For a GoHighLevel agency, A2P 10DLC isn't a one-off task. Every US client needs their own registration, every rejection delays a launch, and every unregistered account is a support ticket waiting to happen. Here's how to handle A2P across many sub-accounts without it becoming a bottleneck.
The rule that shapes everything: one brand per business
An A2P brand represents one legal business. You can't register your agency once and cover all your clients: each client sub-account needs its own brand, tied to that client's legal name and tax ID, plus a campaign for what they send.
Clients without an EIN can use the sole proprietor option, which has much lower sending limits. It's fine for a very small business, but plan to move them to a standard brand once they have an EIN.
Collect the right information at onboarding
Most delays come from chasing clients for details. Ask for all of this upfront:
- Exact legal business name, as on the EIN or state registration
- EIN, business type and registered address (not a PO Box)
- Website URL on the client's own domain
- An authorised contact's name, email and mobile number for verification
- What they'll text: reminders, follow-ups, marketing or all of these
Use each client's own email and phone for their registration, not yours. The registry limits how many registrations one email or phone number can be used for, so agencies that reuse their own details hit walls quickly.
Standardise the compliance pages
The opt-in form, privacy policy and terms are where most rejections come from. For every client:
- An opt-in form with an optional, unticked SMS checkbox and complete consent wording
- A privacy policy with the SMS "no sharing" clause
- Terms of service with an SMS section
Put these into your niche snapshots as templates (see my snapshots guide), then fill in each client's details. The exact wording that passes is in my A2P registration guide.
Track every registration
With more than a few clients, keep a simple tracker with:
- Client and sub-account
- Brand status and campaign status
- Submission date and any rejection reasons
- Who owns the next step (you or the client)
Check it weekly. Campaign reviews can take several business days, and a forgotten rejection quietly blocks a client's texting for weeks.
Handling rejections efficiently
- Edit and resubmit, don't delete and recreate, because recreating a campaign costs a new vetting fee.
- Fix every listed reason at once, not one at a time.
- Look for patterns: if several clients fail on the same thing, fix the template in your snapshot.

Who pays the fees?
Registration and campaign fees are charged per client account. Most agencies pass them on as part of onboarding or include them in their setup fee. Either way, make it clear in your agreement so it never becomes a surprise.
Launch checklist for each US client
- Information collected and checked against official records
- Compliance pages live on the client's domain
- Brand submitted and approved
- Campaign submitted with matching description, samples and message flow
- Campaign approved and the number attached
- A test text sent and received before any workflows go live
