# Understanding SMS Consent
> Learn how your business can grow your SMS List in a compliant manner.
SMS marketing is a highly regulated medium, so we’ve prepared this article to make sure that you understand all the requirements needed to collect textable phone numbers from your clients in a compliant manner, and answer any questions you might have around consent.
**Before we get into the details, make sure that you:**
Are subscribed to Privy's Growth Plan, which includes access to all our SMS features.
Have already registered for your toll-free number and been approved.
Will only be collecting and sending messages to numbers in the United States and Canada (+1 country code)
## How do I collect SMS contacts?
At this time, the only way to collect SMS Contacts at Privy is to have them sign up via a Privy display. The display must include a phone number field and our SMS Opt-In legal disclaimer. Privy Convert Displays are included in your Growth Plan subscription.
To add a phone number field and SMS Opt-In legal disclaimer, you can either:
1. [Create a new display and select a template that Collects SMS Subscibers](https://help.privy.com/docs/learn/displays/create-a-display#choose-a-template)
2. [Add a new phone number form field](https://help.privy.com/docs/learn/displays/form-fields-and-elements#form-fields)
3. [Add a new phone number collection step](https://help.privy.com/docs/learn/displays/create-a-display#add-and-delete-steps)
Once a contact signs up, their path to becoming textable depends on the display's [SMS Opt-In setting](/docs/learn/contact-management/sms-opt-in). By default, contacts must complete the Double Opt-In process by replying 'Y' to a confirmation text. You can also switch a display to Single Opt-In to make contacts textable immediately on submission.
### Privacy Policy and Terms & Conditions
You must update the links in your display's SMS Opt-In disclaimer to match your brand's Privacy Policy and Terms of Service.
To do this, click directly on the SMS Opt-In disclaimer element in your display, and then paste your brand's Privacy link and Terms link in the fields on the right:
At this time, these links must be updated individually for any of your displays that are collecting SMS Consent.
## How does SMS Double Opt-In work?
To become a textable contact on your list, your contact must complete both parts of the Double Opt-In process:
Signed up on a Privy display with their phone number and the SMS Opt-In legal disclaimer present.
Replied 'Y' to the Double Opt-In message they receive immediately after signing up.
Here's what the Double Opt-In message from your business will look like:
Once the contact replies 'Y', they will officially be a textable contact on your list + receive all your messages moving forward!
If a contact does not reply 'Y', they will not be textable.
## How do contacts Unsubscribe and/or Resubscribe?
To unsubscribe, contacts need to reply STOP to any of your toll-free number's messages. This guidance is included at the end of each of your texts.
To resubscribe, a contact can either reply UNSTOP or START to your toll-free number's messages.
They can also sign up on one of your displays again. They may or may not need to complete the Double Opt-In process again.
## FAQ
**Can I send text messages to anyone that gives me their phone number?**
*No. You can only send text messages to contacts who have given you explicit consent to receive marketing text messages. For sign-ups on a Privy display, consent is captured through one of Privy's [SMS opt-in flows](/docs/learn/contact-management/sms-opt-in); for contacts brought into Privy another way (for example, imported with pre-existing consent), you're responsible for ensuring the consent was collected in a TCPA-compliant manner.*
**Can I send text messages to contacts that opted-in to receive emails from me?**
*No, email consent is separate from SMS consent and must be collected through its own opt-in flow on a display. Privy supports both [Single Opt-In and Double Opt-In](/docs/learn/contact-management/sms-opt-in) for SMS sign ups.*
**Am I required to have an opt-in checkbox on my displays to collect SMS consent?**
*No, a checkbox is no longer required for SMS consent. You still have the option to add one if you'd like.*
**Can I import textable phone numbers to my Privy account?**
*If you have existing textable contacts, you can import them via spreadsheet. They need to have been collected* *in a TCPA-compliant manner. Please note that by submitting a list for upload, you certify that you collected subscribers in a TCPA-compliant manner. If you're not sure, please consult your attorney.*
