Existing Citi Virtual Account Numbers Will No Longer Work
Citi has a message on its website, informing cardmembers of upcoming changes to Virtual Account Numbers. But it looks like Citi won’t be able to make changes to this feature while also keeping old Virtual Account Numbers active.
Starting August 24, you will need to create new Virtual Account Numbers, as the old ones will no longer work.
Here’s the text of the message:
Weโre updating your Virtual Account Number experience. Starting August 24th, numbers created on or before August 23rd can no longer be used to make a purchase. Create new Virtual Account Numbers on or after August 24th to avoid any inconvenience.
