A few of the specific codes worth knowing before you submit, because they explain rejections that otherwise look arbitrary: code 30925 (missing an unchecked-by-default checkbox specifically for SMS consent, separate from any general terms-of-service checkbox), code 30924 (opt-in language missing the required disclosures: message type, frequency, “message and data rates may apply,” and STOP instructions), code 30893 (sample messages too generic to distinguish a promotional example from a transactional one, or missing bracketed placeholders for merge fields), and code 30920 (a website that’s only a lead-gen form with no surrounding text about what the business actually does). None of these require a new registration, only a specific edit to the flagged field, form, or message sample.

There’s also a distinct category the registry treats as non-negotiable rather than correctable: SHAFT content (sex, hate speech, alcohol, firearms, tobacco) and disallowed use cases like cannabis, payday loans, debt collection, gambling, or crypto get rejected with no resubmission path for that use case at all, regardless of how the messaging is worded. If a rejection reason falls in that range, the fix isn’t better copy, it’s a different campaign category or a different business.

What does A2P 10DLC registration actually verify?

A2P 10DLC (Application-to-Person, 10-Digit Long Code) is the registration system U.S. wireless carriers require before a business can send high-volume text messages from a standard local phone number without it being throttled or blocked as suspected spam. The system, operated through The Campaign Registry (TCR), works in two layers: brand registration verifies the business entity sending the messages, and campaign registration verifies the specific use case, message content, and opt-in process for a given messaging program tied to that brand.

GoHighLevel submits this registration on behalf of sub-accounts through its integration with the registry, but the underlying approval or rejection decision comes from TCR and the carriers, not from GoHighLevel itself. That distinction matters for troubleshooting, because it means a rejection reason reflects registry-level or carrier-level policy, and GoHighLevel’s role is largely to pass along that decision and the reason attached to it.

Why does brand registration get rejected?

Legal business name or EIN mismatch

The most frequent brand-level rejection happens when the legal business name entered doesn’t exactly match what’s registered with the IRS under the provided EIN, or what’s on file with the state where the business is registered. This includes seemingly minor differences: using “GoHighLevel Agency LLC” when the official filing says “GoHighLevel Agency, LLC,” or omitting a suffix like “Inc.” that appears on the EIN registration. The verification process cross-checks these fields against external data sources, and even small formatting differences can cause a failed match.

The fix is straightforward, but it hinges on pulling the name from the right document. The IRS’s CP 575 EIN confirmation letter lists the legal name on its first line only, and that first line is what needs to go into the registration form, not a longer variant that appears elsewhere on the same letter (sole proprietors in particular sometimes see a name format like “ACME LLC [Owner Name] MBR” further down the document, which is not the string TCR expects). If the CP 575 letter isn’t on hand, the IRS’s 147c letter serves the same purpose and can be requested directly from the IRS. It’s also worth checking that the registration used an actual EIN and not a DUNS number: TCR requires an EIN for US-based companies specifically, and a DUNS number in that field produces an unverified status that blocks the registration from progressing at all, distinct from a standard mismatch rejection. A newly issued EIN can also fail verification simply because it hasn’t propagated through the IRS database yet; that typically resolves itself within 30-90 days without any change to the submitted information.

Address mismatch or non-standardized formatting

A registered business address that doesn’t match standard postal formatting, or doesn’t match the address associated with the EIN, can also trigger a rejection. This is especially common for businesses that recently moved, use a registered agent’s address for legal filings but a different address for daily operations, or have inconsistent address formatting across different registrations.

Use the exact address format from official business documentation, and make sure the same address is used consistently if the business has ever changed it in other registrations tied to the same EIN.

Sole proprietor verification limitations

Sole proprietors face a structurally different, and often harder, verification path. Many sole proprietors don’t have a formal EIN and instead operate under a Social Security number, and many don’t have a standardized business address separate from a home address. Because the registry’s verification relies heavily on matching EIN and address records, sole proprietor brands have a thinner verification trail to check against, which results in a meaningfully higher rate of manual review flags and rejections compared to registered LLCs or corporations.

If a sole proprietor registration keeps getting rejected, formalizing the business (obtaining an EIN, even for a sole proprietorship, is possible through the IRS at no cost) often resolves the underlying verification gap rather than repeatedly resubmitting the same thin registration.

Why does campaign registration get rejected?

Vague or generic use-case description

Campaign registration requires describing the specific type of messages the business intends to send. A description like “marketing messages” or “business communications” is too generic for a carrier to classify against the standard campaign categories (such as customer care, marketing, account notifications, or two-factor authentication), and vague descriptions are a common source of rejection specifically because the reviewer can’t confirm the described use case matches the selected campaign type.

The fix is specificity: describe who receives the messages, what triggers a message being sent, and what the message contains. “Appointment reminders and rescheduling links sent to clients who booked through our online scheduler” is concrete enough to classify. “Updates to our customers” is not.

Sample messages that don’t match the campaign type or contain non-compliant content

Campaign registration requires submitting sample messages representative of what will actually be sent. Rejections happen when these samples don’t align with the declared use case, contain content restricted for that campaign type (certain categories, like standard messaging campaigns, have specific restrictions on content such as certain financial services, cannabis-related products, or other regulated categories), or are missing required compliance language such as opt-out instructions.

Review the carrier and TCR content guidelines for the selected campaign type before submitting sample messages, and make sure every sample includes the same opt-out and business-identification language that will actually appear in production messages, since inconsistency between samples and real messages is itself a compliance issue that can surface later even after approval.

Missing or inadequate opt-in documentation

Campaigns require a clear, documented opt-in process describing how contacts consented to receive text messages. A campaign submission that doesn’t clearly explain the opt-in mechanism (a checkbox on a form, a keyword text-in process, a verbal consent captured at signup) or that describes a process inconsistent with how the business actually collects consent, can be rejected or flagged for additional review. This requirement exists because carriers hold registered businesses accountable for the accuracy of their consent claims, not because it’s a formality.

Write the opt-in description as if a carrier reviewer has never seen the business’s actual signup form or intake process, because they haven’t. Name the specific mechanism (“a checkbox below the phone number field on our online booking form, which is unchecked by default and reads ‘I agree to receive appointment reminders by text’”) rather than a general statement like “customers opt in when they sign up.” If the business collects consent multiple ways, at booking, over the phone, or through a paper intake form, describe each one, since a reviewer flags a mismatch between the stated process and what a spot-check of the actual form or script reveals more often than a genuinely absent opt-in process.

What happens to throughput after approval, and can an approved campaign still get throttled?

Getting a brand and campaign approved is a gate, not a finish line, and a second layer of scoring keeps working in the background even after that gate clears. Per HighLevel’s own support documentation on message throughput and trust scores, every Standard Brand goes through an automatic secondary vetting step that assigns it a numeric Trust Score from 0 to 100, generated by a reputation algorithm that reviews the same kind of business-identity information already covered above: EIN records, business type, website, and registration consistency. GoHighLevel’s Phone System submits this vetting automatically; there’s no separate application to fill out for it.

That Trust Score, grouped by HighLevel into three tiers, low, medium, and high, is what actually determines two things: how many messages per second a campaign is allowed to send (its Message Throughput, or MPS), and the separate daily message cap T-Mobile specifically imposes on top of that. A brand that clears standard registration but lands in the lowest trust tier isn’t blocked from sending, but it’s capped at meaningfully lower volume than a brand that scores into the top tier, which is a common source of confusion for an agency that assumes approval alone means unlimited sending capacity.

A second, separate mechanic matters even for a brand that scored well initially: HighLevel’s documentation states that a sub-account’s opt-out rate climbing above 1%, or its error rate (messages sent to landlines or disconnected numbers) exceeding 10%, can trigger automatic throttling or suspension, independent of the original Trust Score. This is the throughput-side version of the compliance monitoring described below: registration approval and a good initial trust score don’t create a permanent exemption from carrier scrutiny. A campaign that was humming along at full throughput can still see its sending capacity cut if list hygiene slips, dead numbers accumulate, or complaint rates creep upward, which is a strong argument for treating list cleanup as an ongoing task rather than a one-time step completed before the first campaign launch.

What’s the actual difference between rejected and permanently blocked?

This distinction causes a lot of unnecessary panic. A standard rejection is a correctable status: the registry or carrier identified a specific problem with the submitted information, and once that problem is fixed, the same brand or campaign can typically be resubmitted and re-evaluated. The vast majority of A2P 10DLC rejections fall into this category, and they’re a normal, expected part of the registration process rather than a sign of a serious compliance problem.

A permanent block is a different and much less common status, generally reserved for confirmed fraudulent registration attempts, repeated serious violations of carrier policy, or patterns strongly associated with spam or scam campaigns. A permanent block on a brand typically means that specific brand registration cannot be resubmitted, and starting over requires registering a new brand, which can also require demonstrating that the underlying issue causing the block has been resolved.

If a rejection reason doesn’t explicitly reference fraud, policy violation, or a permanent designation, treat it as a correctable rejection and work through the specific fix rather than assuming the account is done for. Checking the exact rejection reason text in the GoHighLevel A2P 10DLC dashboard, rather than assuming based on the general “rejected” label, is the right first step whenever this happens.

How do you fix and resubmit a rejected registration?

Start by reading the specific rejection reason provided in GoHighLevel’s A2P 10DLC settings rather than guessing based on the categories above. GoHighLevel surfaces the reason passed back from the registry or carrier, and that reason usually points directly at the field or content that failed review.

For a brand rejection, cross-check every field, legal name, EIN, address, against the exact wording on official business documentation, correct any mismatch, and resubmit. For a campaign rejection, revise the use-case description to be specific and concrete, update sample messages to match both the declared use case and the content restrictions for that campaign type, and confirm the opt-in process description accurately reflects how consent is actually collected. Resubmitting without addressing the specific flagged issue typically produces the same rejection, since the underlying data hasn’t changed.

Once corrections are made, resubmit through the same GoHighLevel A2P 10DLC flow. Processing times vary based on carrier review volume and aren’t controlled by GoHighLevel directly, so checking GoHighLevel’s own help documentation or TCR’s published guidance for current estimates is more reliable than assuming a fixed turnaround.

Where exactly do you find the rejection reason inside GoHighLevel?

Before troubleshooting anything, confirm you’re actually reading the specific rejection reason rather than the general “Rejected” status label, since the two look similar at a glance but only one of them tells you what to fix. Inside a sub-account, the A2P registration status lives under Settings → Phone Numbers → A2P (or a similarly labeled compliance section depending on account version), and clicking into the brand or campaign record itself, not just the summary list view, surfaces the specific error code and description passed back from TCR or the carrier. The summary list often just shows “Rejected” with no detail, which is what leads people to guess at a fix based on the general categories in this guide instead of the actual documented reason for their specific case.

If the detail view doesn’t show a clear reason, GoHighLevel’s support chat can usually pull the raw rejection payload from the account, since the interface doesn’t always surface every field TCR returns. It’s worth doing this before resubmitting a second time, because resubmitting the same information without knowing the specific flagged field just produces the same rejection again, and each cycle costs several days of processing time that a five-minute support chat could have avoided.

Does 10DLC verification work differently from toll-free verification?

Yes, and conflating the two is a common source of confusion when a rejection notice arrives, since GoHighLevel supports both types of number and the verification processes are structurally different. A2P 10DLC, the focus of this guide, registers a standard 10-digit local number through The Campaign Registry and involves the brand/campaign two-layer process described above. Toll-free verification is a separate process specific to toll-free numbers (numbers starting with 800, 888, 877, and similar prefixes), submitted directly to the carriers rather than through TCR, and it uses its own verification form asking about business use case, expected volume, and opt-in process, without the EIN-matching brand layer that drives most 10DLC rejections.

The practical difference that matters most: toll-free verification rejections are almost always about the use-case description and opt-in documentation, the same kind of issue covered in the campaign-rejection section above, since there’s no separate brand-identity layer to fail. A business that’s struggling specifically with EIN or legal-name mismatches on 10DLC brand registration, and needs to start sending sooner than a corrected 10DLC resubmission allows, sometimes uses toll-free verification as a faster interim path, since it sidesteps the brand-identity matching process that’s the single biggest source of 10DLC rejections. It’s not a permanent substitute for most use cases, since sending reputation and long-term deliverability considerations differ between the two number types, but it’s worth knowing the option exists as a bridge rather than assuming a rejected 10DLC brand means no texting capability at all until it’s resolved.

Does approval mean compliance monitoring is over?

Getting a brand and campaign approved clears the registration hurdle, but carriers continue monitoring message content, complaint rates, and sending patterns after approval. A campaign that was approved based on a clean use-case description can still see individual messages filtered or throttled later if actual sending behavior drifts from what was registered, sudden volume spikes, message content that looks promotional when the campaign was registered as transactional, or high opt-out and complaint rates.

This is a separate problem from registration rejection and calls for a different fix: reviewing actual message content and list quality against what was registered, rather than resubmitting a registration that’s already approved. Keeping sending behavior consistent with the registered use case is what keeps an approved campaign delivering reliably over time, not just at the moment of approval.

The bottom line on A2P 10DLC rejections in GoHighLevel

Most A2P 10DLC rejections inside GoHighLevel trace back to a specific, identifiable mismatch, business information that doesn’t match official records at the brand level, or a vague use case, non-compliant samples, or unclear opt-in documentation at the campaign level. Reading the exact rejection reason, fixing that specific issue, and resubmitting resolves the large majority of cases. Reserve real concern for the much rarer permanent block status, which is distinct from a standard rejection and generally tied to fraud or repeated policy violations rather than a fixable data mismatch. If SMS automation is central to how an account’s workflows are supposed to run, it’s worth confirming A2P status is fully resolved before troubleshooting related automation issues covered in the workflow triggering guide, since a workflow that depends on SMS sending can appear broken when the real cause is an unresolved registration rejection upstream.
