10DLC vs short codes for SMS fundraising.
Compare 10-digit long codes (10DLC) and short codes for nonprofit and political text messaging. Understand registration, volume, deliverability, and compliance considerations.
What is 10DLC?
10DLC (10-digit long code) is a system for sending application-to-person (A2P) text messages through standard 10-digit phone numbers. Unlike traditional long codes used for person-to-person messaging, 10DLC numbers are registered with carriers specifically for business and organizational messaging.
10DLC registration verifies your organization's identity and messaging use case with carriers, which improves deliverability and reduces filtering compared to unregistered sending.
What are short codes?
Short codes are 5- or 6-digit phone numbers used for high-volume A2P messaging. They are provisioned through the CTIA and carriers, and are designed for large-scale campaigns with high throughput requirements.
Short codes have historically been the standard for nonprofit text-to-give campaigns, event messaging, and high-volume fundraising appeals. They offer the highest throughput and strong brand recognition with supporters.
10DLC vs short codes: how they compare.
| Factor | 10DLC | Short Code |
|---|---|---|
| Best fit | Organizations starting out, moderate volume, budget-conscious | High-volume campaigns, text-to-give, enterprise fundraising |
| Typical use case | Donor communications, advocacy alerts, event follow-ups | Mass appeals, Giving Tuesday, text-to-give, live events |
| Setup time | Days to weeks (registration approval) | 8–12 weeks (carrier provisioning) |
| Registration | Required: brand + campaign registration through TCR | Required: CTIA short code application + carrier approval |
| Message volume | Moderate throughput (varies by trust score) | High throughput (100+ messages/second) |
| Brand trust | Standard — supporters see a 10-digit number | High — supporters recognize short, memorable numbers |
| Supporter experience | Standard SMS from a phone number | Short, branded number (e.g., text GIVE to 56789) |
| Compliance | TCPA + 10DLC registration requirements | TCPA + CTIA short code guidelines |
Understanding registration requirements.
Both 10DLC and short code messaging require registration before you can send messages to supporters.
10DLC registration
10DLC registration happens through The Campaign Registry (TCR). Organizations register their brand identity and messaging use case. Approval typically takes days to weeks and determines your throughput limits and trust score.
Short code provisioning
Short codes are provisioned through a CTIA application and carrier approval process. This typically takes 8–12 weeks and includes content review, use case approval, and compliance verification.
Short codes for nonprofit fundraising.
Short codes have been the standard for nonprofit text-to-give campaigns for over a decade. They offer high throughput for live event appeals, branded keyword campaigns (e.g., "Text GIVE to 56789"), and high-volume Giving Tuesday and year-end pushes. For nonprofits with established text-to-give programs or high-volume messaging needs, short codes remain a strong choice.
Short codes for political campaigns.
Political campaigns, PACs, and advocacy organizations use short codes for rapid-response fundraising, GOTV mobilization, and high-volume campaign messaging. Short codes support the throughput needed for time-sensitive political moments — debate nights, deadline pushes, and election-day turnout.

Your choice of sending infrastructure directly affects whether your messages reach supporters' phones. Registered 10DLC numbers have better deliverability than unregistered long codes. Short codes have the highest deliverability rates due to direct carrier relationships and the provisioning process. Both require ongoing compliance with carrier policies to maintain delivery rates. momoGood helps organizations choose the right infrastructure and maintain the sender reputation needed for reliable delivery.
