When did 10DLC registration start is a history question that teams ask when they hope a grace period still exists. United States carriers phased 10-Digit Long Code (10DLC) Application-to-Person (A2P) requirements across multiple years. Those start headlines do not create an open exemption for a new program in 2026.
How to Use the History
Use it to explain why older runbooks omit The Campaign Registry (TCR). Do not use it to delay a current filing. T-Mobile, AT&T, and Verizon already filter unregistered A2P on 10DLC. Campaign Service Provider (CSP) banners already print “required.”
Exact first-enforcement dates differed by operator and by use case. Operations calendars should not rebuild around those original dates.
What Started Later
Trust-score effects on throughput, special-use-case operator review, and tighter SHAFT enforcement continued after the first mandates. A program approved early can still face later policy changes. Monitor, do not freeze.
FAQ
Did 10DLC registration start with an FCC order?
The FCC enforces the Telephone Consumer Protection Act (TCPA). 10DLC start dates were carrier and industry-registry events.
