Genesys Cloud requires registration of 10-digit local code (10DLC) phone numbers for all Application-to-Person (A2P) text messaging to comply with US and Canadian wireless carrier requirements and prevent message blocking. Implemented in 2021 as part of industry-wide efforts to reduce SMS spam and phishing, this mandatory program applies to all text messaging initiatives using local 10-digit numbers regardless of use case. The registration process requires submission of five mandatory information categories: company details including name, Federal EIN, and address; use case description such as customer service, notifications, or marketing; opt-in method documentation covering channels like website, contract, IVR, agent/phone, or keyword; a screenshot of the actual call-to-action; and the specific 10DLC phone numbers to be registered. All form fields must be completed; incomplete submissions will not be processed. Registration typically requires 1-2 weeks and involves two-factor authentication verification from The Campaign Registry. Wireless carriers enforce daily SMS sending limits to protect network infrastructure and subscribers, with Genesys Cloud managing these rate limits through built-in platform controls that automatically prevent users from exceeding carrier-imposed thresholds. Registration is mandatory for all numbers, whether newly purchased, added to existing accounts, or migrated from other providers. Explicit end-user consent is required for all SMS messaging regardless of use case and must be separated from consent for other communication forms. Genesys Cloud manages wireless carrier fees through a transparent pass-through model, with registration fees and recurring charges passed to customers without markup. Per-message surcharges remain covered under existing per-message pricing with no anticipated increases. Wireless carriers implement varying fee structures based on use case, message direction, and other factors, with detailed pricing information available in the Messaging pricing documentation. This guidance has been regularly updated since its creation in September 2021, with the most recent revision in October 2024.
