A2P 10DLC for GoHighLevel Agencies and Sub-Accounts

Why is my GHL SMS not sending?#

Start with the Trust Center inside the sub-account, because the answer is almost always sitting there. If the A2P brand or campaign shows pending, rejected, or was never submitted, the messages aren't being delivered slowly. They aren't being delivered at all. Carriers have blocked unregistered 10DLC traffic outright since February 1, 2025, so a sub-account that skipped registration reaches nobody, and the conversation view keeps looking normal while it happens.

• The usual culprits, roughly in the order support threads surface them:
• The nastier version is the approved campaign that stops delivering anyway. Carriers keep scoring traffic after approval, and the working threshold is a 1% opt-out rate. A sub-account blasting a cold or aged list collects STOPs fast, throughput gets throttled, and the dashboard still shows messages going out. Nobody inside the sub-account can tell a dead lead from a filtered message.

• The A2P campaign was never submitted, so every outbound SMS is silently dropped
• The campaign is still in review, which runs three to ten business days per pass
• The campaign was rejected and the error surfaced in the Trust Center, not in the conversation view where the team is looking
• The registered brand doesn't match the sub-account's actual business, EIN, or website, which fails vetting
• The campaign is approved but carrier filtering is throttling it on opt-out rate or flagged content

How A2P registration actually works inside GoHighLevel#

LC Phone registers at the sub-account level. Each client business submits its own brand (legal name, EIN, website) and its own campaign (use case, sample messages, opt-in description), and HighLevel passes The Campaign Registry's fees through per its published rate card. An agency cannot register one brand and share it across clients: sending multiple businesses' content from one registered identity is exactly the number-sharing pattern carriers block, so a 20-client agency is running 20 separate registrations, 20 vetting reviews, and 20 monthly campaign fees.

• Here's the per-sub-account fee stack, from The Campaign Registry's fee schedule and HighLevel's pass-through rate card. Multiply it by your client count to see the agency-level number.

Why do GHL sub-account campaigns get rejected?#

Because a human reviewer reads the submission cold, with no idea what your agency does, and agency sub-accounts walk in carrying the exact patterns reviewers reject. Vonage's published 10DLC restricted-content guidance names third-party lead generation as flatly prohibited, and a large share of agency use cases are precisely that: texting leads the client bought or the agency generated on the client's behalf.

• The rejection patterns that come up over and over in HighLevel resubmissions:
• The resubmission loop is the real cost. Each rejection adds three to ten business days of review, and The Campaign Registry only swapped its vague rejection codes for granular error codes on March 23, 2026, so campaigns rejected before that were often resubmitted blind. An agency onboarding a new client can burn most of the first month's retainer waiting on a queue.

• Opt-in description that doesn't match the client's live website, or no visible opt-in flow at all
• Sample messages containing URL shorteners or trigger links, which reviewers treat as spam infrastructure
• The registered brand's website showing the agency instead of the client business that owns the number
• Use case described as "customer updates" or "appointment reminders" while the samples read as cold promotion
• Reactivation campaigns over aged or purchased lists, which read as prohibited lead generation
