For almost every campaign, a registered 10DLC long code is the right answer. It's a normal 10-digit number, cheaper and quicker to provision, built for the back-and-forth that real voter conversations need. Short codes are the expensive, high-throughput option for pure mass blasting, which is rarely what wins.
Why long codes fit campaigns
They support two-way texting, so a voter can reply and a volunteer can answer. They're inexpensive and fast to set up. Registered under 10DLC, they deliver reliably at campaign volume. The conversation, not the blast, is where texting earns turnout.
When a short code makes sense
Very high-volume, one-directional programs with the budget and lead time for a dedicated short code. Most campaigns, especially down-ballot, get better results and lower cost from registered long codes.
Frequently asked questions
Do campaigns use short codes or long codes?
Most use 10DLC long codes, cheaper, faster to set up, and built for two-way conversations. Short codes suit very high-volume one-way blasting, which most campaigns don't need.
What's the difference between a short code and a long code?
A short code is a 5-6 digit high-throughput number for mass blasting; a long code is a standard 10-digit number (registered under 10DLC) that supports two-way texting at lower cost.
