Yes of-course you can know and check whether anyone of your contact, friend or foe is blocking you intentionally. There are two ways to check whether you are blocked or not.
Here are tips to check whether you are blocked by person:
Updated: checking with WhatsApp Web:
Few months back WhatsApp added Whatsapp Web for accessing chat conversation from web browser like chrome for better usability. So we are going to use same WhatsApp for web to check the status of block.
- Login using WhatsApp for Web.
- Click on New Chat icon.
- Search for the person to whom you wanted to check.
- Check Status on WhatsApp.
- If WhatsApp status on WhatsApp Web is appearing as “Hey there, I am using WhatsApp.” but from mobile phone if it is appearing as BLANK then you are 101% blocked by person.
- If WhatsApp status on Web as well as on mobile phone is appearing as BLANK then your contact is not added and they have made privacy setting restricted to contact only.
I have personally checked with me and my friend’s device for confirmation, the above method works like charm.

There are few alternative method to check whether you have been blocked by a person.
NO status under contact name:

There will be NO status such as Online or Last seen at… in chat window. It will be completely blank. If it is so than you might been blocked by person.
Note: Make sure you have working connection ON, sometimes without packet data it won’t show statuses.

Message not delivered:
Blocking a contact means, he/she won’t be able to send you messages. If you are blocked you then you wont be able to send him/her any messages.
So check whether your message are getting delivered or not. This can be checked by looking at tick mark beside your message.
For 1 Tick mark: Your message is sent but not delivered to contact.
For 2 Tick mark: Your message is sent and delivered to contact.
For 2 Tick mark in Blue Color: Your message is read by receiver.
In blocked case, you will be getting only one tick mark means your messages have been sent but didn’t delivered to person.
Update: Due to Privacy Setting (Last Seen, Hide statue and Profile Pic), it had became very difficult to track but latest added using WhatsApp Web works awesome.
