What is my library card number (or patron ID)?

FAQ: What is my library card number (or patron ID)?

Answer:

Your library card number (also called your patron ID or account number) is the 14-digit number found on your library card, near the barcode. 

Cards issued by Marathon County Public Library (MCPL) or any other public library in the Wisconsin Valley Library Service (WVLS / V-Cat) are valid for access to MCPL catalogs and resources. (Note: Some MCPL resources are only accessible to MCPL patrons.)

If no longer have your library card (but have had one in the past), please contact us to request a new card.

If you've never had a library card with MCPL or any other public library in WVLS / V-Cat, please apply for a library card online
