# What is the character limit for the WhatsApp template name?

# Quick answer

The template name in MyOperator must follow Meta’s strict format rules to be accepted. These rules ensure smooth API processing and compliance with WhatsApp Business Platform guidelines.

---

## Character Limit

* Minimum: 1 character
* Maximum (technical): 512 characters
* Best practice: Keep names under 50 characters for readability and easier management.

---

## Invalid Characters

Template names cannot include:

* Spaces → `order confirmation` 🚫
* Special characters → `order#update`, `order@2024` 🚫
* Uppercase letters → `OrderUpdate` 🚫

---

## Valid Format

* Use only lowercase letters, numbers, and underscores.
* Must be unique across your WhatsApp Business Account.

---

## Examples

| Template Name | Valid? | Reason |
| ---- |
| `order_update_123` | ✅ Yes | Uses lowercase letters, numbers, and underscores only |
| `OrderUpdate2024` | ❌ No | Contains uppercase letters |
| `order update` | ❌ No | Contains a space |
| `order#update` | ❌ No | Contains a special character `#` |

## What Happens If You Violate the Rules?

* You will not be able to proceed with creating the template.
* MyOperator will show an error message.
* You’ll need to rename and resubmit following the correct format.

## Best Practices for Naming Templates

* Keep names short and descriptive (under 50 characters).
* Use prefixes by use case for easier management:

* `order_update_2024`
* `promo_summer_sale`
* `otp_login_flow`

* Avoid generic names like `template1` — they make it harder to track usage later.

| Tip Treat template names as internal identifiers — customers won’t see them, but clear, consistent naming will save time for your team during approvals, audits, and reporting.
