# A2P Registration Requirements

## Do I Need A2P for WhatSnap SMS?

**No**, you do **not** need A2P (Application-to-Person) registration when using WhatSnap with your own SIM card.

{% hint style="success" %}

* ⚠️ **Carrier fair use policies** apply
* ⚠️ **Device required**: Need Android phone + SIM card running 24/7

**Best For:**

## What Registration IS Required for WhatSnap P2P?

While A2P registration is not required, you still need **standard mobile carrier registration** (same as any normal phone plan):

### Required for SIM Card Purchase

**Typical Requirements:**

* ✅ **Government-issued ID** (driver's license, passport)

**Varies by Country and Carrier:**

* Some carriers have stricter requirements
* Business plans may require business documentation

### Recommended: Register in Client's Name

If setting up WhatSnap SMS for a client:

**Best Practice:**

1. **Get client's credentials** (ID, address)

4. **Client owns the number** (you just manage it)

**Benefits:**

* ✅ Easier compliance documentation
* ✅ Reduced liability for agency/consultant

{% hint style="info" %}
