How do I get a library barcode number and PIN?: Home

This LibGuide explains how to obtain a library barcode number and PIN. These are essential for viewing your individual library account, placing holds on materials in the catalog, and renewing eligible items online.

If you'd like to request and renew library materials using the Mayo Clinic Libraries online catalog , you'll need two things: your Library Barcode, and your Library PIN. The sections below contain instructions for setting up both your barcode and PIN. Set up your barcode first, as you'll need the barcode to create your PIN.

Once you have established your PIN, you can log into your library account and:

  • Request items
  • Renew eligible items

To return to your library account in the future, simply use the "My Account" in the main menu bar on any library page.  You'll need your name, Library barcode (the barcode number on the back of your Mayo badge), and the PIN you just created.

Tips on creating or changing your PIN

1. Key in a 4-digit PIN (no letters) of your choice. 
The PIN must not contain:

  • A common trivial pattern (for example, 1234 or 4321).
  • A character that is consecutively repeated three or more times (for example, 1111).
  • A set of four numbers that is consecutively repeated two or more times (for example, 1212).

2. After entering a valid PIN, you will be asked to enter it again for verification. 

3. If you've forgotten your PIN, you can reset it. Click on the "Forget Your PIN?" button.

  •       You'll need to enter your last name and barcode number.
  •       You'll receive an email with a link to reset your PIN. If you don't receive a PIN reset email within 24 hours, please contact your local campus library.
