# Inbound keyword opt-in
<a name="registration-help-optin-keyword"></a>

Use this pattern for **promotional advertisements** (flyers, webpages, emails, social posts, in-store signage) that advertise a keyword for users to text. All required disclosures must appear on the advertisement itself. The user texts the keyword to opt in, and the auto-reply confirmation must also contain all disclosures.

## What makes this compliant
<a name="registration-help-optin-keyword-compliant"></a>
+ **All disclosures on the advertisement** — Brand name, message purpose, frequency, data rates, STOP/HELP instructions, Terms of Service link, and Privacy Policy link are all visible on the ad.
+ **Clear keyword and number** — The CTA clearly states the keyword and number (e.g., "Text JOIN to 12345").
+ **No checkbox needed** — Texting the keyword is the consent action (user-initiated).
+ **Auto-reply must also contain disclosures** — The confirmation message sent after the user texts the keyword must repeat all required disclosures (brand, frequency, data rates, STOP/HELP).
+ **Registration describes ad placement** — The registration submission must describe where the keyword is advertised and provide a screenshot or photo.
