Understanding SMS Sender Types: Short Code vs 10DLC
Not all text messages are transmitted equally. Learn the key differences between enterprise short codes, brand sender IDs, and untrusted virtual numbers.
Alphanumeric Sender ID
Displays an 11-character alphanumeric name instead of a number. Pre-registration is mandated in regulated markets to prevent brand spoofing.
Dedicated Short Code
Vetted through rigorous mobile carrier compliance audits. Reserved for large corporations, banks, and major platforms for 2FA codes.
10DLC (A2P Long Code)
Standard local 10-digit mobile numbers registered under carrier 10DLC programs with approved campaign use cases and verified corporate tax IDs.
Unregistered / Virtual P2P
Disposable VoIP lines leased from virtual trunk providers without corporate verification. Heavily exploited by smishing operators for parcel scams.
