How to Change a BlackBerry Registration ID

The BlackBerry registration ID number is a number used by cellular carriers to program BlackBerry phones with carrier settings. The most common reason for changing the registration ID is if you switch carriers, if you are moving out of the country or if you are going on vacation and wanting to temporarily use a service provider not available in your own country. Keep in mind that more than just the registration ID number would have to be configured to change service providers. Be mindful of the changes made to your Blackberrys programming, because you could end up permanently disabling your phone.

    Press "##" followed by the one-time use, six-digit code located in the "Programming Instructions," followed by an additional "#." (For example, ##123456#. The last # entered will not appear on the display.) If this is not a new phone, instead of using the one-time, six-digit code, use the secondary six-digit code, located in the instructions. The "Programming Instructions," can be found in your BlackBerry's user guide. If you no longer have the user guide, it can be downloaded from the BlackBerry website (see Resources).

    Scroll down to the "BlackBerry Registration ID" field.

    Use the "Delete" key to delete any numbers that may already be in the "BlackBerry Registration ID" field. If you have a used device, there may be a registration ID entered by the previous owner.

  4. 4

    Enter the new registration id number in the "BlackBerry Registration ID" field. Press the "Menu" button, and then "Save." A "Re-writing the device" message will pop up when the process is complete, and the device will reboot itself.
