How to Register New EON Card Number in Online Banking?

Are you getting an “Unauthorized Usage” error when you log in to EON CyberAccount Online Banking?

This error is something not to fret about. It occurs if the log-in account associated with your EON card was revoked by UnionBank. Perhaps, you applied for a replacement because you lost your current card, or maybe, it was already expired. If so, UnionBank will temporarily deny your access to online banking. During this period, you will not be able to use your account in any transactions, for example, online shopping or fund transfer.

Update EON Card Number in Online Banking


To be able to regain access to your online banking account, you must send a request to UnionBank to update your account information. Before doing the steps below, you must ready the following:

  • Old Username or User ID – This will be your permanent username.
  • Old EON card number (16-digit)
  • New card number
  • New four-digit ATM card Personal Identification Number (PIN)

If you haven’t saved a copy of your old card number, you can still get a copy by calling UnionBank customer service at 02-841-8600 or 1-800-1888-2277 (Domestic Toll-Free Number available to PLDT subscribers). This is the faster way to get the old card number instead of emailing them.
