Last Call Return, commonly called Call Return, is a telephone feature code offered by telephone service providers to give a called party the time and telephone number of the last received call, and may also offer the facility to place a call back to the calling party.

The access number for this facility varies per country and provider:

In the UK, after dialing "1471", the caller can press "3" to automatically return the call. Until August 2004, this service was free; since that date it has incurred a charge, as of 10 January 2007 a per call fee of 10.5 pence is charged. It was the topic of a 2001 episode of the sitcom Coupling.

The service provider may also offer a facility through which the calling party can prevent their number being revealed to the called party, either permanently or on a per-call basis. This is achieved by prefixing the dialed number with:

  • United Kingdom: 141 on landlines, and #31# on mobile phones
  • United States: *67
  • Australia: 1831

Conversely, to send the caller number on a line where the number is normally withheld, the following prefixes can be dialled:

  • Ireland: 142
  • United Kingdom: 1470 (also used in Gibraltar)
  • United States: *82

In Ireland and Gibraltar, ex-directory or unlisted numbers are withheld by default.

In Canada, the feature is commonly marketed by telephone companies as a combination of two features:

  • Call Again, a form of automatic ring back, allows a caller, on reaching a busy signal, to hang up, dial a special code, and be called back automatically when the called number is no longer busy, usually with a limit of 30 minutes.
  • Call Return allows a customer to dial a code that identifies the last incoming call. On some types of central office equipment, it announces the number and offers the call-back option; on others, it simply attempts a connection without an announcement.
