Switching SMS providers without losing your numbers or your opt-outs
Changing texting platforms is manageable if you plan it: porting numbers, handling 10DLC registration, and — most importantly — carrying your opt-out list and consent records with you.
·3 min read
Businesses switch texting providers for all kinds of reasons: better pricing, better features, better support, or deliverability problems that never got fixed. The switch itself is very doable, but it has a few steps that cause real problems when they are skipped.
This guide walks through a switch in order: what to export before you do anything, how number porting works, what happens to your carrier registration, and how to cut over without a gap in service.
Before anything else: export your opt-outs and consent
The most important step happens first, while you still have full access to your old account. Export your complete opt-out list and your consent records, and keep copies.
Your obligation to honor opt-outs does not end when you change platforms. If someone opted out through your old provider and you text them from the new one because the list did not come across, you are contacting someone who told you to stop. Import the opt-out list into the new platform before you send a single message from it.
- ✓Your full opt-out / suppression list
- ✓Consent records — when and how each contact opted in
- ✓Your contact list and any tags or segments
- ✓Conversation history you need to keep
- ✓Templates and campaign content worth reusing
Porting your numbers
If customers know your numbers, you will want to keep them. Porting moves a number from one provider to another. You typically submit a request through the new provider with a letter of authorization and details that must match the old account exactly — account name, number, and sometimes an account PIN.
Mismatched details are the most common reason ports get rejected, so get the exact account information from your old provider first. Porting can take anywhere from days to a few weeks, so plan for it.
What happens to your 10DLC registration
Business texting from standard local numbers generally requires a registered brand and campaign with the carriers' registry. When you switch providers, that registration does not automatically follow you in every case.
Depending on the providers involved, your existing registration may be able to move, or you may need to register your brand and campaign again. Ask both your old and new providers how they handle it before you port anything, because a number that arrives at the new provider without an approved campaign may not be able to send messages right away.
Toll-free numbers
Toll-free texting has its own verification process. If you text from toll-free numbers, ask the new provider whether your existing verification carries over or whether you will need to submit it again, and factor any review time into your plan.
Cutting over without a gap
Keep your old account active until the port is fully complete and you have confirmed that texts send and receive correctly on the new platform. Cancelling too early can interrupt service or, in the worst case, put a number at risk during the port.
Schedule the switch for a quieter period rather than the middle of a big campaign. Once the port completes, send test messages in both directions, confirm replies land where your team expects, and check that opt-outs are processed correctly on the new platform before resuming normal volume.
A simple switching checklist
Most switching problems come from doing these steps out of order. Work through them in sequence.
- ✓Export opt-outs, consent records, contacts, and history
- ✓Import the opt-out list into the new platform first
- ✓Confirm how 10DLC and toll-free registration will be handled
- ✓Get exact account details from the old provider and submit the port
- ✓Keep the old account active until the port completes
- ✓Test sending, receiving, and opt-outs before resuming volume

Frequently asked questions
Can I keep my texting number when I switch providers?
Usually, yes, by porting it. You submit a request through the new provider with a letter of authorization and account details that match the old account exactly. Porting can take from days to a few weeks.
Do I need to redo 10DLC registration when switching providers?
It depends on the providers. Some registrations can move between providers; in other cases you may need to register again. Ask both providers before porting so your numbers can send messages as soon as they arrive.
What happens to my opt-out list when I switch SMS providers?
It does not move automatically. Export it from your old provider and import it into the new one before sending any messages, because your obligation to honor opt-outs continues regardless of platform.
