How WhatsApp Check Marks Work
Check marks on WhatsApp appear to the right of each of your messages. When you send your message, it is marked with a single gray check mark. When the message reaches your recipient’s device, you see a second gray check mark, and when the recipient reads your message, the check marks turn blue. Group messages use the same system, but they’re a little different. When sending a group message, you get the double check marks only when the message has been delivered to all members of the group. Similarly, the double check mark only turns blue after all members of the group have seen the message.
Beyond the Check Marks on WhatsApp
If you’re wondering why your recipient hasn’t read your latest message, you can dig a little deeper and get more information. At the top of your message thread, you’ll see your recipient’s name and the last time they were online. It’s possible they just haven’t been online since you sent it, or they’ve blocked you.
How to See When a Message Was Received
You can also find out specific times and dates when a message was received and read. Long-press on a message to select it. It will highlight in blue. At the top of your phone screen, tap the i icon. On the message info screen, you’ll see the time and date when the message was delivered and read.
How to Turn Off WhatsApp Read Receipts
All of this works because WhatsApp delivers read receipts. When a message is read, a little bit of data is sent back to the message sender. Read receipts are turned on by default, but they can be turned off.
