What is BlackBerry PIN-to-PIN Messaging?

BlackBerry devices all have a unique ID, otherwise known as a PIN (Personal Identification Number). A PIN can be used to send secure messages to other BlackBerry users, also called "peer to peer" messaging.

BlackBerry "scrambles" PIN messages but does not actually encrypt them, so be careful when sharing your PIN with others.

What BlackBerry Devices Support PIN Messaging?

BlackBerry 7 OS and earlier, as well as BlackBerry 10 version devices, support PIN messaging. Subsequent to BlackBerry 10, the BlackBerry OS was discontinued and the later BlackBerry devices use the Android operating system.

How Does PIN Messaging Work?

The PIN is a string of 8 alphanumeric characters that is hard coded into your BlackBerry, and cannot be changed. The BlackBerry Internet Service (BIS) recognizes your BlackBerry by its PIN, so it knows where to deliver your email messages. BlackBerry Messenger (BBM) uses the PIN protocol to deliver messages to other BlackBerry users.

PIN Messaging is simply sending a message using the BlackBerry PIN protocol from one BlackBerry directly to another BlackBerry. PIN messages are more secure than email messages, because they are scrambled and travel from one BlackBerry to another only via the cellular networks. They do not traverse the internet. PIN messages appear in the BlackBerry Messaging application along with email messages.

If you have friends on BBM that you would like to send direct PIN messages to, you can retrieve their PIN from their BBM contact. If you have your BBM contact in your BlackBerry's Contacts, you can link it to their BBM contact so that you can send them PIN messages straight from the BlackBerry Contact list.

How Secure is PIN Messaging?

If you choose to give out your BlackBerry’s PIN, remember that it cannot be changed, so keep your BlackBerry's security in mind and give your PIN only to people you trust.

Further, BlackBerry specifically states that a PIN message should be considered "scrambled, but not encrypted." This means that any BlackBerry device can access and read any message it receives, even if that device is not the intended recipient. 

BlackBerry offers an enterprise encryption service, BBM Protected, that can encrypt BBM messages between devices.

Non-PIN BBM Messaging with Users on non-BlackBerry Devices

If you have a BlackBerry and want to communicate with contacts who have non-BlackBerry devices, such as Android, iOS or Windows devices, you cannot use PIN messaging— but you can still take advantage of BBM messaging to pass messages back and forth.

First, your contact needs to install the BBM Messenger app for his platform. You can then search the app on your BlackBerry to find them and add them to your BBM contacts.
