What website does Sinch need for 10DLC registration?

Sinch describes 10DLC as a standard-looking 10-digit business number approved by US carriers for application-to-person texting. To use one, you register your brand, then your campaign, then link your numbers. Your website and its policy pages are part of the campaign step.

10DLC Site is not affiliated with or endorsed by Sinch. Provider names are used only to describe where information goes. This page describes the flow as documented at the time of writing (Updated September 2026). Screens change, so follow what you see in your account.

Where do the website URLs go in Sinch's registration?

Here are the steps Sinch describes:

1. Register your brand with The Campaign Registry. Give your company name, tax ID, and contact details. Sinch says these must be 100% accurate.
2. Register your campaign in the Sinch Customer Dashboard. Add your privacy policy link, terms link, website, description, and opt-in and opt-out details.
3. Add sample messages, including your HELP and STOP responses.
4. Buy or port numbers and link them to the campaign.

What does Sinch check on your website?

Sinch's public overview does not list website review rules in detail. The Campaign Registry and CTIA set a shared baseline that applies no matter which provider you use:

• Privacy policy. CTIA says to display a clear, easy-to-understand privacy policy with clearly labeled links, and to reference it from your call-to-action.
• Terms. TCR says the privacy and terms link fields are optional in TCR itself, but a compliant privacy policy and compliant terms are required.
• Clear call-to-action. CTIA says it should describe the program, name who is sending, explain opt-in and any fees, and cover how to opt out and get help.
• No buried consent. CTIA says opt-in details should not be hidden in terms and conditions.
• Identifiable links. CTIA says websites linked from messages should clearly identify the owner and include contact information, such as a postal mailing address.
• Opt-in and help. TCR's campaign form asks for opt-out and help messages, with STOP and HELP keywords.

What are common Sinch rejections tied to the website?

Sinch's public blog does not list specific rejection reasons or codes for websites, so this guide does not name any. Rejections across providers often trace back to the same website problems. Our rejection pages explain each one:

• Website does not match brand
• Privacy policy missing SMS language
• Missing SMS terms
• Opt-in not verifiable
• Website not accessible

If your campaign is rejected, read the reason in your dashboard and fix that item before you resubmit.

How do I get a website that passes Sinch review?

Use this checklist before you submit:

1. The site is live and matches the brand you registered. See brand name match.
2. It has a clear privacy policy. See privacy policy.
3. It has SMS terms. See SMS terms.
4. It has an opt-in form with clear disclosure text. See opt-in form.
5. It shows your contact details. See business contact info.

10DLC Site builds these pages and gives you the exact URLs to paste into Sinch: homepage, privacy policy, terms, and opt-in page. You still submit the campaign yourself, and carriers make the final decision. The any-provider guide covers the full field model.
