10DLC
10DLC Overview
10DLC (10-digit long code) is a service offered by the US mobile network operators to explicitly allow application-to-person (A2P) SMS traffic over long code phone numbers. 10DLC numbers are standard US local phone numbers that are 10 digits long, including the area code. 10DLC is designed specifically for commercial A2P messaging.
In addition, businesses can register mixed use cases — a combination of two to five standard use cases — and low-volume mixed use cases, for brands with low throughput requirements.
Standard and mixed-use cases usually require no additional review. There are also special use cases such as 501(c)(3) charity, emergency services, K–12 education, political campaigns, and sweepstakes that may require additional approval, warrant additional fees, or have differences in throughput compared to standard use cases. Plivo does not support registration for special use cases yet.
Plivo now requires customers to register long codes for 10DLC for messaging in the US. Messages sent from numbers that are not associated with registered campaigns will not be delivered.
Benefits
10DLC provides several benefits over alternatives such as unregistered long codes, toll-free numbers, and short codes for messaging campaigns (use cases).- Improved deliverability: Because use cases are preapproved by mobile network operators, messages sent using 10DLC numbers are more likely to reach their intended recipients.
- Cost savings:
- Short code numbers have higher monthly rates than 10DLC numbers. Businesses that can’t afford a short code or don’t send enough messages to warrant paying for one now have a more cost-effective alternative.
- Businesses can use their current regular long codes for 10DLC campaigns. This means that businesses can send more messages from their existing phone numbers without having to pay for new ones.
- High messaging throughput: 10DLC numbers can deliver up to 4,500 transactions per minute per operator, depending on the characteristics of the brand and campaign use case for which a 10DLC number is approved.
- Transparent ecosystem: The registration process detects bad actors, resulting in higher response rates and a reduction in spam texts overall.
- Lower surcharges, less filtering: If you have multiple low-volume use cases, you can register a mixed campaign and get your traffic approved beforehand, which will help you pay lower surcharges. Because your sample messages are already approved, less filtering will be applied to your messages.
Who should use 10DLC?
10DLC is the best phone number choice for most standard use cases, such as delivery notifications and two-factor authentication. They’re also best for businesses that want to have their messages come from familiar local numbers. 10DLC gives businesses the flexibility to create multiple campaigns (one for marketing, one for 2FA, for instance) — and if you have multiple use cases, you can create a mixed campaign. By comparison, toll-free numbers have lower maximum throughput and take slightly longer to get approval for. And while short codes offer higher maximum throughput than 10DLC, they have higher monthly rental costs and one-time setup fees and take several weeks to provision. Can I use long codes without registering them as 10DLC numbers? You must register your long codes if you use them for A2P messaging. Not registering long codes has repercussions that impact your costs and your effectiveness. Carriers can impose fines for using unregistered long codes for A2P traffic. Worse, unregistered traffic is subject to high carrier filtering, which can result in your messages not reaching their destination, wasting the per-message fee you pay for outgoing messages. Ultimately, continued use of unregistered long codes may result in your business losing access to SMS.10DLC specifics: brands and campaigns
