballot measures, or advocacy. Requires strict compliance with election communication laws.

Best for: Political organizations and advocacy groups. Not applicable to service businesses.

Which Campaign Type Should Your Service Business Pick?

Here's the decision framework we recommend for most local service businesses:

  1. If you only send appointment reminders, job updates, and payment confirmations → choose Transactional.
  2. If you send a mix of operational texts AND occasional promotions or re-engagement campaigns → choose Mixed / Low Volume Mixed. This is the most common and practical choice for small businesses.
  3. If you primarily run text-based marketing campaigns (promotions, offers, drip sequences) → choose Marketing.
  4. If your texting is mostly two-way conversations with customers → choose Customer Care.
  5. If you're unsure, start with Mixed. It covers the broadest range of legitimate use cases for a small business and is the easiest to get approved.

Tips for Getting Your A2P Registration Approved

Choosing the right campaign type is step one. Here are practical tips to avoid delays and rejections during the registration process:

  • Make sure your business name and EIN match exactly — carriers cross-reference with public records. Even small mismatches ("LLC" vs "L.L.C.") can trigger a manual review.
  • Write sample messages that match your campaign type. If you picked Transactional, don't include promotional language in your samples. If you picked Marketing, make sure your samples include opt-out language.
  • Every campaign must include opt-out instructions. The standard is "Reply STOP to unsubscribe." Include this in your sample messages.
  • Describe your opt-in process clearly. How do customers agree to receive texts from you? Website form, verbal consent during booking, checkbox on an intake form — spell it out.
  • Have a working website. Carriers check that your business URL is live and matches your registration details. A placeholder or broken site will slow you down.
  • Keep your message volume realistic. Don't claim you'll send 50,000 messages per month if you have 200 customers. Overstating volume raises flags.

What Happens After Registration?

Once your campaign is approved, your messages will be sent with full carrier trust — meaning higher throughput, better deliverability, and no throttling. Most registrations are approved within a few business days, though some require manual review and can take up to two weeks.

If your registration is rejected, you'll typically get a reason code. The most common issues are:

  • Business information mismatch (name or EIN doesn't match public records)
  • Insufficient opt-in description
  • Sample messages don't match the declared campaign type
  • Website is down or doesn't match the registered business

Fix the issue, resubmit, and you'll usually be approved on the second attempt.

Frequently Asked Questions

Can I register for multiple campaign types?

Yes — you can register multiple campaigns under the same brand. For example, you might have a Transactional campaign for appointment reminders and a Marketing campaign for promotional offers. However, most small businesses find that a single Mixed campaign covers everything they need. Adding more campaigns increases complexity and cost without much benefit unless your volume is high or your use cases are clearly distinct.

What if I pick the wrong campaign type?

It's not the end of the world. You can update your campaign registration or create a new one. The risk of picking the wrong type is mainly delay — your registration might get rejected if your sample messages don't match your declared use case, and you'll need to resubmit. It won't result in fines or permanent penalties for an honest mistake.

Do I need A2P registration if I'm just texting my own customers?

Yes. A2P registration applies to any business-to-consumer text messaging sent through an application or platform — regardless of whether the recipient is an existing customer. If you're sending texts through your CRM, scheduling software, or any automated system, you need to be registered. The only exception is true person-to-person texting from your personal phone with no automation involved.

How much does A2P registration cost?

The Campaign Registry (TCR) charges a one-time brand registration fee (typically $4) and a monthly campaign fee (typically $10/month per campaign for standard use cases). Your messaging platform may also charge its own fees on top of TCR costs. These fees are minimal compared to the cost of having your messages blocked — a single missed appointment because a confirmation text didn't deliver costs more than a year of registration fees.
