An SMS compliance microsite is a purpose-built web property designed to satisfy The Campaign Registry’s online presence requirement for 10DLC brand registration and to centralize the disclosure elements carriers verify during campaign vetting. The term distinguishes this type of page from a general business website — an SMS compliance microsite is structured around the specific documentation that TCR vetting systems and carrier review teams look for: SMS terms and conditions, a CTIA-compliant privacy policy, opt-in mechanism with proper disclosure language, message frequency statements, and HELP and STOP instructions. Standard business websites frequently fail TCR brand vetting not because the business is illegitimate, but because the site was built for customers, not for carrier compliance infrastructure. Understanding what an SMS compliance microsite is — and what distinguishes it from a general web presence — determines whether your brand registration passes or returns error code 1100.
What Is an SMS Compliance Microsite
An SMS compliance microsite is a publicly accessible web property — either a standalone domain, a subdomain of an existing domain, or a dedicated page within an existing website — that contains the full set of documentation TCR and carriers require to verify that a business is operating a legitimate, disclosed A2P SMS program. It functions as a compliance reference document hosted at a stable, publicly reachable URL that can be submitted during brand registration and inspected during campaign vetting.
The defining characteristic of an SMS compliance microsite is its alignment with carrier vetting criteria rather than general audience engagement. A standard business website is written for prospective customers and optimized for conversion. An SMS compliance microsite is structured for carrier review systems that programmatically check for required disclosure elements and for human vetting agents who verify that the brand’s messaging program is fully disclosed and consistent with the registration information submitted.
MyTCRPlus’s Platform Microsite Service provides carrier-friendly compliance microsites with encrypted hosting, uptime monitoring, routine backups, and built-in compliance language templates — deployed specifically to meet the brand registration requirements that standard websites miss.
Why Standard Business Websites Fail TCR Brand Vetting
TCR’s brand registration process requires a website URL. The submitted URL is used by TCR and carrier review systems to verify that the registering entity operates a legitimate business and maintains a public-facing SMS disclosure program. Error code 1100 — “Brand Inconsistencies: no website URL or attachment found” — is one of the most common brand-level rejections. It triggers when no URL is submitted, when the submitted URL returns a broken or non-public page, or when the website exists but the brand name and content are inconsistent with the TCR registration details.
Beyond error code 1100, brand vetting failures occur on compliant-but-incomplete websites. A business may have a functioning website with a generic privacy policy and terms of service that were written for general web use — and still fail vetting because those pages don’t contain the SMS-specific language carriers require. The most common gaps are a privacy policy that doesn’t address mobile data, a terms page that contains no SMS-specific disclosures, and opt-in forms that lack the checkbox placement and disclosure language CTIA standards mandate.
The TCR 101 baseline clarifies the distinction between brand registration (organizational identity verification) and campaign registration (program-level content vetting). Both steps inspect the website URL, and both apply SMS-specific criteria that a general business website wasn’t built to satisfy.
The full list of error codes generated by website compliance failures is documented in the TCR Error Codes & Rejections Hub. Website-related rejections — error 1100 at the brand level, and errors 7100 and 7101 (privacy policy missing or broken URL) at the campaign level — are among the most preventable rejection types and are consistently resolved by deploying a purpose-built SMS compliance microsite.
What an SMS Compliance Microsite Must Contain
An SMS compliance microsite has eight required elements that satisfy TCR brand vetting and CTIA Messaging Principles standards simultaneously. A microsite missing any of these elements risks rejection at brand level, campaign level, or both.
The first element is brand identity. The microsite must display the business name, logo, and contact information in a form that matches the legal entity name submitted during TCR brand registration. Inconsistencies between the displayed business name on the website and the legal name on the brand registration form trigger vetting holds. The physical or registered address should be present and consistent with registration documents.
The second element is an SMS Terms and Conditions page or section. This must be a dedicated, publicly accessible page — not embedded in general Terms of Service — that specifies the SMS program name, types of messages subscribers will receive, approximate message frequency, “Message and data rates may apply” language, opt-out instructions (STOP command), and a HELP instruction with customer care contact information. General terms pages that include a paragraph referencing “electronic communications” do not satisfy this requirement.
The third element is an SMS-specific privacy policy. CTIA’s Messaging Principles and Best Practices require that privacy policies explicitly state that no mobile information will be shared with third parties or affiliates for marketing or promotional purposes. This language must appear in the privacy policy itself — not as a general data protection statement. A standard GDPR-oriented or CCPA-oriented privacy policy that addresses data use broadly but omits this specific mobile data restriction fails carrier vetting at the campaign level under error code 7100 or 7101.
The fourth element is a compliant opt-in mechanism. Any form on the microsite or linked website that collects mobile numbers for SMS programs must include a checkbox or equivalent affirmative action — pre-checked boxes do not satisfy consent requirements — positioned visibly near the phone number field. The disclosure text adjacent to that checkbox must identify the sending brand, describe the message program, state message frequency, reference “Message and data rates may apply,” provide a link to the SMS Terms and Conditions, and provide a link to the Privacy Policy. The opt-in must require active user confirmation.
The SMS Consent Language Validator verifies that opt-in disclosure language meets CTIA and carrier-level consent standards for each campaign type before submission.
The fifth element is a message frequency statement. This can appear within the SMS Terms and Conditions or as a standalone disclosure near the opt-in mechanism. For programs with variable send frequency, the disclosure “Message frequency varies” satisfies the requirement. For programs with predictable cadence, the specific frequency should be stated.
The sixth element is opt-out instruction visibility. STOP instructions must be present in the Terms and Conditions and, where practical, on the opt-in page itself. HELP instructions directing users to a customer care contact must also be accessible.
The seventh element is program description. The microsite should describe the SMS program in plain terms: what messages recipients will receive, what their relationship to the brand is, and what value the program delivers. This program description appears in TCR campaign registration samples and must be consistent with what is stated on the microsite.
The eighth element is operational stability. The microsite URL must be publicly accessible, load without errors, and remain stable after submission. A URL that returns a 404 or redirects to an unrelated domain during vetting will generate the same brand rejection as a missing URL.
When a Business Needs a Dedicated SMS Compliance Microsite vs. Updating an Existing Site
Not every business needs a standalone microsite. Some businesses can satisfy TCR’s online presence requirement by adding the required SMS disclosure pages to an existing website — provided they have editorial control over the privacy policy and terms pages, and the brand name displayed on the site matches the TCR registration.
A dedicated SMS compliance microsite is the correct path in four scenarios. The first is when the business has no existing web presence. Sole proprietors, small service businesses, and businesses that operate exclusively through mobile apps or social media often have no website URL to submit during brand registration. TCR error code 1100 is their first indication that a compliant web presence is mandatory. A dedicated microsite resolves this without requiring the business to build a full company website.
The second scenario is when the business uses a third-party website platform — a template-based site builder, a franchise-provided website, or a marketing agency-managed site — where it does not have direct editorial access to the privacy policy or terms pages. In these situations, attempting to update the privacy policy through the platform’s standard content tools may not produce the specific SMS disclosure language format carriers require. A dedicated microsite hosted independently provides the control needed to meet the exact carrier standard.
The third scenario is multi-location and franchise operations, where each location may require its own web presence for per-location brand registration. A single corporate website does not satisfy the online presence requirement for individual franchisee brands registered under separate EINs. Franchise & Multi-Location SMS Compliance requires a scaled microsite deployment model where each location gets a compliant, independently hosted presence without duplicating the documentation effort across dozens or hundreds of registrations.
The fourth scenario is any business that failed brand vetting on website grounds and needs a rapid resolution. Building or updating a full company website to satisfy compliance requirements can take weeks of development time. A purpose-built SMS compliance microsite can be deployed on a compliance-specific URL in a fraction of that time, with the vetting-critical elements in place from day one.
An SMS compliance microsite is the specific web asset that bridges the gap between a functioning business and a passing TCR brand registration. Its eight required elements — brand identity, SMS Terms and Conditions, mobile-specific privacy policy, compliant opt-in mechanism, message frequency disclosure, opt-out instructions, program description, and operational stability — are the checkpoints that carrier vetting systems inspect systematically. Standard business websites fail those checks not because they misrepresent the business, but because they were built for a different audience. A purpose-built SMS compliance microsite is built for the one audience that controls whether A2P messages get delivered: the carrier vetting infrastructure that stands between your registration and your first approved campaign.
