What is 10DLC, and why do business texts need it?

Updated November 2026 · JobCatcher

If your business sends texts from a regular 10-digit phone number, US phone carriers want to know who you are first. That registration is called 10DLC, short for "10-digit long code". Skip it and your texts may be blocked or never delivered.

What 10DLC means in plain terms

Carriers like AT&T, T-Mobile and Verizon treat texts from businesses differently from texts between friends. To cut down on spam, they ask businesses to register two things through The Campaign Registry:

Your brand: who is sending the texts.
Your campaign: what kind of texts you send and why, like replies to customers who just called.

Once approved, your number is trusted to send business texts, and delivery is far more reliable.

How long it takes

It varies. Brand checks can be quick, but campaign reviews often take several business days, and longer if anything needs a second look. That's why texting services usually can't switch on the same day you sign up.

Small businesses and sole proprietors

You don't need a big company to register. There's a path for sole proprietors without a business tax ID, with some limits, such as one approved number.

What to watch out for

Services that skip registration. Texts from unregistered numbers can get filtered without warning.
Texting people who didn't contact you. Carriers and the law are strict about unwanted marketing texts. Replying to someone who just called you is very different from blasting a list.
Ignoring STOP. Every business text program should honor opt-outs.

How JobCatcher handles it

When you go live, we get your local JobCatcher number and register it with the carriers for you. Going live has a one-time $35 activation fee, which covers that registration. Carrier approval usually takes a few business days, and your first month is charged with the activation fee when you go live. Texts only go to people who just called you, and anyone who replies STOP never hears from us again.

What happens if you text without registering

US carriers filter or block texts from business numbers that aren't registered. Messages may arrive late, get marked as spam, or never arrive at all, and you often won't be told. For a missed call text back, that means the customer you were trying to catch never hears from you.

What you'll be asked for

Registration asks who is sending the texts (your business name and details), what kind of messages you'll send, and how people agree to get them. For a sole proprietor, there's usually a simpler path that verifies you with a mobile number.

Tips for a smooth approval

Use your real business name, consistently. Only text people who contacted you first. Always include a way to opt out, like Reply STOP. Messages that look like marketing blasts are more likely to be filtered.

Common questions

How long does 10DLC registration take?

It varies. A few business days is common, but it can take longer if carriers ask for changes.

Do I need 10DLC to send texts from my business?

If you send texts from a regular 10-digit local number through software, yes. Unregistered business texting is filtered or blocked by US carriers.

Does JobCatcher handle 10DLC?

Yes. Getting your local number and registering it with the carriers is what the one-time $35 activation fee covers. Approval usually takes 3 to 5 business days.

Stop losing jobs to missed calls. JobCatcher texts every missed caller back in seconds and lets them book a time inside your hours. From $39/month, no contract.
