It comes as part of an extension of the bank's services for personal and business users and also applies to customers at RBS and NatWest.
Stephen Cruise of Ulster Bank, said: "We're continually looking for ways to enhance the service that our customers need and to make banking more convenient for them.
"Building on our existing partnership with the Post Office, these extended services are another way in which we are providing greater choice and flexibility for our customers."
There are 482 Post Office branches across Northern Ireland, where Ulster Bank customers can already check their balance, withdraw cash and pay bills.
Mark Gibson from the Post Office NI said he believes the addition of the extra services will bring a "real benefit" and "will offer people even more options."
