The final closing of your resume can read, "References on Request," or "References Available upon Request."

 

Some candidates don't use this as a close, however, and the prospective employer generally will assume you have references to offer. An employer will not hesitate to ask for references when needed and they most always are.

 

Consider writing a separate page listing a few really good references. Include contact information, as well. You can hand this page to your prospective employer when needed and so, this is always good to have on hand.
