Every WhatsApp message carries a tiny status display: a clock, one grey tick, two grey ticks, or two blue ones. Those four states, plus the Message info screen behind them, are WhatsApp’s entire delivery-report system, and they get misread constantly.
This guide decodes each state, explains read receipts and exactly what turning them off does (and does not do), walks through the per-message delivery report, and covers the other meaning of "report": flagging a chat to WhatsApp.
What the ticks mean
The transitions carry information too. A message that jumps straight to two ticks reached a phone that was online. A message parked on one tick is waiting for a phone that is off, out of coverage, or, in one specific case, belongs to someone who blocked you.
- Clock icon: the message has not left your device yet. You are offline or the send is pending.
- One grey tick: delivered to WhatsApp’s servers, but not yet to the recipient’s phone.
- Two grey ticks: delivered to the recipient’s device. Not read, just received.
- Two blue ticks: the recipient opened the chat and the message was read (or seen, for media).
Stuck on one tick: offline or blocked?
One grey tick that persists means the recipient’s phone has not received the message. In order of likelihood: their phone is off or has no data, they reinstalled or changed numbers, or they blocked you. A block keeps your messages on one tick forever, but so does a phone in a drawer, so duration alone proves nothing.
The distinguishing evidence lives elsewhere: last seen gone, profile photo frozen, calls that never connect. One tick is only one line of that picture.
Read receipts: turning blue ticks off, and the price
Settings, Privacy, Read receipts toggles the blue ticks. Turning them off is mutual disarmament: others stop seeing when you read, and you stop seeing when they read. WhatsApp does not sell one-way invisibility.
Two exceptions survive the toggle, by design:
- Group chats: read receipts always function in groups, regardless of anyone’s setting.
- Voice notes: the played receipt (the mic icon turning blue) shows even with read receipts off.
People also read without triggering blue ticks at all: a message can be fully read from the notification shade or lock screen preview and stay on two grey ticks until the chat is actually opened. Two grey ticks never proves unread.
Message info: the per-message delivery report
For any message you sent, long-press it and choose Info (or swipe left on iPhone). The Message info screen is WhatsApp’s delivery report: a Delivered timestamp, a Read (or Played) timestamp, and in groups, the same broken down per member: who received it, who read it, and when.
This is also how broadcast senders check reach: each recipient’s copy is an individual message with its own delivery state, so the info screen, not the broadcast list, tells you who actually got it.
The other "report": flagging a chat to WhatsApp
Separate from delivery reports, WhatsApp lets you report an account: open the chat, tap the name, and choose Report (or Report and Block). Reporting forwards the most recent messages from that chat to WhatsApp for abuse review, along with the reported number. The reported person is not notified.
Use it for scams, phishing and spam rather than merely annoying contacts; accounts that accumulate reports face restrictions and bans. For anything personal, blocking alone does the job without involving WhatsApp.

Reading tick data as a business
For a business number, ticks are a crude but honest funnel: sent, delivered, read. A pile of one-tick messages usually means dead numbers or blocks; delivered-but-never-read at scale means your messages stopped being worth opening. Both are signals to fix targeting and frequency before WhatsApp’s systems fix them for you.
Teams that outgrow reading ticks one chat at a time typically move to a shared inbox layer where conversation state (who answered, what is still open) lives above the tick level; the ticks stay what they are, a per-message receipt.
