Executive Summary
Accounting firms text clients about appointment reminders, document requests, e-signature links, and filing deadlines. During tax season, volume spikes. US local numbers through practice platforms require A2P 10DLC Brand and Campaign registration. Keep tax marketing (for example, “refund advance promos” from partners) off informational Campaigns unless you have proper marketing consent and packaging.
Short answer: Register 10DLC before tax season. Use care/account Campaigns for reminders and doc requests; Marketing Campaigns for promotional offers. Plan throughput with your CSP—do not assume buying more numbers raises caps.

Seasonal Throughput Planning
Confirm CSP caps early. If volume will exceed Low-Volume bands, discuss Standard Brand and vetting options. TCR FAQ: more numbers ≠ more throughput. Stage sends across days rather than one giant Monday blast when constrained.

Worked example: a CPA firm during tax season
A 12-person CPA firm texts document reminders, appointment confirmations and filing-status updates. Volume spikes from February to April, so it registers a standard brand and an Account Notifications campaign sized for peak season instead of a low-volume campaign it would outgrow. Clients consent through the engagement letter portal with wording that names the firm and describes reminder and status messages.
Templates never include tax amounts, Social Security numbers or refund figures; they direct clients to the secure portal ("Your return is ready to review in the client portal"). The firm avoids sending marketing for advisory services by text, and staff are told never to request documents or payments by SMS, which keeps the program clear of phishing patterns carriers watch for.
