Carrier registration
Business texts from ordinary 10-digit numbers in the US go through a registration system usually called 10DLC. You register your business (the brand) and what you plan to send (the campaign). Carriers review both before your messages are delivered reliably.
- Registration asks for your business details, website, sample messages and how people opt in.
- Your opt-in wording and privacy policy must say how numbers are used and that they are not sold or shared.
- Research stores draw closer review, so sample messages should be plainly about orders and stock.
Consent
| Type of text | What you generally need |
|---|---|
| Order and shipping updates | A clear, recorded opt-in to order texts at checkout, separate from marketing consent, plus STOP to end them |
| Restock alerts they asked for | A clear request for that alert |
| Marketing messages | Written consent, from an unticked box with clear wording, recorded |
Marketing texts without consent can carry large per-message penalties under US law. Keep a record of when and how each person agreed.
What to send, and what gets blocked
- Send: order confirmations, payment reminders, shipping and tracking, restock alerts, replies to questions.
- Avoid: compound names in marketing texts, link shorteners, heavy capitals, and anything about using the product on people.
- Always: your brand name at the start and STOP instructions in the first message.
How Purity handles texting
Purity gives each brand its own phone number, registers it with the carriers, keeps two-way conversations with each customer's record, honors STOP automatically, and checks the wording of the texts you and your automations send.
Common questions
- Do I need to register to send business texts?
- For texting at volume from a standard US number, yes. Unregistered traffic is filtered or blocked by carriers.
- Can I text my whole customer list a promotion?
- Only people who gave written consent to marketing texts. Order updates are different from promotions.
