The incumbents on the businesses, McCann Erickson, Universal McCann and MRM, have not been asked to repitch.
The review, which is being handled by the AAR in London, will, however, include the Martin Agency, the company's US incumbent, and a group offering from Interpublic.
McCann's most recent UK campaign for UPS, which broke in 2006, featured Jean Reno as a time-travelling character. The ad promoted the company's Quantum View technology, which allows customers to track the location of their parcel.
Last week, UPS reported quarterly net income of $401 million, down 56 per cent. Revenues fell 13.7 per cent to $10.9 billion. The company said that it expected revenues in all markets, except China and Poland, to fall over the next quarter.
