Think of the tiers like levels in a video game: you start with limited powers, and as you earn trust with WhatsApp, you unlock greater messaging capacity. Each tier determines how many unique users you can contact per day with business-initiated messages.

WhatsApp Business API Tiers & Daily Limits

Tier	Outbound Message Limit (24h)	How to Reach It
Tier 0 – Rookie	250 unique users/day	Default for new, unverified numbers.
Tier 1 – Verified	2,000 unique users/day	Verify your business on Meta to obtain an approved display name.
Tier 2 – Advanced	10,000 unique users/day	Automatically granted after using ~50% of Tier 1 in 7 days (≈1,000 conversations) with medium/high quality.
Tier 3 – Expert	100,000 unique users/day	Automatically granted after using ~50% of Tier 2 in 7 days (≈5,000 conversations) with medium/high quality.
Tier 4 – Legendary	Unlimited	Automatically granted after using ~50% of Tier 3 in 7 days (≈50,000 conversations) with medium/high quality. Only for highly trusted companies.

Note: “Conversations” refers to initiated chats outside the 24-hour customer support window. Replies within the 24-hour window do not count toward the limit.

How Do You Level Up?

1. Verify Your Business (Tier 0 → Tier 1)
Complete Business Verification in Facebook Business Manager and get an approved WhatsApp display name.

2. Maintain a High-Quality Rating
Keep your message quality Green (High) or Yellow (Medium). Too many blocks or spam reports will lower your rating and prevent tier upgrades.

3. Use at least 50% of your Tier Capacity Weekly
Meta evaluates your usage over 7 days. For example:

Tier 1 → initiate ~1,000 conversations (50% of 2,000)

Tier 2 → initiate ~5,000 conversations

Tier 3 → initiate ~50,000 conversations

When these conditions are met, your tier is automatically upgraded.

Practical Examples

Small Startup in Tier 1

800 contacts → send messages gradually to maintain quality → after a week, Tier 2 automatically unlocked.

E-commerce Campaign (Tier 2 → 3)

8,000 contacts → split sends across days, maintain engagement → Tier 3 unlocked in 7 days.

Enterprise to Tier 4

Large-scale usage with high-quality messaging → tier upgrades gradually to unlimited capacity.

Always send opt-in messages only.

Keep high-quality templates to avoid rejections.

Do not exceed your current tier; gradually increase volume.

Replies within 24 hours do not count toward your outbound limit.

Portfolio-level limits apply: all numbers under the same business share a combined limit.

Start small, focus on message quality, and your WhatsApp Business API tier will grow automatically. Higher tiers allow larger campaigns, but maintaining trust is key; think of it like leveling up in a game: progress step by step to unlock the full potential of WhatsApp Business API.
